Description

Digital content combined with virtual objects and real-world images

The invention relates to an interactive digital content, in particular to the real-life image as a background, the dynamic output of the sports equipment or the motion sensing of the active person, and the virtual person or object corresponding to the sports equipment or the activator is placed in the real scene image for interaction. Change.

The traditional virtual reality is modeled and designed by computer simulation software, which can be used to model the actual landscape in three dimensions and to create a variety of virtual people. Animals or objects are integrated into it to interact, but the time, manpower and cost are not only more, but also the fidelity is not as good as the actual scene. Therefore, there is a technology that replaces the landscape modeling with the actual shooting photos, but such landscape photos can not produce a sense of continuity, such as the street scene provided by GOOGLE MAP, and can not be virtual people in the browser or Objects are placed into real-world images for interactive changes. Therefore, the actual scenery of the scenery or the building or the indoor film is used as the real scene, and it has the characteristics that the virtual reality can interact with the viewer or the user, or further the virtual person or object corresponding to the sports equipment or the activator is placed. Real-world imagery changes interactively, virtual people or objects can be multi-person participation and based on the dynamic output of physical sports equipment distributed throughout or the motion-sensing output integration of the activist, interaction and competition are all worth developing. Technology and products.

In addition, online games are a kind of video game where players can connect through the Internet, control their own created virtual characters, interact with other players and develop relationships, share common interests, and achieve entertainment effects by manipulating virtual characters. The current online games mainly use drawing software to draw backgrounds and virtual characters. It is also a problem of high production cost but low fidelity, and few online games that directly interact with sports equipment directly appear on the market.

One of the objects of the present invention is to make a real scene using a film that actually captures a landscape, and to have a feature similar to that of a virtual reality that can interact with a viewer or a user.

Another object of the present invention is to provide an interactive digital content, in particular to use a real-life image as a background, with the dynamic output of the sports equipment or the motion sensing of the active person, and the virtual person corresponding to the sports equipment or the active person or Objects are placed into real-life images for interactive changes.

Another object of the present invention is to provide an interactive digital content, in particular, an online sports game with a live view as a background, a dynamic output of a fitness equipment, or an action of an active person, and the player can connect through the Internet. By using fitness equipment to control the virtual objects created by themselves, interacting with other players and developing relationships, sharing common interests, and achieving entertainment effects by manipulating virtual objects.

"Creation of virtual objects"

The virtual object includes a person, an animal, an article such as a vehicle, a bicycle, a boat, etc., and the manufacturing method generally includes the following: drawing a virtual object action diagram such as running, decomposing into a plurality of, for example, 14 continuous motion images, and converting into GIF plays the file, the more the decomposition action, the more delicate the action, but the storage and operation are more resource-intensive.

Actually, a virtual object action map such as running is taken, and is divided into a plurality of, for example, 14 consecutive action photos, and converted into a GIF dial. When shooting, you can do it in front of the blue curtain for easy back. In addition, it is necessary to simulate various face-oriented actions of the virtual object, which can be photographed from different angles, for example, at least four face-to-face virtual object action GIFs of the front side, the back side, the left side, and the right side.

In order to achieve a realistic sense of dynamics, the GIF objects produced can be subdivided into basic objects. With special effects items. Basic objects can show several effects:

1. The speed of the virtual object can be synchronized by changing the speed of each picture or photo in the GIF file according to the action of the real object. For example, the elliptical machine has a stride distance of s. If a pulse signal is generated every time a step is completed, and the period is t, the speed of the film is s/t, and the GIF picture is to be retracted by a loop. By counting the period generated by the pulse signal, the speed of each picture or photo in the GIF file can be adjusted.

2. The enlargement and reduction of the virtual object can be achieved by changing the picture size of the GIF file, which is used to show the perspective of different virtual objects, especially when used for multiple people to participate in the competition.

3. The rotation of the virtual object can be achieved by rotating the picture of the GIF file to show the tilting posture of the virtual object when tilted with the ground or the water surface, especially for the left and right tilt of the bicycle through the curve, or the two virtual objects are mutually When colliding.

Special effects objects are other orientations or poses that provide additional pictures or photos to show virtual objects, such as turning heads, leaning forwards, leaning back, sideways, etc., such as when riding a bicycle, or turning around at multiple intersections. Time. In addition, in order to achieve a shadow effect, you can add a shadow when drawing or post-production.

Since the position of the user is fixed when the fitness equipment is used, the present invention can select at least one camera to be placed on the electronic instrument of the fitness equipment or the position of the user's head on the television screen, especially the position of the eyes or the mouth or the nose, and also shoot The posture of the user's hand or foot. You can shoot the background without the user before using it, then the user will start shooting when using the fitness equipment, and use the back The way of the scene separates the user's image and directly creates a GIF file, so that the user can choose whether to update his virtual agent character every time the user uses the invention. If the network bandwidth is sufficient, you also choose to instantly transfer the currently shot movie to replace the virtual agent.

『realistic image production』

As shown in Figure 1, the car 1 is loaded with a dual-purpose three-wheeled bicycle and a trolley 6, and at least one high-speed camera 2 is installed on the top of the car for long-distance and high-speed shooting along the way. When reaching a scenic spot or a landmark point, the tricycle 6 is installed at least. A camera shoots a path or laneway, and the cart 6 is equipped with at least one camera to shoot a pedestrian walk or an indoor exhibition hall. In this way, the three can be combined to form a complete landscape film. It should be noted here that the three-wheeled bicycle or cart 6 used requires a platform with a good suspension system to set up the shooting equipment in order to make the captured images smooth and clear. When shooting, in order to ensure that the position of each shot is accurate, it is necessary to use the Global Positioning System (GPS) device 3 and add the odometer 8, acceleration 4 and gyroscope 5 for position and direction correction, the coordinate positioning accuracy is at least Within a few centimeters, match each frame of the film being shot with at least mileage and latitude and longitude and ground tilt. All of the above sensors can be recorded and stored by the notebook 7 on the car. In addition, the above-mentioned camera can also be replaced with a stereo camera to provide stereo image capture and post production.

As shown in Figure 2, filming on the road often has many opportunities to encounter the opposite direction of the same vehicle, locomotive, bicycle, pedestrian, etc. The worst thing to deal with is the vehicle in front of the same lane 15 (hereinafter referred to as He car 14), if it is a shooting vehicle (to I call it a car. I am at the same distance from his car. I don’t overtake or slow down, so that his car and my car are pulled apart, or keep the front of my car, then basically this kind of film will cause the real image user. Troubled. Because if he wants to overtake, it is basically not easy to achieve a virtual effect. The reason is that the video playback is based on the shooting position of my car, that is, the virtual vehicle driven by the user (hereinafter referred to as my car) is completely a substitute for the role of my car in the virtual reality. If there is no collision when actually shooting the real scene. The condition of his car will not collide in the virtual world.

Of course, if it is possible, when shooting in a real-life image, it is best to maintain the widening of the field of vision, that is, to maintain the clearance in front of my car, so as to facilitate the addition of the car when the film is post-production. The car is the method of making the virtual object. , making GIF files of various virtual vehicles and placing them in the same direction or opposite lanes in the virtual movie of the real world. The interaction between the proposed car and the car is easy to calculate and calculate. Part of it needs to be achieved after the actual filming of the post-production image processing technology.

The moving object of the opposite lane 13 in the real-life video film, hereinafter referred to as "opposite car" 11, basically obeys the obstacle of the car 12, and must be evaded or regarded as an extra point. There are two situations that can cause a collision: one is that there is a moving object 11 in the opposite lane 13 in the movie, and in order to avoid collision between the race cars, accidentally run to the opposite lane and hit the opposite moving object. 11; The second is the collision between the race cars. To achieve the effect of simulating a collision, you need to use image processing technology, or you need to encode the moving object on the film and mark its rectangular bounding box. When the user drives the virtual vehicle (the car) 12 and the front "opposite to the car" 11 interaction, if the rectangular bounding box of the car 12 is more than a certain proportion of the rectangular bounding box of the "opposite car" 11, for example 10-20%, that is, the collision is the same, if the overlapping area is higher, or If the speed of the overlapping two cars is higher than a certain ratio, it will be regarded as a serious impact, etc., and when hitting the "opposite to the car" 11, the deduction function should be generated, and the colliding car can be made to have its GIF map according to the degree of collision. The rotation is generated, and the car that simulates the collision rolls over.

If necessary, you can make a car to cover the car that will cause trouble in the film, or make a background map to cover his car into the background.

Because there are vehicles coming and going, it is necessary to take two-way shooting of the same road when shooting. If the user passively moves in accordance with the instructions of the riding vehicle on the playing route, the provided route is one-way. If the mode of operation allows the user of the present invention to voluntarily take turns at the intersection, all routes must be taken in both directions.

Crossroads or multi-junctions can be processed using the technique of ring photography. At least six cameras can be set up around 360 degrees. As long as you shoot at the center of the intersection or set up at least one camera to rotate 360 degrees at the intersection, you can borrow The film of the ring field is formed by the combination of the ring field and is used as a choice for intersections or multiple intersections.

Although the above description is exemplified by roads and vehicles, it is still applicable to the interaction of vessels between non-co-directional waterways or waters, and even between flying objects in the air. In addition, vehicles also refer to people, animals, bicycles, locomotives, etc. that can move on the road.

Using post-production technology to process real-life movies, like virtual reality drawing, requires a lot of manpower, because it is necessary to mark the surface of each frame or every few frames, as shown in Figure 3, usually the actual The photographed road surface 16 has three perspective curves, the road center divider line, the left line, and the right line. For the sake of simplicity of description, the curved road is temporarily not considered. The bottom and upper end points of the three line segments are: road center divider [(X _CB , Y _CB ), (X _CT , Y _CT )], left line [(X _LB , Y _LB ), (X _LT , Y _LT )], right line [(X _RB , Y _RB ), (X _RT , Y _RT )]. It is necessary to pay attention to the upper end point. In some cases, it may be collected into the same point, or the position may not appear on the upper edge of the frame. However, when the frame is made, it can be clicked and judged by the post-production personnel. For roads close to a straight line, the straight line equation can be used to represent the above three dividing lines. For curved corners, the curve equation is needed to approximate, as shown in Figure 4, in this situation, the post-production personnel need to select at least four points for each curve. The coordinates approximate the curve and require a total of twelve coordinates. Assuming these equations, it can be represented by X=f(Y).

In the frame coding, at least the six coordinates or twelve coordinates can be placed in the data item, and the main character virtual object or the first virtual agent 17 is placed in the center of the bottom line of the frame to the right. If there is a rear chaser or a second virtual agent 18, it will always be advanced from the right rear, and the virtual object or the third virtual agent 19 will immediately align with the center divider and gradually narrow down to The disappearance, the scale of the reduction can be estimated according to the GPS position of the lead and the GPS position of the main character.

The position of the virtual object can be directly used in the real scene by the post-production program. The range of the virtual object can be marked in the frame, similar to that shown in Figure 3 and Figure 4. As shown in Figure 5, it is composed of polygons 56, so that the user 57 can be used to communicate with the remote user 58, 59 Interaction, for example, a remote user can move left and right by an elliptical stepper or even a pressure pedal of the WII, because the underlying pressure sensor can detect the direction of the footprint change; or step in place, indicating forward.

In the calculation, the position of the surrogate can be estimated by the range of the virtual object motion formed by the equation X _R =f _R (Y) on the right line and the equation X _C =f _C (Y) of the central divider of the road, where Y= Y1+w△Y, Y1 represents the position of the first virtual agent in the current scene, △Y represents the transcendental transcendental amount, and w represents the weighting value of the camera's perspective effect, which can be experimentally calculated: fixed camera focal length The shooting position of the camera, the distance between the changer and the camera △Y, and the position (X, Y) and size of the image that the surpasser imaged on the screen, w=(Y-Y1)/△Y; X is in practice, Pick it so that it is between X _R and X _C. Because of the same road segment, there may be many people working together on the sports game. Everyone's position is known because it is accumulated through the exercise equipment movement; the position of each frame is also known because it is the mileage. The synchronization is synchronized, so the substantial excess ΔY is calculated from the distance between each participant. If the remote user's substantial excess ΔY is negative relative to the local user, indicating that it is behind, the proxy virtual object will of course not appear in the real virtual picture of the local user. When the substantial excess ΔY is positive, indicating that it is ahead, its proxy virtual object may of course appear in the real virtual picture of the local user, whether it appears, whether the end view Y=Y1+w△Y exceeds the movable range of the frame. .

"Virtual objects disappear in the corner"

How the virtual object disappears in the curve, because each shot has a corresponding triaxial acceleration, tilt, three-axis gyroscope, GPS measurement value, so it can be judged by the calculation result through the following description.

As shown in Figure 6, suppose Pa(t) is the position of the real character of the A-frame, Pb(t) is the position of the real character of the B-frame, Ca(t) is the shooting center of the A-frame, and Cb(t) is the B-frame. Shooting center. Ca(t) and Cb(t) are functions of mileage and GPS and can therefore appear on an aerial map. Let △ab(t)=Cb(t)-Ca(t), basically the direction of the front head can be approximated to the tangential direction of each point when shooting, assuming that the tangent to point A is Ta, and the tangent to point B is Tb. Therefore, according to the speculation of the shooting field, the virtual character size of Pb can be enlarged and reduced according to the distance of Δab(t), and the position of the A picture is calculated according to the aerial picture, and Pb(t) should be on the right side of the picture. When the angle between the tangent Ta and the tangent Tb is greater than a set value, Pb(t) will disappear in the A picture, and in the B picture, Pa will not appear because the Pa is behind.

The displacement and enlargement of a virtual person or thing, because many people compete or interact with each other in a real-life image, the relevant position must have a sense of perspective. For example, if the character's lead distance is a meter, then according to the perspective operation, The size of the virtual character should be adjusted according to the proportion of the actual characters in the film. If the character is caught up by the rear, its size should also be adjusted according to the proportion of the image entered. If it is a real character projection, the size of the avatar has a corresponding proportional relationship, especially When the two move side by side, the real characters will be larger and their virtual characters will become larger.

『Track transformation』

The exercise equipment with steering function, when appearing on the road for exercise, if the athlete moves the fitness equipment to move left and right, in addition to the visual field of the played movie to move left and right, the virtual object corresponding to the athlete needs to be in the movie. The road moves left and right. If other participants appear in the movie at this time, the interaction between the virtual objects corresponding to all the participants should pay attention to whether there will be a collision. Basically, all the athletes will follow the virtual objects in the picture. Move positions to each other and perform conversion of motion trajectories to avoid collisions. If the application is used, for example, when riding a bicycle to turn, or when turning around at a multi-section intersection, the virtual object corresponding to the athlete can use the special effect object to provide an additional picture or photo to show other orientations or postures of the virtual object, such as a rotor, Forward, backward, sideways, etc.

The virtual world of the present invention has multiple degrees of freedom. On the one hand, there is a real face of reality, on the one hand, there are virtual objects or stories or virtual tasks, which can be performed by people because the shooting of the reality is relative to the virtual reality. The production is easy and real, and because the characters can be directly converted into GIF files into the real scene, adding more realism and participation.

[Example 1]

The whole family can use it separately and record separately: user profile: basic information such as name, weight, height, three-dimensional size, health information such as heartbeat, blood pressure, breathing pattern and frequency, etc.

1. Personal accumulated mileage

2. Personal speed progress

3. Personal use record includes time, mileage, and tour route

4. User level: level, according to the accumulated speed and mileage, the user can upgrade or upgrade, for example, the actual speed can be multiplied by the upgrade weight to become the virtual speed.

5. Winning record: Participate in time-limited competitions and rewards, record points and accumulated bonuses, exchange points, exchange tickets for actual travel or get a bicycle or a new sports model.

Just as games on the market today can provide character selection, in this embodiment, a virtual bicycle or other kind of transportation can also be provided: a higher-grade vehicle can be replaced by upgrading or upgrading; and a virtual knight: picking a favorite star or himself . If you choose yourself, you will need to take your own GIF file upload.

As shown in Figure 7, for the two people in different places A and B use the network to walk, the sports equipment used is the elliptical machine 40, the screen shows a certain scenery on the North Beiyi Highway in Taiwan, red The virtual character 41 (GIF image file) represents the user of the A place, and the blue character avatar 42 (GIF image file) represents the user of the B place, and the two can perform the joint walking on the same road through the network. As can be seen from the figure, when two avatars appear somewhere on the road at the same time, they are indicated. The speed is quite the same. However, after the users of the B place, they quickly rushed forward. In the picture of the B, only the avatars in the blue are running, and the users in the A are behind, the virtual characters in the red disappear. In the picture. On the contrary, the avatar of the blue screen (the user of the B) gradually advanced, and the figure became smaller and disappeared at the end of the curve.

As shown in FIG. 8, the virtual character (GIF image file) of FIG. 5 is replaced with the GIF video file 43 and 44 actually captured by the user, resulting in a more realistic and integrated movie.

[Embodiment 2]

Since the 21st century, the global elderly population has been increasing. They often lack physical exercise and conversational objects, resulting in poor physical and mental health, such as the possibility of dementia in the elderly, or loneliness and depression. If you can play games and cross-links through online sports games, especially through the technology of the present invention, the physical and mental health of the players will be greatly improved. The way to play and cross-link can be diversified, such as surfing the Internet via a mobile phone or using a fitness equipment network at home. If necessary, the user can shoot their own action video files, and then make them as GIF. Basically, at least four face-oriented shootings are uploaded to the central control server to replace the virtual characters, so that other participants can play together face to face. Realism. In this way, the user can play games in sports, or can play in the game, and can also make friends and contact feelings. For example, the real sports version of Happy Farm: Figure 9 shows the control flow chart of the sports game of the present invention. The user opens 20 sports games--Happy Farm, which can be a real shot of a farm in Taiwan or China, or a virtual farm. pasture. The home form 21 presents banks, shops, markets, farms, etc., and farms can provide multiple stations: for example, vegetable gardens, chicken farms, pig farms, cattle farms, sheep farms, etc., users must go to the sports game setting 22- 23 to carry out various settings, such as the need to use fitness equipment, let the agent virtual characters walk in the happy farm, whether to play this sports game with others; how much money to prepare to manage the area and type. After the setting is completed, you can play sports games 24-25. The user interface: there is a map of the whole farm, the farmhouse of the user, the warehouse, the tool room, etc., and the routine is carried out every day by using the fitness equipment to complete the routine. Work, for example, the vegetable garden should regularly remove grass, fertilize, sow, water, catch insects, harvest, turn soil, etc., in order to have a good harvest. Chicken farms must feed the feed regularly, collect eggs, clean, inject vaccines, etc., and the chickens can only breed. Cattle farms must regularly harvest grass, milk, etc. In addition, this sports game will display various difficulties and conditions. 26 For example, after the feed is finished, the eggs are waiting for the pig, the pig is sick, some people come to visit, some people break into the farm, etc., the user must go to the treatment 27 quickly, and can solve or request others by themselves. Assistance 28. The size of the farm and the size of the farm, the type of crop planted, the number and type of animals to be farmed must be determined based on the amount of investment. Awards or points are determined in accordance with the tokens sold in the harvest. Of course, high scores must mean that the effect of exercise is good, effectively improving the fun and willingness of people's sports.

In addition to the above user interface, a full range of pastoral aerial GPS is also provided. Figure, the location of the patrol or other people or patrol dogs on the GPS aerial map, allowing users to dodge. In addition, animals such as chickens, cows, pigs, sheep, dogs, cats, etc. can be made into GIF photo files. In particular, you can make your favorite pets into GIF photo files and put them on the real scene of Happy Farm. interactive. The operation of Happy Farms can be achieved through cooperation with many people. Therefore, friends of the elderly can come together to exercise and let the happy farms have a good income. You can play together with multiple teams to add more fun.
