BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a traffic information processing system, and more particularly, to a traffic information processing system that provides a simulated image and speed information to a mobile terminal by producing a simulated image of a site for determining a traffic condition.

Traffic information generally provided includes radio traffic information through a communication operator and TV traffic information using image information.

However, the traffic information of the radio and TV is difficult to allow the driver to avoid the congestion section by preparing the driving plan in advance by receiving the information of the desired place at the desired time in advance.

And, the video information of the traffic information that can be provided in various forms is mainly provided through the web or TV using the wired Internet.

Therefore, it is difficult to provide information unless there is an environment for accessing the web or TV, and in the case of TV, the information is available only at a certain time of a specific program. .

In addition, although the speed information for each section is provided in the form of text using the wireless Internet of the mobile terminal, it is difficult for the driver to accurately grasp the traffic flow.

In order to solve the above problems, an object of the present invention is to produce a simulated image suitable for a mobile terminal and to provide a simulated image and speed information as traffic information.

Another object of the present invention is to provide traffic information to more people by providing simulated images and speed as traffic information to a mobile terminal using a widely used wireless Internet.

Another object of the present invention is to reduce traffic congestion by using more traffic information for more people.

The present invention provides an image providing means for providing traffic image information of a field, an image receiving server for receiving image information from the image providing means, and the image receiving server in order to provide an image suitable for a mobile terminal as traffic information. Image database in which the image information is stored in real time, a simulation image generator for generating a simulation image suitable for a mobile terminal using the image of the image database, a simulation image database in which the simulation image generated by the simulation image generator is stored, the image database And a service server for extracting velocity information by processing the image and providing the simulated image of the simulated image database to the mobile terminal through the wireless Internet together with the velocity information.

Hereinafter, exemplary embodiments will be described in more detail with reference to the accompanying drawings.

Traffic information processing system according to an embodiment of the present invention, as shown in FIG. 1, has a CCTV (2) and the information provider (4) as a means for providing traffic video information, CCTV (2) and information provider (4) An image receiving server 6 storing the image information received from the image database 8 and a simulated image suitable for the mobile terminal 16 are generated in advance by using the image of the image database 8 and the simulated image database 14. Extracts the velocity information by processing the images of the simulated image generator 12 and the image database 8 to be stored in the mobile terminal 16 together with the velocity information. It is provided with a service server 10 to provide.

The traffic information processing system having the above configuration is first installed in a predetermined place, and the traffic video information through the Internet network and dedicated line from the CCTV (2) to take the traffic flow and the information provider (4) to collect and provide the traffic information To be provided.

The traffic image information is real time image information including location information and time information, and the image receiving server 6 receiving the traffic image information displays all received image information as a real time video or a still image of a predetermined frame number. Stored in the database (8).

Then, the simulated image generator 12 generates a simulated image suitable for the mobile terminal 16 by using the image information stored in the image database 8 and stores the simulated image in the simulated image database 14.

As described above, generating a simulated image suitable for the mobile terminal 16 in the simulated image generator 12 may provide a display size of the mobile terminal 16 to provide traffic image information to the mobile terminal 16 through the wireless Internet. The communication speed of the mobile communication network, the size of the image that the mobile terminal 16 can accommodate, the color that the mobile terminal 16 can express, and the technology used to express the image in the mobile terminal 16 (eg For example, there are various restrictions, such as Wireless Application Protocol (WAP), General Virtual Machine (GVM), Java, Wavelet, Moving Picture Experts Group (MPEG), etc.).

That is, since there is a limit in providing information by processing an image in real time to the mobile terminal 16, and the discrimination power of the image information is reduced according to the model of the mobile terminal 16, the simulated image generator 12 actually Creates a simulated image with reduced data volume by adjusting resolution, color and size.

Such a simulated image is generated for each vehicle speed according to each position based on the image stored in the image database 8.

For example, the vehicle speed is distinguished by 20 km / h, 30 km, 40 km, 50 km, 60 km or more, and a simulated image is generated for each speed, wherein the simulated image is not a general video but 3 to 5 images. It consists of still image frames and shows each frame sequentially to make the image look like a video.

This simulated image uses the principle that the object in the image seems to move and the speed is different according to the transmission period when each frame is sequentially transmitted. In order to generate an image optimized for the mobile terminal 16, Backgrounds that are not related to the flow are simplified, and cars in the centerline, lanes, and distant cars are imaged to be easily distinguished.

More specifically, as shown in FIG. 2, the vehicle is shown to move by sequentially showing a plurality of frames having no change in the background and only the position of the vehicle.

As described above, in order to make a simulated image composed of a plurality of frames look like a video at a corresponding speed, a period in which each frame is transmitted must be different.

That is, as shown in FIG. 3, when each frame corresponding to the period T is sequentially transmitted at 20 km per hour, each frame corresponding to the period T / 2 is sequentially transmitted at 40 km per hour and 60 km per hour. In this case, each frame corresponding to the period T / 3 is sequentially transmitted.

In other words, a simulated image composed of a plurality of frames is generated for each speed, and when providing the simulated image to the mobile terminal 16, each frame is sequentially provided according to a frame transmission period corresponding to the corresponding speed.

In addition, the simulated image is separately generated with 256 color, 4-gray color, and black / white color image according to the color supported by the mobile terminal 16.

The simulated image generated as described above is generated and stored in advance before the traffic information providing service is performed. The simulated image is generated considering the place, time, weather, and the like. Is generated.

The generated simulated image is provided to the mobile terminal 16 through the wireless Internet network when the user requests information using the mobile terminal 16.

The wireless internet network here is a combination of an internet network and a wireless communication network, collectively encompassing a network connecting a wireless terminal and an internet connection device.

At this time, when the user requests the traffic information of the desired place, the service server 10 finds the speed information by processing the image based on the image information most recently received from the image database 8 for the place.

In this case, the image processing refers to obtaining a speed by using an object moving distance in an image with respect to time by using the time when the image information is received.

Thus, the service server 10 reads the simulated image of the obtained speed information from the simulated image database 14, converts it into an image form suitable for the mobile terminal, and provides it to the mobile terminal 16.

As shown in FIG. 4, the image provided to the mobile terminal 16 is represented by the caption type text along with the image information.

5 shows a configuration of another embodiment according to the present invention, which includes a CCTV 22, an information provider 24, and a speed measuring device 26 for measuring and providing a speed for providing traffic image information. And an image / speed receiving server 28 for storing the image and speed information received from the information provider 24 and the speed measurer 26 in the image / speed database 30, and the image / speed database 30. Velocity information of the simulated image generator 34 and the image / velocity database 30, which generate a simulated image suitable for the mobile terminal 38 in advance using the image of the image, and store it in the simulated image database 36, and a simulation suitable for the corresponding speed. It is provided with a service server 32 for providing a simulated image of the image database 36 to the mobile terminal 38.

First, the traffic image information is provided from the CCTV 22 and the information provider 24, and the speed information is provided to the speed measuring device 26.

Here, the speed meter 26 may be, for example, a speed gun.

The image information and the speed information are stored in real time including the location information and time information in the image / speed database 30 by the image / speed reception server 28.

Descriptions of functions and operations of the simulated image generator 34 and the simulated image database 36 are the same as those of the exemplary embodiment of the present invention, and thus descriptions thereof will be omitted.

Thus, when the mobile terminal 38 requests the traffic information of a specific place, the service server 32 finds the most recent speed information of the place from the image / speed database 30 and simulates the image. It is retrieved from the simulated image database 36 and converted into an image form suitable for the format of the mobile terminal 38 to be provided.

As described above, the present invention has an effect of allowing the driver to easily and accurately grasp the traffic flow state by providing the optimized image and the speed information to the mobile terminal.

In addition, by providing a simulated image and speed as traffic information to a mobile terminal using a widely used wireless Internet, more people can use traffic information.

In addition, more people use traffic information to reduce traffic congestion.
