Abstract

The invention relates to a toy/game gun, in particular to a method for calculating the shooting effect of the toy/game gun, which comprises that a spatial sensor is arranged on the game gun, and specific spatial coordinates of the game gun are acquired and calculated in real time through a high-performance CPU. When a user pulls a trigger, a system calculates the droppoints and routes of bullets according to a shooting line from a gun breech to a gun head and the shoot range of the game gun; and if the routes of the bullets are intersected with a target, the system hits the target, and if the routes of the bullets are not intersected with the target, the system does not hit the target. The shooting effect can be calculated easily regardless of points, planes or three-dimensional objects. By the method, the problem that most of toy/game guns cannot shoot indeed in the markets can be solved, and the toy/game gun is wide in application range, safe, reliable and unlimited in shooting targets.

Description

The computational methods of spatial orientation toy gun and a kind of shooting effect of toy gun

Technical field

The present invention relates to the computational methods of toy rifle, particularly shooting effect of toy gun.

Background technology

Along with the rapid raising of people's levels of substance, peashooter is universal greatly, and each boy as a child had one peashooter in the city basically.But most peashooters are an appearance, do not have real shooting function.The toy rifle that the shooting function can really be finished in present market has only three classes basically:

One, infrared ray peashooter.This rifle is to utilize ultrared emission and accept to judge whether to hit target.Just an infrared transmitting tube, an infrared receiving tube.Transmit when adopter receives, be and hit the mark, otherwise be miss.Just goal can only be point of infrared receiving tube, and can not form a face.Accept face if make one with infrared technology, cost will be quite expensive.

Two, street machine light plinker, the principle of this rifle be utilize PAL the screen scanning principle of CRT monitor of NTSC, send the signal of detecing of a CF by the software command display, showing can be in order from left to right, on each aspect of screen, launch this signal successively from top to bottom, the optical receiving set of particular frequencies is housed on the rifle.Begin to send by calculation display and detect time difference that signal and rifle receive signal and calculate rifle and received transmitting of that point on the screen, just hit which target.But this technology can only be applied in the display based on CRT, and in today that LCD is now popularized on a large scale, except machine market, street, this principle plinker has no idea to enter household game market.

Three, paintball gun, though this rifle and true rifle are very similar, though aspect feel and gripping, paintball gun and true rifle are not quite similar.And paintball has injury effect to the people.So our country has put into effect the regulation that paintball gun is managed specially, and paintball gun has been carried out strict restriction.

As can be seen from the above, also do not have on the market on the family expenses toy rifle now a kind of product and technology can under situation about being perfectly safe, make peashooter real have a complete shooting function.

Summary of the invention

The computational methods that the purpose of this invention is to provide a kind of spatial orientation toy gun and a kind of shooting effect of toy gun.Peashooter can be realized to all types of target by this peashooter and method,, and the effect of shooting can be accurately calculated as computer screen, people's etc. shooting.

The present invention is achieved in that

Two space orientation sensors (gyroscope or acceleration transducer etc.) are installed on the head and tail of rifle.If target is a moving target, then target is also installed one or more space orientation sensors.If target is a fixed target, then do not need.

A high performance CPU is arranged in the system, the real-time data of pick-up transducers, and calculate the space coordinates of each sensor.When user's cocking, system calculates the drop point and the stroke of bullet according to the range region of course from gun breech to the rifle head and rifle, and system hits the mark if bullet stroke and target are crossing, if non-intersect, does not then hit.No matter target is point, plane or three-dimensional thing, can calculate easily.

By technique scheme, the technique effect that the present invention has is:

Can solve the problem that most of on the market toy rifles can not really be shot by this method, and have wide range of applications, safe and reliable, can very accurate simulation and emulation to fire effect, goal is unrestricted.

Description of drawings

Fig. 1 calculates the schematic diagram of fire effect for using this method.

(X1, Y1 is Z1) for being installed in the locus coordinate of the sensor 1 on the rifle.

(X2, Y2 is Z2) for being installed in the locus coordinate of the sensor 2 on the rifle.

(X3, Y3, Z3) for the bullet that calculates the locus coordinate.

(Za～Zb) is the object space position coordinates for Xa～Xb, Ya～Yb.

Fig. 2 carries out initialized design sketch to system coordinates before using this method to begin.

The O point is the selected origin of coordinates of system.

The coordinate points of sensor 1 during (0,0,0) initialization.

The coordinate points of sensor 2 during (L1,0,0) initialization.

The coordinate points of target during (L2,0,0) initialization.

The specific embodiment

At first carry out initialization, rifle and target are placed on the position of a fixed range.The initialization sensor.If target is a fixed target, then simultaneously can calculate target direction.As shown in Figure 2, setting at 0 is system's original coordinates point, is that datum mark carries out all sensors of initialization so calculate with the O point.The initial coordinate of two sensors is (0,0,0) and (L1,0,0) on the rifle.If target is a fixed target, then (L2,0,0) is a basic point grid bearing of target; If target is a moving target, the initial coordinate point of (L2,0,0) sensor of interest then.Utilize the origin coordinates point can calculate the positional information X of sensor, Y, Z accurately.

If target is three-dimensional target, then can be with the prior input system of the size of target, also can utilize sensor on the rifle to calculate the size of target.

Recreation beginning then, the high-performance CPU in the system gathers and calculates the data of sensor in real time.Obtain the space multistory coordinate (X1 of rifle head and gun breech, Y1, Z1) and (X2, Y2, Z2), when user's cocking, as shown in Figure 1, (whether Xa～Xb, Ya～Yb, the input CPU of Za～Zb) calculate according to following formula and to hit the mark with the three-dimensional coordinate (X1, Y1, Z1) (X2, Y2, Z2) of two sensors of pistol and the space coordinates of target.

Formula 1:(X1-X2)/(X3-X1)=(Y1-Y2)/(Y3-Y1)

Formula 1:(X1-X2)/(X3-X1)=(Z1-Z2)/(Z3-Z1)

Xa＜X3 when Za＜Z3＜zb＜Xb simultaneously Ya＜Y3＜Yb and

(Z3-Z1) ²+(Y3-Y1) ²+(X3-X1) ²＜Len ²

Len is the range of rifle. then system hits the mark.Otherwise system does not hit the mark.

Simultaneously can according to formula 1 and formula 2 calculate bullet distribution situation (X3, Y3, Z3).

Being preferred embodiment of the present invention only in sum, is not to be used for limiting practical range of the present invention.Be that all equivalences of doing according to the content of the present patent application claim change and modification, all should be technology category of the present invention.
