The acoustic sensor in the present invention is an ultrasonic sensor, which can effectively eliminate the interference of human noise.

In this embodiment, the computer executes the process shown in FIG. 6 according to the content of the data processing software system: first perform data acquisition, then perform data filtering, and then determine whether the acquired signal is a real signal, and if not, repeat the above data In the collection step, if relevant, t2, t3, and t4 are obtained by correlation processing, and then whether t2, t3, and t4 meet the relevant constraint conditions, and if not, then return to the data collection step. If yes, then t2, t3, and t4 Substitute a specific formula to find the coordinates of the hit point (or hit point), y). With the above method, the coordinates of the hit point and the hit point can be obtained, and the computer can calculate the trajectory of the ball, and then instruct the large-screen projector 15 to play the corresponding simulation picture.

― 9-can be designed according to the actual situation. Generally, artificial intelligence technology should be used, which is the existing technology.

Figure 7 shows the structure of an impact-resistant curtain, which is composed of a front wall 1111 felt and a back sponge 1112, wherein the sponge is a buffer layer.

Since the present invention uses an ultrasonic sensor, a filter circuit, and whether or not the acquired signal is a true signal to judge, it can ideally exclude interference of various noises, thereby more accurately positioning the hit point and the hitting point.

B) Simulation laser shooting system

The simulated laser shooting system shown in FIG. 8 includes a laser gun (not shown), a high-definition display 71, a camera 77, a capture card 78, a main control computer 72, and an audio device 76. The main control computer 72 contains The laser point measurement software system 79 and the main control software system 74, the main control computer 72 controls the audio device 76 and controls the high-definition display 71 through the internal main control software system 74; the above: fNie image head 77, capture card measuring the laser spot ₇₈ and 79 constituting the software system of the laser spot measurement system; the camera 77 can be placed in the intake position of the image display high-definition display 71, whose output is connected preclude the set input terminal 78 of the card, The output end of the acquisition card 78 is connected to the laser point measurement software system 79 in the main control computer 72. The laser point measurement software system 79 is connected to the main control software system 74. The main control computer 72 is connected to the Internet 710 through the network interconnection device 73. The Internet 710 and Other simulated laser shooting systems 75 are connected.

In this embodiment, the high-definition display 71 is used to display a computer-generated picture and is also used as a target of a laser gun; the laser gun is used to display the high-definition display 71 The laser is emitted; the laser point measurement system is used to measure the position coordinates of the laser point on the screen, wherein the camera 77 converts the image from the screen and the light signal of the laser point into electrical signals, and the acquisition card 78 The signal is converted into a digital signal stored by frame, and the gray value of each pixel of a frame is determined; the laser point measurement software system 79 is used to find the point with the largest gray value and determine whether it is a laser point. If so, Find the position coordinates relative to the screen; the main control software system 74 is used to generate dynamic pictures, control the playback of the audio equipment, and compare the position coordinates of the laser point transmitted from the laser point measurement system with the target position to determine whether to hit If it hits the target, it will switch to dynamic pictures such as animals falling, airplanes, warships firing or exploding, while also scoring, ranking, and controlling network interconnection equipment to achieve network battles; audio equipment 75 is controlled by the host control software system , Play the sound of gunfire, and various sounds of animals, aircraft roar, etc.

The working principle of the laser spot measurement system in this system is as follows: Use the camera to align the image and laser spot on the screen. Since the brightness of the laser spot is much greater than the brightness of the image, when the aperture of the camera is adjusted to a sufficiently small value, it can make the Only the laser points with gray values greater than a certain value a (0 <a <256, generally taken as 230) in the image acquired by the camera, and the gray values of other points are less than a. In this way, by determining the gray value in the software, the pixel point corresponding to the laser point of 4 bar can be distinguished from other points. At this time, the position coordinates of the corresponding pixel of the laser point in the frame collected by the capture card can be obtained. Then, the position coordinates of the laser point relative to the screen can be obtained through a certain transformation in the software.

In the software system, the functions of the acquisition card are used to obtain the current frame images. The gray level information of the point, and then use the circular judgment method to find the point with the largest gray value first, and determine whether the gray value of the point is greater than a certain value (such as 230). If it is greater than this value, it indicates that the gray level is the largest. The pixel corresponding to the value is the pixel where the laser point is located, not the interference caused by the projection of other rays on the screen (because the gray value of the pixel point corresponding to the projection of other rays on the screen will not be greater than this value). At this time, the position coordinates of the pixel in the image taken by the camera can be obtained at the same time, and the position coordinates on the screen can be obtained through another transformation. The transformation factors required for this transformation are obtained by calibrating the laser point measurement system before first use. After the calibration is completed, as long as the camera position is kept unchanged, the conversion factor will not change, and there is no need to recalibrate the laser point measurement system in the future.

The main control software system executes the flow shown in FIG. 9: first generate a new animation frame when the target is not hit, and then collect the image signal processed by the laser point measurement software system to determine whether there are laser points in the image. If not, go back to the step of generating a new animation frame when the target is not hit, and if so, determine whether the laser dot hits the target. If not, return to the new animation when the target is not hit. The frame steps are scored at the same time. If so, the new animation frame after the target is hit is scored.

The computers in the above two games can be the scoring computers of the bowling alleys, and both can be connected to the network to play online games.

It should be noted that, for those skilled in the art, without departing from the principle of the present invention, several improvements or variations can be made to the system, and these improvements or variations should be regarded as belonging to the protection scope of the present invention.
