Description

Technical Field

[0001] The present invention relates to the technical field of simulated shooting, and in particular to a simulated shooting device for simulated shooting. Background Art

[0002] In the field of simulated shooting, simulated shooting devices that fire low-damage simulated bullets or lasers are often used in place of real weapons for simulation. While shooting with simulated bullets is safe to a certain extent, it still poses significant safety risks. As regulations restricting simulated weapons become increasingly stringent, many simulated shooting devices are no longer legally usable, significantly limiting civilian simulated shooting training or games. Laser simulated shooting devices, while safer, require participants to wear a vest covered with receivers. The sensors are not very accurate, making it difficult to determine if they have been hit by bullets in the limbs or lower body. Furthermore, the device is complex to wear and has limited application scenarios. Summary of the Invention

[0003] To achieve a safe and convenient simulated shooting device, the present invention implements a simulated shooting device based on posture estimation and ultra-wideband technology. An image capture device captures the image in front of the simulated shooting device, and a posture estimation program interprets the image content to analyze the position and posture of the person in front of the simulated shooting device. This is combined with the time the user pulls the trigger to determine the body part hit. Ultra-wideband technology's ability to measure distance and angle measures the angle formed by the line connecting the simulated shooting devices carried by both parties and the simulated shooting device's ray, as well as the distance between them, to comprehensively analyze whether the opponent was hit and the body part hit.

[0004] When the simulated trigger is triggered, the image capture device captures the image in the direction of the simulated gun's beam. A posture estimation and recognition program identifies the presence of a target object, as well as its position and posture within the image. An ultra-wideband radio positioning device identifies the target object in the beam's direction and, through a control program, determines whether the target was hit and the part of the target's body that was hit. A game control program determines the score, broadcasts an event message via a radio communication device, and then outputs the result via an audio and video output device. By integrating the simulation device into the simulated gun's housing, the device is portable and flexible. Leveraging radio communication technology, multiple simulated shooting devices can be used to implement a distributed or centralized simulated shooting system, enabling simulated shooting training and gaming in a variety of scenarios.

[0005] In order to fully understand the present invention, the present invention will be described in detail below. The accompanying drawings are only schematic diagrams and do not limit the present invention. In particular: An image capture device is installed in front of the simulated shooting device, and the image sensor plane is perpendicular to the ray, which is used to capture the image in front of the simulated shooting device; The pan / tilt platform at the rear of the simulated shooting device is used to adjust the angle of the image capture device to calibrate the rays of the simulated shooting device; Ultra-wideband equipment was used to measure angles and distances between multiple simulated shooting devices; The electronic computer is used to execute the control program of the simulated shooting process; Portable power supplies are used to provide energy for computers and peripherals.

[0006] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.

[0007] When the trigger device is triggered, the level of the input device changes and transmits a signal to the computer. The computer controls the image capture device to capture the picture in front of the simulated shooting device. The image capture device collects the picture and transmits it to the computer.

[0008] After the computer receives the front image returned by the image capture device, it will use the posture estimation program to analyze the image and determine whether there is a human body in the image. If there is a human body, it will continue to determine the position and posture of the human body in the image. The posture estimation program can quickly analyze the position and posture of one or more human bodies in the image, and determine whether there are any human body parts in the image that may be hit by a bullet.

[0009] After receiving the trigger device signal, the computer controls the ultra-wideband device to send radio signals and receive radio signals from other simulated shooting devices. By measuring the time it takes for the radio to arrive, the distance between the two simulated shooting devices is calculated. At the same time, the ultra-wideband device has two antennas with fixed distances. By measuring the phase difference of the radio signals received by the two antennas, the angle between the line connecting the two simulated shooting devices and the ray can be calculated. When the angle is less than a certain threshold, it is considered that the other party is in the range where it may be hit.

[0010] By comparing multiple objects that may be hit and their azimuth angles, as well as their distances from the current simulated shooting device, the object with the smallest angle between the line connecting the two and the ray, and which is not blocked in front by people belonging to other simulated shooting devices, is determined to be the target.

[0011] The simulated shooting device then broadcasts the identity of the person hit and the part of the body hit via radio. After receiving the broadcast information, other devices record the person being hit and deduct the corresponding points. When the elimination conditions are met, the simulated shooting device of the eliminated person will notify the eliminated person of the event result through the output device.

[0012] The above embodiments are only for illustrating the technical idea of ​​the present invention and cannot be used to limit the protection scope of the present invention. Any changes made on the basis of the technical solution in accordance with the technical idea proposed by the present invention shall fall within the protection scope of the present invention.
