Shotgun photoelectric positioning of the optical system hardware and software design

Shotgun photoelectric positioning technology is a key technology of virtual reality training system for clay target shooter. It was used to detect the 3D spatial attitude of the shotgun. To realize the testing of spatial attitude of shotgun the combinative methods of simulating gun, high-speed camera, and double beam splitting thin films are used, then to obtain gun´s 3D coordinates the calculation is performed by means of the light spot center position solved by MATLAB software and the model established by the optical system. Consequently the problems of low measurement accuracy, narrow range and sensitive to magnetic fields are solved.
