Research And Implementation Of Virtual Golf System

Virtual reality technology is a across-disciplinary which combined computer graphics technology, simulation technology and other subjects it has a wide range of applications in various fields. Virtual golf system is generated by the combination of virtual reality technology and golf sports.Virtual golf system combines many studies hot spots of virtual reality technology, such as visual parameter measurement, real-time rendering, physics simulation technology. Therefore, The main work is as follows:First, this paper studies the real-time computational algorithms of moving target trajectory parameters based on high-speed stereo vision.To achieve a non-parallel binocular stereo vision based real-time calculation of three-dimensional high-speed moving target trajectory parameters. The system requires high-speed acquisition of image data for real-time processing. By target detection, real-time distortion correction and three-dimensional computation algorithm,the system obtains the target trajectory point coordinates, and then calculate the motion parameters. High-speed image data real-time processing and the accuracy of image data processing results is the key point of the vision-based measurement system.Finally, based on the study and research, this paper has developed a virtual golf measurement system, the system can calculate the trajectory parameters of golf real-time.Secondly, this paper studied the key technologies of using graphics engine, physics engine for the development of virtual reality application.For a complete virtual reality simulation system,not only need to use three-dimensional graphics technology for real-time scene rendering, but also need to simulate the real physical world, accurate physics calculations. Finally, this paper uses OpenSceneGraph3D graphics engine, physics engine Bullet and ocean scene rendering library OsgOcean, developed real-time rendering of virtual golf system.Finally,based on the studies above,a stereo vision-based high-speed moving target parameter measurement system and real-time rendering simulation systems is developed, and through the validation experiments,the virtual golf system is built.
