摘　　要：采用Labview虚拟平台、Matlab节点、三维控件实现对数据的计算处理和三维场景的构建;通过量子粒子群优化算法对摄像机精确标定并对拍摄图像进行去噪处理得到离散中心点,三维匹配获得对应的三维坐标,通过高斯拟合获取平滑曲线轨迹;根据拟合曲线完成虚拟网球场景搭建、网球运行轨迹回放以及判定.通过检测表明该系统计算量合理,判定的正确率高于92%.The Labview virtual plafform,Matlab nodes and three-dimensional control are used to achieve calculation and processing of data and build three-dimensional scene. We calibrate camera accurately by Quantum Particle Swarm Optimization Algorithm, get discrete center by denoising and achieve three-dimensional coordinates by three- dimensional matching, obtain a smooth curve by Gaussian fitting. According to fitting curve, we accomplish the build of virtual tennis scene, the running track playback of tennis and the judgement of whether tennis is out of line. By detecting that the system is a reasonable amount of computation and the determine correct rate is higher than 92%.
