摘　　要：介绍一种用于虚拟现实环境中的摄像机跟踪系统,给出了系统的软硬件设计方案及控制策略。该系统采用改进的Hough变换来检测辅助摄像头获取的光源阵列中的椭圆图形,通过对椭圆图形运动的跟踪,计算出其相对于初始位置的偏移,实现对虚拟现实环境中的摄像机状态参数的获取和定位。试验结果表明该跟踪系统可以满足虚拟现实环境中的摄像机跟踪任务,在实际环境中取得了良好的跟踪效果。A camera tracking system used in virtual reality environment is described,design and control strategy of the system software and hardware are given.The improved Hough transform is used to detect the elliptical pattern of the light source array obtained by the auxiliary camera.By the tracking of the elliptical pattern movement, the offset for the initial position is calculated,the acquisition and positioning of the camera status parameters in the virtual reality environment are realized.The test results show that the tracking system can meet the camera tracking task in the virtual reality environment,and achieve good tracking results in real environment.
