3-D Navigation System on Golf Ball Flight by High VisionCamera Images

高尔夫球飞行的三维轨迹（X， Y， Z）由高清摄像机图像捕捉。通过安装在摄像机平台上的旋转编码器的脉冲信号检测摄像机的各个方向和变焦信号。利用图像处理软件对电视显示的球的位置信息进行分析。将这些信息整合后，我们可以得到高尔夫球在每一个时间步长t的位置（X， Y， Z）。至此，我们已经完成了这些硬件和图像处理系统。该系统的一些改进正在进行现场测试。

The 3-D trajectories (X, Y, Z) of golf ball flight are captured by Hi-vision camera images. The signals of various directions and zooming of the camera are detected by the pulse signals of rotary-encoder, which mounted on camera platform. The position information of the ball on TV display is analyzed by image processing software. After integration of the information, we can get the golf ball position (X, Y, Z) in every time step t. Now, we had completed these hard wares and image processing system. Some refinements of the system are conducting on the field testing.
