摘要
介绍了用摄像机和计算机记录 3维物体运动的实验方法 ,以及实验中的关键环节 :对系统定标和确定时间坐标起点 .用这种方法研究了球面摆的运动规律 。
A moving object in 3 dimentiona1 space is recorded using video cameras and computers. There are two key steps in the experiments: determining the scaling factor for the system and the starting point of time. Spherical pendulum is studied using our scheme. The experimental results show the agreements with theory.
