【摘要】 介绍了SHJX系统──用摄像机对运动目标物摄像．利用微机的快速存储与处理数据的功能，从视频信号中提取物体的运动信息，实现实时采集；并就用数字滤波方法处理数据的结果作了讨论．此系统可对2个运动物体的信息同时进行采集和处理．在微机上显示运动物体的位移－时间、速度－时间、加速度－时间等模拟运动曲线．更多还原

【Abstract】 A method used to collect and process motion data by video camera and computer (SHJX) is described. The camera is focused to the motional objects and motion data are collectal from video view through special designed hardware and software in real time. The result processed by diagonal filter after collection is discussed. And the graphs of distance, velocity,and acceleration against time are displayed on screen. The information about the motional objects are also simulated on the screen.更多还原
