摘要/Abstract

摘要： 利用CCD图象传感器的线性积分成象特性,将数字图象处理技术与时间积分成象方法结合用于运动时间历程的光测分析.采用文中提出的方法,只需分别摄取被测物体上的发光标志点在静态下的图象和其在运动状态下的时间积分成象,即可确定该物体在曝光时间内的运动时间历程,并且可以直观地记录下被测物体的运动轨迹.实验表明该方法具有较高的测量精度,对测量设备和实验条件的要求也很宽松.

Abstract: Based upon the linear integral imaging mechanism of the CCD image sensor, this paper presents a new method for measuring the motion of a moving object. By this new method, for determining the motion of a rigid body, only two time integral pictures are captured for a LED attached onto the surface of the body; the first picture was recorded when the body was in static state and the second picture was captured when the body was in motion. Experimental results have shown that the method can be used to determine displace -time and velocity -time functions of a moving object with reasonable accuracy. The method can also record the motion orbit of the moving object.

Key words: motion measurement, time-integral imaging, CCD solid state image sensor
