Measurement of the parameter of the motion of the object , the conventional method is the use of the various displacement , speed and acceleration sensor. But how to determine the parameter of the motion of the object , according to the analysis of the image dynamic concept , currently receiving widespread attention . The goal of this paper is the use of machine vision to achieve the determination of the motion parameters of the moving bodies , so as to achieve the purpose of the non-contact measurement . Acquisition came in the movement of the image sequence using a CCD camera , in the program , set the timer , using template matching technique to implement a real-time online identification and tracking of the target set in motion mechanism , so as to get it coming in the CCD image sequence in each sampling time of the coordinate values. Adjacent coordinates of the target point value , using mathematical algorithms which line the parameters of the curve of the wide variety of sports . Template matching algorithm for the real-time requirements and characteristics of institutional continuity of the movement , a the global match small area match the combination of strategies . This makes the computation is greatly reduced, and to speed up the recognition speed , to achieve real-time tracking and recognition . Experimental test device of this article can be measured global match time 700ms, small regional local match once time is 20ms . Which can set the sampling interval of the timer is 30ms, can achieve the motion parameters online real-time test requirements .
