【摘要】 为达到非接触式测量的目的,采用机器视觉的方法来实现对运动机构的运动参数的测定。通过在机构上设定一个标志,利用模板匹配技术,对该目标实现实时在线跟踪,得到它在动态图像中每次的坐标值,通过对动态图像的分析和处理从而在线得到各种运动参数的曲线。模板匹配算法采用了全局匹配与小区域匹配相结合的策略。小区域匹配一次所用时间为20 ms,完全能达到在线实时跟踪测试的要求。更多还原

【Abstract】 The purpose of this paper is using the method of machine vision to measure the motion parameter of motion framework,consequently get the purpose of non-touching measure.By setting a sing on the framework and using pattern template matching technique to achieve the online real-time track of the sign and get the coordinate of the dynamic image of the sign.By analyzing and handling the dynamic image,get curves of several motion parameters.Pattern matching arithmetic adopts a method of combining global match and small-region match.Each time,the small-region match spend 20 ms,which can achieve the require of online real-time tracking test.更多还原
