This paper presents a set of novel profiled strip parameter measurement equipment which is in serial production. In order to measure shape parameter, this paper designs the structure of equipment and illustrates method of image processing which carries on object location and shape parameter calculating work-piece for using machine vision. This method is proved to be useful and efficient in practice. This paper is innovative in four facts. First, it works using image processing which never appeared in such type of application. Similarly, the equipment can work no matter what directions that profiled strip lies. Third, the equipment can work automotive without man-made measurement error. Finally, it can be used to measure multi-kind of work-piece in the line. This method can be widely used in other similar application.
