This paper presents a work-piece position correction equipment. In order to correct work-piece position, for using video
signal, this paper illustrates the method of similarity rate of labelled images to carry on object location and to calculate
work-piece's deviate angle. This method is proved to be useful and efficient in testing. This paper is new and original in
three facts. First, using similarity rate of labelled image is more convenient for this purpose than the complex
combination of sensors and machinery. Second, the algorithm of this method is easier to realize than other methods.
Third, this equipment can fit a multi-purpose situation through flexible adjusting matching labelled image. This method
in the paper can be widely used in other similar application.
