Abstract
A fast visual positioning of sheet metal parts based on electronic drawings is proposed in conjunction with CAD. The template of the edge contour of the sheet metal part is obtained based on the top view of CAD, and the sheet metal image pyramid is searched for template matching at the same time, thus improving the speed of template matching. For problems such as unclear edges or incomplete edges, the accurate value of the sheet metal part orientation is obtained by taking the inner contour as the template and finding the center point of the workpiece based on the relative position relationship of the inner contour. The final experiment verifies the accuracy and stability of the method, and the error is within 4mm, which meets the industrial production requirements.
