摘要

结合计算机辅助设计，提出了一种基于电子图纸的钣金件快速视觉定位方法。基于CAD俯视图获取钣金件边缘轮廓模板，同时搜索钣金图像金字塔进行模板匹配，提高了模板匹配速度。针对边缘不清晰或边缘不完整等问题，以内轮廓为模板，根据内轮廓的相对位置关系找到工件的中心点，得到钣金件取向的精确值。最后的实验验证了该方法的准确性和稳定性，误差在4mm以内，满足工业生产要求。

Rapid visual positioning of sheet metal parts based on electronic drawing templates

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.
