摘要
针对传统汽车漆面维修以人工为主,存在劳动强度高、效率低、一致性差等问题,结合人工打磨经验,在提取受损车面轮廓的基础上,设计生成受损车面维修打磨区域算法.首先,综合运用边缘检测算子、曲线近似算法对受损漆面进行轮廓提取.然后,运用凸包算法预生成轮廓,再对轮廓改进生成最终车面维修打磨区域.通过比较人工和算法生成后的打磨区域可知,算法生成的打磨区域精度较高,可满足基本打磨要求,该算法为实现自动化打磨提供了理论依据.
In a traditional industry,automotive paint repair is dominated by manual labor,which has problems such as high labor intensity,low efficiency and poor consistency.Combining the experience of manual sanding,the algorithm of generating the damaged car surface repair sanding area was designed based on the extraction of the damaged car surface contour.Firstly,the edge detection operator and convex hull algorithm were used to extract the contour of the damaged paint surface,then the convex package algorithm was used to pre-generate the contour,and then the contour was improved to generate the final car surface repair sanding area.By comparing the actual manual sanding area and the algorithm-generated sanding area,it shows that the sanding area generated by the algorithm is more accurate and meets the basic sanding requirements,which can provide a theoretical basis for the realization of automated sanding.
