摘要
基于线束包覆设备提出一种能够检测定位线束端点及分支点的图像处理方法。运用HALCON软件内的函数库对摄像机进行标定,使用Threshold、Skeleton等算子对线束端点及分叉点的坐标进行定位。通过坐标点获取线束各段长度,并通过坐标系转换得到世界坐标系下各点的坐标值,将计算值与实际值进行比对分析得到相对误差与绝对误差。测量结果显示:平均相对误差小于5%,平均绝对误差小于5mm。该图像处理结果满足线束加工工艺的要求。
Based on harness banding equipment, an image processing system that can detect and locate the ＇end points and branch points of harnesses is presented. The camera is calibrated by using the function library in HALCON software. The end points of harness and the points of bifurcation are located by using Threshold, Skeleton, and so on. The length of each segment of the harness is obtained by the coordinate point, and the measured value in the world coordinate system is obtained by the coordinate system. The relative value and the absolute error are obtained by comparing the calculated value with the actual value. The average relative error of the experimental measurements is less than 5% and the absolute error is less than 5mm on average. The image processing results can meet the requirements of wire harness processing technology.
