Research on Weld Visual Tracking Algorithm Based on LabVIEW

工件在焊接时的自动化要求越来越高,为提高焊接机器人应用时的智能化水平,提出了基于LabVIEW的焊缝视觉跟踪算法,该算法是使用模板匹配法对结构光图像进行识别,用计算机测算出V型焊缝所在坐标位置。结合跟踪算法进行了实验平台的搭设测试,利用LabVIEW进行编程,编程界面友好,且图形化的编程效率较高。实验结果表明:图像识别坐标与实测坐标进行比较,有较高的准确性和一致性。

In order to improve the intellectualization level of welding robot application,a welding seam visual tracking algorithm based on LabVIEW was proposed,which used template matching method to identify the structure light image,and used the computer to calculate the coordinate position of v-shaped welding seam.The experimental platform was set up and tested with the tracking algorithm.The LabVIEW were used for programming.The programming interface was friendly and the graphical programming efficiency was high.The experiment results show that the image recognition coordinates are more accurate and consistent than the measured coordinates.
