【摘要】 利用镜面反射原理,设置多个镜面,把截面形状为多边形的管子的每一个棱侧面成像到对应一个镜面中。利用相机拍摄镜面中的图像,一次性获取多个管壁棱侧面图像。调整镜面与管壁之间平面角呈45度,可以在镜面中获取清晰图像。通过一个位移传感器,实现在管子转动过程中让管子转正姿态的一种方法。在此基础上调用Halcon图像处理库,对拍摄到的图像进行处理,实现焊缝位置的成功检测,检测成功率在95%以上。更多还原

【Abstract】 Based on the principle of mirror reflection, a number of mirrors were set up to image each edge and side of a tube with a polygon cross-section into a corresponding mirror. Using the camera to take the image in the mirror, the side image of multiple tube wall edges could be obtained at one time. By adjusting the plane angle between the mirror and the tube wall to 45 degrees, a clear image could be obtained in the mirror. We realized a method to make the tube turn to the right position through a displacement sensor in the course of the tube rotation. On this basis, we called the Halcon image processing library to process the captured image, and realized the successful detection of the weld position. The detection success rate is more than 95%.更多还原
