摘　　要：提出了一种基于光编码技术深度传感器的埋弧焊焊缝检测方法,提高了埋弧焊焊缝的检测速度与准确度以及抗干扰能力。通过对埋弧焊焊缝空间特征以及深度传感器采集的图像数据分析,确定深度图像中深度值最大的点即为焊缝中心处。根据这一特征给出了确定埋弧焊焊缝中心的一种快速算法,计算寻找图像中每行像素深度值最大的点,并根据这些点来确定焊缝的中心位置。这种检测方法对图像预处理要求低,计算速度快并且对光源无要求。试验表明:该方法准确、快速、稳定并且抗干扰能力强。In order to improve the detection speed,accuracy and anti-jamming capability of submerged arc welding,a detection method based on the light coding technology depth sensor had been put forward.After the analysis from the spatial characteristics of submerged arc welding seam and the depth image data,the center of the weld was determined by the maximum point of the depth value in depth image.This feature showed a fast algorithm to determine submerged arc weld center,to determine the weld center position by find the maximum point of the depth value each line of pixels in the depth image.This detection method had low image pre-processing requirements,fast calculation speed and it required nothing to the light source.The experiments showed that this method was accurate,fast,stable and strong anti-interference ability.
