Other Abstract提出一种在复杂背景条件下,使用双目立体视觉近距离测量导线局部三维位置信息的方法.利用导线在视野中的连续性和平滑性,首先在图像中部选择与图像等宽的区域,使用基于稀疏Census变换和直方图匹配的方法把导线区域分割出来.然后只在临近已知导线区域的其他部分分割出导线区域.最后使用Canny算子和Hough变换获得导线边沿函数并计算导线的三维信息.实验结果表明:算法在复杂背景下能够准确获得导线双边沿,测量结果与实际导线宽度非常接近。; In this paper, a method of measuring the local three-dimensional position information of a wire using binocular stereo vision is proposed under the condition of complex background, which uses the continuity and smoothness of the wire in the field of vision. First, the region is selected in the middle of the image and the image is equal to the image in the middle of the image. The method of sparse Census transform and histogram matching is used to divide the traverse area out. Then, the traverse region is divided only in the other parts of the known traverse area. Finally, the Canny operator and Hough transform are used to obtain the traverse edge function and calculate the three-dimensional information of the wire. The experimental results show that the algorithm can accurately obtain the double edge of the wire in the complex background, and the measurement results are very close to the actual wire width.
