摘要
针对基于影像的电力线三维建模中,无法直接得到电力弧线上大量匹配序列点的问题,提出了一种基于多影像立体测量采样,悬链方程拟合的电力线建模方法。该方法首先利用线特征提取算子,实现了影像上电力线二维线段的提取;基于多影像核线几何关系,实现了电力线采样点的三维坐标计算;采用了架空线悬链方程,实现了电力线模型的建立。实验表明,该算法可以实现高度还原电力线的空间位置。
In the 3D modeling of power line based on image,to solve the problem that it can not directly obtain the large number of matching sequence points on the curve of power line,we propose a method of measurement sampling based on multiple images . a means of modeling by catenary power line equation. In this method,the linear feature extraction algorithm is used to extract the 2D line segment of the image,and the 3D coordinates of the sample points of the power line are calculated based on the geometric relationship of the multiple images. Experiments show that the proposed algorithm can achieve the space position of the power line highly reliably.
