Abstract

Airborne laser technology is widely used in transmission line operation and maintenance line construction acceptance and tree barrier analysis, and transmission line point cloud extraction is the basic work of these applications. A wire point cloud extraction algorithm is proposed in this paper. The first step is to segment the original point cloud data of a sortie by file; the second step is to roughly classify the single point cloud data; the third step is to refine the wire point cloud to obtain the target wire point cloud. Experiments verify that the accuracy of the algorithm is 90.2%, which verifies the accuracy and applicability of this algorithm.
