Embodiment Construction

[0045] The technical solution of the present invention is further described below, but the scope of protection is not limited to the description.

[0046] A multi-model power line segmentation method provided by the present invention mainly studies two power line models of model A and model B. The two models have obvious distinguishing features in the XOY plane and XYZ space. Therefore, the power line model can be identified according to the distinguishing features , a multi-model power line segmentation method comprising the following steps:

[0047] ① Model judgment: divide the power line into several segments along the direction of the power line and the empirical step length, cluster each segment in the XOY plane and XYZ space, and determine the power line model A according to the statistical results of the two clusters in each segment and model B;

[0048]②Segment the power lines of model A: segment the power lines on the XOY plane, perform clustering, and count the clus...

Abstract

The invention provides a multi-model power line segmentation method. The multi-model power line segmentation method comprises the following steps of model judgment, power line segmentation of a modelA and power line segmentation of a model B. According to the method, the number of the power lines is obtained by adopting a power line point cloud local statistics mode, a complete point cloud segment can be obtained for an XOY surface projection non-coincidence model, and the loss of multiple positions of the power lines is avoided. Aiming at an XOY plane projection coincidence model, a completepoint cloud segment elevation sorting mode is adopted, elevation sorting is carried out on segments without missing point cloud, and then proximity matching is carried out on the missing segments, sothat the influence on power line segmentation due to multi-position missing of power line point cloud is solved.

Description

technical field [0001] The invention relates to a multi-model power line segmentation method, which belongs to the technical field of multi-model power line segmentation under the condition of lack of point clouds. Background technique [0002] In recent years, airborne LiDAR (light detection and ranging) has been widely used in the inspection of transmission lines. Its high efficiency, accuracy, and real-time characteristics have been widely favored by the power industry, and the operation and maintenance of transmission lines has also entered digital operation. and the era of intelligent management. [0003] Power line point cloud segmentation is one of the important tasks of airborne laser radar (LiDAR) power line inspection. There are still some problems in the current research on power line segmentation algorithms, which can be summarized as follows: 1. Mainly study the relatively complete point cloud of power lines, Insufficient research on point cloud segmentation of...
