Point cloud data processing method and device

Abstract

The invention provides a point cloud data processing method and a point cloud data processing device. The method comprises the following steps: receiving first point cloud data acquired by a laser scanner; performing classification processing on the first point cloud data to acquire classified second point cloud data; if the second point cloud data at least comprises target point cloud data, judging whether the distance between other point cloud data in the second point cloud data and the target point cloud data is less than a first preset threshold value or not; and if the distance between other point cloud data in the second point cloud data and the target point cloud data is less than the first preset threshold value, determining other point cloud data as dangerous point cloud data. Through the point cloud data processing method and the point cloud data processing device, which are provided by the invention, artificial intervention components in the point cloud judgment process aregreatly reduced, the automation degree and the accuracy degree are relatively high, the cost is relatively low and the practicability is excellent.

Description

technical field [0001] The present invention relates to the technical field of lidar data processing, in particular to a point cloud data processing method and device. Background technique [0002] Transmission lines are an important part of the power grid. Quickly and efficiently inspecting the vegetation and other features near the power line has far-reaching significance for the power sector to realize real-time monitoring, rapid assessment and scientific prediction of the power system. [0003] With the development of lidar technology and UAV technology, UAVs are usually used to carry lidar scanning equipment to inspect transmission lines and obtain lidar point cloud data corresponding to transmission lines. Before troubleshooting the faults and hidden dangers of the transmission line through the laser radar point cloud data, it is first necessary to determine which laser radar point cloud data corresponds to the dangerous area of ​​the above transmission line. Accordin...

AI Technical Summary

Problems solved by technology

According to the "Operation Regulations for Overhead Transmission Lines", a safe distance should be maintained between the transmission line and the trees. If the above-mentioned safe distance is exceeded, the trees are likely to pose a safety hazard to the transmission line

[0004] In related technologies, manual on-site surveys are usually used, which consumes a lot of manpower and material resources, and the degree of automation and accuracy are low.
