Embodiment approach

[0033] For the aforementioned step S104, the embodiment of the present invention provides an implementation manner of determining multiple point cloud cutting intervals corresponding to the source point cloud file according to the coordinate values ​​of the target point cloud in the source point cloud file, refer to the following steps 1 to 2 :

[0034] Step 1: Divide the source point cloud file into a plurality of first point cloud sets according to the point cloud extraction ratio. Among them, the point cloud extraction ratio is positively correlated with the running memory of the terminal device, that is, the larger the running memory, the larger the point cloud extraction ratio. Exemplarily, the point cloud extraction ratio can be set to 50%. Considering that in practical applications, the source point cloud file is large in size, and the terminal device cannot identify all the tower point clouds in the source point cloud file at the same time. Therefore, in this embodimen...

Abstract

The present invention provides a point cloud cutting method, device and terminal equipment, comprising: acquiring a source point cloud file to be processed; determining the corresponding A plurality of point cloud cutting intervals; Collision detection is performed on each point cloud cutting interval and the source point cloud file to obtain a collision detection result; according to the collision detection result, the source point cloud file is cut into multiple A target point cloud subfile. The invention can remarkably improve the difficulty of point cloud processing and transmission.

Description

technical field [0001] The present invention relates to the technical field of point cloud processing, in particular to a point cloud cutting method, device and terminal equipment. Background technique [0002] With the development of laser technology and the increasingly urgent requirements for the digitization and intelligence of power grids, the point cloud density and data volume collected by the laser point cloud of transmission lines are increasing, and the point cloud file usually reaches tens of GB (Gigabyte, auspicious characters). section), or even hundreds of GB, which brings great difficulties to the processing and transmission process of point cloud files. SUMMARY OF THE INVENTION [0003] In view of this, the purpose of the present invention is to provide a point cloud cutting method, device and terminal device, which can significantly improve the difficulty of point cloud processing and transmission. [0004] In a first aspect, an embodiment of the present ...
