Problems solved by technology
[0003] The technical problem to be solved by the present invention is to provide a method for calculating the division of power transmission lines based on laser point clouds, so as to solve the problem of using laser point cloud data of transmission lines in the prior art. The cloud data and the projected laser point cloud data elevation difference are judged. This method cannot guarantee the accuracy of the laser point cloud data share and other technical problems.

Embodiment Construction
[0016] A laser point cloud-based calculation method for transmission line shares, including:
[0017] Step 1. Calculate the minimum coordinate value and maximum coordinate value of the line laser point cloud data;
[0018] By traversing the laser point cloud coordinate data (X, Y, Z) of the line, the minimum coordinate value of the line laser point cloud data (X 1 , Y 1 ,Z 1 ), the maximum coordinate value (X 2 , Y 2 ,Z 2 ), as the judgment of the integrity of the subsequent transmission line.
[0019] Step 2. Use the laser point cloud data with the minimum coordinate value as the seed point, and obtain the laser point cloud data within the coordinate increment of the seed point through the coordinate increment of 0.8 m to 1 m to form the laser point cloud data of the split line. The maximum value of the obtained laser point cloud data is used as a new seed point. In this way, the laser point cloud data of the transmission line can be avoided from being divided into oth...

The invention discloses a power transmission line stranding calculation method based on laser point cloud, which comprises the following steps: 1, calculating the minimum coordinate value and the maximum coordinate value of the laser point cloud data of the power transmission line; 2, using the laser point cloud data of the minimum coordinate value as a seed point to obtain the laser point cloud data within the range of the seed point coordinate increment, and taking the obtained laser point cloud data maximum value as a new seed point; 3, repeating the step 2 until the new seed point does nothave laser point cloud data in the range of coordinate increment, and obtaining the maximum coordinate value of the laser point cloud data of the split line; 4, comparing the maximum coordinate valueobtained in the step 3 with the maximum coordinate value obtained in the step 1, and if the difference does not exceed 0.5 m, the transmission line of the sub-strand is complete, otherwise, the sub-strand is a part of the transmission line; 5, until the power line point cloud data is completely divided; the invention solves the technical problems that the existing technology cannot guarantee theaccuracy of the laser point cloud data dividing and the like.
Description
technical field [0001] The invention belongs to the monitoring technology of power transmission lines, in particular to a method for calculating the division of power transmission lines based on laser point clouds. Background technique: [0002] The split calculation method of transmission lines based on laser point cloud is an important and key step in the analysis and display of laser point cloud data of transmission lines. The split laser point cloud data directly affects the analysis quality and display effect of laser point cloud data. At present, the split method of laser point cloud data is mostly based on the height information of the power line, and the elevation difference between the laser point cloud data of the transmission line and the projected laser point cloud data is used to judge. The influence of the terrain of the power line corridor or the sag of the power line will cause the power line to be wrong. points, this method cannot guarantee the accuracy of l...
