Problems solved by technology

[0005] Considering that there are thousands of power lines in a large city, the efficiency of point cloud integration of power lines manually is low and the labor cost is also high.
In addition, since the ownership of power lines is often changed according to actual needs, for example, two lines may be merged, resulting in frequent rework and reprocessing of data by data processors

Embodiment Construction

[0034] see figure 1 , which is a flowchart of a method for dynamically singulating power line point clouds according to an embodiment of the present invention.

[0035] The steps of the method for dynamic singulation of power line point cloud based on spatial database in this embodiment are as follows:

[0036] S1 obtains the wire point cloud coordinates of the power line;

[0037] S2 converts the point cloud coordinates of the wire into a vector line and stores it in a spatial database;

[0038] S3 inputs the coordinate information of the point to be queried in the spatial database, and locates the corresponding target vector line;

[0039] S4 converts the target vector line into a target vector surface;

[0040] Based on the coverage technology of the spatial database, S5 highlights the target vector area point cloud to be queried.

[0041] The present invention stores the vector lines converted from point cloud data through the spatial database, can accurately locate th...

Abstract

The invention discloses a power line point cloud dynamic monomerization method based on a spatial database. A spatial database is used for storing vector lines converted from point cloud data; when arequired point is queried, a corresponding vector line can be accurately positioned, then the vector line is converted into a vector plane according to an empirical value, local brightening of the power line wire point cloud is realized through rasterization processing, a point cloud area where the point to be queried is located is covered in a targeted manner, and automatic and dynamic power linepoint cloud monomerization is realized.

Description

technical field [0001] The invention relates to the technical field of point cloud data processing, in particular to a method for dynamically singulating power line point clouds based on a spatial database. Background technique [0002] Power line point cloud has the characteristics of high geometric accuracy and low cost of acquisition, and is widely used in power inspection, power facility management and other fields. [0003] According to the management method of power facilities in my country, power facilities are generally managed segmentedly with the power line as the unit, and the point cloud data collected by drone flight, for the sake of collection efficiency and cost, the point cloud of different power lines will be Centralized collection is carried out according to the flight range, that is, the collected point cloud data is not divided according to the line ownership, but according to the flight range, so that the user cannot know which power line a certain point ...
