Airborne LiDAR three-dimensional data acquisition method for establishing three-dimensional digital power transmission and transformation grid

Abstract

The invention discloses an airborne LiDAR three-dimensional data acquisition method for establishing a three-dimensional digital power transmission and transformation grid. The airborne LiDAR three-dimensional data acquisition method for establishing the three-dimensional digital power transmission and transformation grid comprises the following steps: collecting data, performing on-site survey, making an airborne LiDAR scheme, acquiring point cloud data, judging whether the point cloud data is qualified, denoising the point cloud data, splicing the point cloud data, judging whether the point cloud data is intact, correcting a point cloud data acquisition scheme, acquiring an image, judging whether image data is qualified, and storing the data. The airborne LiDAR three-dimensional data acquisition method for establishing the three-dimensional digital power transmission and transformation grid has the advantages of high measurement speed, easiness in implementation, high density and high accuracy of the acquired data, and the like; a mobile LiDAR measurement system is used for field acquisition, so that the working efficiency can be greatly improved.

Description

technical field [0001] The invention belongs to the technical field of electric power measurement, and in particular relates to an airborne LiDAR three-dimensional data acquisition method for constructing a three-dimensional digital grid for power transmission and transformation. Background technique [0002] The 500KV transmission grid is the main backbone grid of my country's power grid. It has many types of equipment, complex equipment structure and electrical connection relationship, and complex and changeable line corridor terrain. As an important power facility in the grid, substations have voltage levels Features such as high speed, dense equipment, and high security level have also brought difficulties to the visualized and intelligent management of the power grid. In order to effectively manage the power transmission and transformation grid and greatly improve the management level of the power grid, it is imperative to establish a three-dimensional digital grid for p...

Problems solved by technology

In addition, due to the imperfect preservation of the drawings of some construction units, there are even no drawings available for some equipment

The point cloud data collected based on fixed-point laser technology has basically met the requirements of equipment modeling, but because of the complex operation process and low efficiency of 3D data collection, which leads to increased project costs, it is less used
