Power transmission and transformation line transfer and change environment water conservation supervision method based on high-resolution remote sensing

Abstract

The invention relates to a power transmission and transformation line transfer and change environment water conservation supervision method based on high-resolution remote sensing. According to the method, an image matched with a power transmission and transformation relocation line is obtained through preprocessing of atmospheric correction, geometric correction, image fusion, image registration and the like based on a remote sensing image T before construction and a remote sensing image T in construction, and then different typical ground features are classified based on a maximum likelihood method; the extracted result construction disturbance range is classified by using the construction disturbance range and the shape information of the construction road, and finally the extracted result is checked and corrected by using a man-machine interaction visual interpretation method and a pre-construction remote sensing image, and the attributes such as the construction disturbance area, the length and width of the construction road and the like are calculated.

Description

technical field [0001] The invention relates to a monitoring method for relocation, modification, environmental protection, water and water protection of power transmission and transformation lines based on high-resolution remote sensing. Background technique [0002] During the relocation of power projects, point-shaped excavated towers, spoil grounds, and a large number of construction access roads are formed along the transmission line, as well as engineering sites such as material yards and spoil yards left after completion, which inevitably affect the ecological environment around the line. make an impact. The existing monitoring methods for environmental, water and water protection of relocation and modification lines of power transmission and transformation projects mainly include: 1) traditional manual measurement, which needs to be checked from the starting position to the end position of power transmission and transformation, and the verification content includes b...

Problems solved by technology

[0004] 1. The power transmission and transformation line is long, the number of towers is large, the distribution is wide, the terrain along the line is complex, and manual on-site inspection is difficult. There are shortcomings such as long inspection period, low efficiency, inaccurate data, and omissions.

[0005] 2. The artificial interpretation method of remote sensing images in the environmental protection monitoring of power transmission and transformation lines has the disadvantages of heavy interpretation workload, low work efficiency, and high human subjectivity.
