Embodiment Construction

[0040] The present invention will be further described in detail below with reference to the accompanying drawings.

[0041] This embodiment is only an explanation of the present invention, and it is not a limitation of the present invention. Those skilled in the art can make modifications to this embodiment without creative contribution as needed after reading this specification, but only in the claims of the present invention are protected by patent law.

[0042] like figure 1 As shown, the present embodiment provides a method for identifying illegal buildings, which is characterized in that it includes the following steps:

[0043] S1: Acquire images containing power transmission lines in the aerial image set.

[0044] S2: Perform color quantization on the images in the aerial image set. Color quantization is quantized according to R*G*B colors, R∈[32,256], G∈[32,256], B∈[32,256].

[0045] S3: Calculate the salient value SAM(In) of each pixel In in the quantized image to...

Abstract

The invention relates to the technical field of identifying illegal buildings around power transmission lines, and provides a method for identifying illegal buildings. The salient value SAM(In) of the pixel In is calculated to obtain a SAM image; S4: Threshold cutting and morphological processing are performed on the SAM image to obtain the potential area of ​​illegal buildings in the image; S5: The second-order moment feature is calculated and identified Road section area, and eliminate the road section area in the potential area of ​​illegal buildings. S6: Identify the legal area on the aerial image set through the deep learning algorithm, and the legal area includes the tower base area and the area where the large vehicle is located; For the legal area identified in step S6, the identification result of the illegal building is obtained; the cost is low, the workload requirement is low, and the identification rate is high.

Description

technical field [0001] The invention relates to the technical field of identifying illegal buildings around power transmission lines, in particular to a method for identifying illegal buildings. Background technique [0002] Due to the wide distribution of tower bases, scattered locations and remote locations of 500,000-volt power transmission lines, they are often located in mountainous areas that are difficult to reach on foot. Therefore, because of its strong mobility and good environmental adaptability, drones are very suitable for the inspection of illegal buildings on power tower bases. Such illegal buildings include: houses, vegetable sheds, factories, etc. Through the path planning of the GPS coordinates of the UAV tower base, the UAV can take aerial photos along the power transmission and transformation lines, and after the aerial photography is completed, the illegal buildings near the power transmission and transformation lines can be identified. [0003] There a...
