Problems solved by technology

[0003] If the distance between the tree and the wire of the transmission line does not meet the safety requirements, periodic pruning and felling will be arranged. Therefore, the annual operation and maintenance of the transmission line involves a large number of tree pruning and felling engineering quantities. It is inefficient to measure the tree pruning and felling area by manual measurement

Embodiment 1

[0027] figure 1 It is a flow chart of an area identification method provided by Embodiment 1 of the present invention. This embodiment is applicable to the identification of a tree barrier felling area. The method can be executed by an area identification device, and specifically includes the following steps:

[0028] S110. Obtain RGB images and multi-spectral images of complete line channels to be identified before and after tree barrier felling.

[0029] RGB images and multi-spectral images before and after pruning are taken by drones equipped with cameras. Multispectral refers to the fact that sunlight is a continuous spectrum of different wavelengths, and its wavelength distribution ranges from short to long. Visible light of different colors exhibits color changes due to differences in wavelength. Due to the difference in the properties of different objects, when receiving sunlight, the ratio of the surface of the object to absorb and reflect sunlight is also different....

Embodiment 2

[0043] figure 2 It is a flow chart of an area recognition method provided by Embodiment 2 of the present invention. This embodiment is a further optimization based on the previous embodiment. The tree block area image before felling and the tree after felling After inputting the image of the tree barrier area into the trained area recognition model to obtain the image of the tree barrier felled area, the method further includes: calculating the area of ​​the tree barrier felled area according to the image of the tree barrier felled area. Provide powerful data support for engineering quantity settlement.

[0044] Such as figure 2 As shown, it specifically includes the following steps:

[0045] S210. Obtain RGB images and multi-spectral images of complete line channels to be identified before and after tree barrier felling.

[0046] S220. Obtain an image of the tree barrier area before felling according to the RGB image of the complete line channel to be identified before t...

Embodiment 3

[0053] image 3 A structural diagram of an area identification device provided in Embodiment 3 of the present invention, the area identification device includes: an image acquisition module 310, an image acquisition module 320 of a tree barrier area before felling, an image acquisition module 330 of a tree barrier area after felling, and a tree barrier area The deforestation area image acquisition module 340 .

[0054] Among them, the image acquisition module 310 is used to obtain the RGB image and the multi-spectral image of the complete line channel to be identified before and after tree barrier felling respectively; The RGB image of the line channel and the multi-spectral image of the complete line channel to be identified before the tree barrier is felled obtain the image of the tree barrier area before felling; the image acquisition module 330 of the tree barrier area after felling is used for according to the complete to-be-identified image after the tree barrier is fell...

Abstract

The embodiment of the invention discloses a region identification method and device, equipment and a medium. The method comprises the steps: respectively obtaining an RGB image and a multispectral image of a complete to-be-identified line channel before and after tree barrier felling; obtaining a tree barrier area image before felling according to the RGB image of the complete to-be-identified line channel before felling of a tree barrier and a multispectral image of the complete to-be-identified line channel before felling of the tree barrier; obtaining a cut tree barrier area image accordingto the RGB image of the complete to-be-identified line channel after the tree barrier is cut and the multispectral image of the complete to-be-identified line channel after the tree barrier is cut; and inputting the tree barrier area image before felling and the tree barrier area image after felling into a trained area recognition model to obtain a tree barrier felling area image. According to the technical scheme provided by the embodiment of the invention, the problem that the efficiency of manually measuring the tree barrier felling area is low is solved, automatic extraction of the tree barrier felling area is achieved, and the effect of improving the tree felling area obtaining efficiency is achieved.

Description

technical field [0001] Embodiments of the present invention relate to image processing technologies, and in particular to an area recognition method, device, equipment and medium. Background technique [0002] The measurement and pruning control of the safe distance between trees and conductors in the transmission line corridor is an important operation and maintenance work of transmission line operation and maintenance. During the daily growth process, the trees in the transmission line corridor will periodically grow close to the wires. If the safe distance is less than the operation and maintenance requirements, it will cause the wires to discharge to the trees, causing line failures and wildfires. [0003] If the distance between the tree and the wire of the transmission line does not meet the safety requirements, periodic pruning and felling will be arranged. Therefore, the annual operation and maintenance of the transmission line involves a large number of tree pruning...
