Embodiment 1

[0037] see figure 1 , the embodiment of the present invention is based on the image processing method for measuring the safety distance of transmission lines, the method comprising:

[0038] S1. Acquire an image containing a target object, where the target object includes two target objects whose distance is to be measured;

[0039] Specifically, an image acquisition device, such as a camera, is set up at the power transmission line equipment site to acquire images of target objects. The target object can be two transmission lines, or overhead ground wire and overhead wire, overhead wire and tree, pull wire and drainage wire, overhead wire and house, overhead wire and ground, drainage wire and tower body.

[0040] It should be noted that when taking an image containing a target object, the image should only contain the target object and the target background as much as possible, and make the difference between the target object and the target background obvious, so as to faci...

Abstract

The invention discloses an image processing-based power transmission line safety interval measurement method, system and device, and the method comprises the steps: obtaining an image comprising a target object, and enabling the target object to comprise two target objects with to-be-measured intervals; carrying out segmentation processing on the image to obtain the target object; calculating pixel coordinates of the target object in the image; according to a transformation matrix of the pixel coordinates and the world coordinates, obtaining the position of the target object in the world coordinates through calculation, wherein the transformation matrix is the corresponding relation between a known world coordinate system and an image coordinate system; and calculating the distance betweenthe two power transmission lines according to the world coordinate position of the target object. According to the invention, the calculation of the power transmission line distance of the power gridcan be realized through image processing, and then the safety distance of the power transmission line can be judged.

Description

technical field [0001] The invention relates to a method, system and device for measuring the safety distance of transmission lines based on image processing, and belongs to the technical field of image processing. Background technique [0002] With the continuous improvement of high-voltage line grids, the voltage level of high-voltage lines is getting higher and higher, and the number of line kilometers is also increasing rapidly. The workload of line operation and maintenance is increasing, and the difficulty of inspection is also increasing. High-voltage lines are mainly transmission lines, which have been operating in the field for many years, and there are high-voltage lines crossing other voltage levels, as well as buildings and trees. When the weather or icing causes the sag to increase, the line will fail. Or a major accident, and the distance between the wire and the ground, the distance between the jumper and the tower, etc. can cause high-voltage line accidents. ...
