Abstract

The invention discloses a power transmission line intelligent video distance measurement method. The specific distance and the angle between two cameras arrange at the front end at an interval are determined, wherein an intersection of an object whose distance needs to be measured exists in images of the two cameras; video images are collected by means of the cameras at the front end; one camera decompresses the collected video images and decomposes the video images into YUV pictures; the picture in one frame and the picture in the preceding frame are compared, background environment is updated in real time by means of self-learning, and a target object is eliminated from the background environment; pixel points of the eliminated target object in the cameras are calculated, and the distance of the target object is determined according to the position of the intersection of the object whose distance needs to be measured in the two images and the angles of the cameras. By means of the method, the distance of the target object close to power facilities can be measured conveniently in time, and safe operation of the power facilities is guaranteed.

Description

technical field

[0001] The invention relates to an intelligent video ranging method for power transmission lines. Background technique

[0002] As far as power facilities are concerned, how to analyze the distance near the facilities to know in time whether there is a safe distance between the target object and the power facilities has been a long-term goal pursued by technicians, and there is still no ideal method so far. Contents of the invention

[0003] The purpose of the present invention is to provide an intelligent video ranging method for transmission lines that can conveniently and timely measure the distance of target objects close to electric facilities.

[0004] Technical solution of the present invention is:

[0005] A transmission line intelligent video ranging method is characterized in that: specific steps

[0006] (1) Determine the specific distance and angle between the two cameras at the front end, and the objects to be measured must have intersections...
