Problems solved by technology

[0003] Due to the immature technology, the mechanical error [-1Rad, 1Rad] of the gimbal during the rotation process results in no images being captured; the instrument recognition algorithm has a low tolerance for position errors in image capture, resulting in a decline in the instrument recognition rate

Embodiment

[0026] A method for identifying the value of an electric meter at an inspection point based on an intelligent robot in this embodiment, the execution steps are as follows:

[0027] 1) Shoot the standard image ImgStd of the inspection point; the robot moves to the designated position in the room autonomously, and sets the camera magnification Z, focus value F, horizontal angle H of the pan-tilt, and angle of the pan-tilt corresponding to the corresponding inspection point. Vertical angle V, and record the indoor position coordinates (PosX, PosY) of the current inspection point.

[0028] 2) Select the standard area ImgStdArea from the standard image ImgStd; the size of the standard area ImgStdArea is between [400*300, 800*700] pixels, and the meter area of ​​the inspection point is included in the standard area ImgStdArea.

[0029] 3) Establish the meter scale set (K, SV) of the inspection point, where Kϵ(1...n), SVϵ[0,2*π), K is the slope of the straight line where the pointer ...

Abstract

The invention relates to an intelligent robot-based recognition method for electric meter values ​​at inspection points, and belongs to the technical field of image recognition. The method performs the following steps: 1) Capture a standard image; 2) Select a standard area; 3) Establish a meter scale set; 4) Generate a training data set; 5) Perform training; 6) Obtain an image to be recognized; 7) Select an image to be recognized Small block; 8) Determine the most similar image block; 9) Determine the mapping relationship; 10) Determine the meter area in the image to be recognized; 11) Obtain the binarized image; 12) Fit the binarized image to determine the meter scale pointer; 13) Determine the meter value. The method has strong positioning error tolerance and high instrument recognition accuracy. The instrument recognition degree is about 60%. After adopting the method of the invention, the accuracy is increased to about 99%.

Description

technical field [0001] The invention relates to an intelligent robot-based recognition method for electric meter values ​​at inspection points, belonging to the technical field of image recognition. Background technique [0002] With the development of science and technology and the deepening of intelligence, mechanized and intelligent equipment gradually replaces manual labor and is used in mechanized tedious work. Just like the inspection work of power equipment, the use of intelligent inspection robots for inspection work solves the potential safety hazards caused by the special environment of the power supply room and the possible mistakes and / or errors caused by manual inspections. [0003] Due to the immature technology, the mechanical error [-1Rad, 1Rad] in the rotation process of the gimbal leads to the failure to capture images; the instrument recognition algorithm has a low tolerance for position errors in image capture, resulting in a decline in the instrument rec...
