Disconnection and connection checking method, device and equipment and readable storage medium

Abstract

The invention relates to a disconnection and connection checking method, device and equipment and a readable storage medium. The method comprises the steps of obtaining an image before disconnection and an image after connection; determining a first feature point set of the image before disconnection and a second feature point set of the image after connection based on a scale invariant feature conversion algorithm, and correspondingly converting the first feature point set and the second feature point set into a first array and a second array; calculating according to the first array and the second array to obtain an affine transformation matrix; detecting whether the photographing range of the image before disconnection is smaller than the photographing range of the image after connection; if yes, determining a to-be-cut range of the image after wiring based on the affine transformation matrix and the image before unwiring, and cutting the image after wiring; and recognizing characters in the image before wire dismounting and the cut wiring image to obtain a first character recognition result and a second character recognition result, and further judging whether an error exists in the wire dismounting and wiring process or not. According to the invention, the accuracy and efficiency of connection and disconnection checking can be improved, and the labor cost is reduced.

Description

technical field [0001] The present application relates to the technical field of industrial scenarios, and in particular to a method, device, equipment, and readable storage medium for disconnection checking. Background technique [0002] With the development of industry and the emergence of large-scale and complex man-machine systems, the negligence and errors caused by human factors cannot be ignored. The industrial field represented by the nuclear industry is particularly affected, and such omissions can easily cause safety hazards and serious losses. [0003] In the industry, for a large number of dense and complex cabinet wiring reconnection and comparison scenarios, the traditional method uses manual comparison to check the changed wiring. That is, the staff holds the wiring disconnection guidance document, carefully finds and operates the corresponding wiring according to the guidance document during the disconnection process, and checks whether the wiring is correct...
