Identification method and identification device for state of switch on-off indication board, and storage medium

Abstract

The invention discloses an identification method and identification device for a state of a switch on-off indication board, and storage medium, and belongs to the field of image processing and machine vision. The method comprises the following steps: S1, establishing and training a deep learning model for optical character recognition; s2, using the model trained in the step S1 to identify an image of an opening and closing indication board of an actual scene; s3, for the image of the opening and closing indication board of which the target cannot be successfully identified, performing preprocessing operation on the image, and then performing identification by using the deep learning model again; and S4, obtaining results output in the steps S2 and S3, and determining the results as final recognition results. According to the invention, the states of the switch opening and closing indication board under various forms and shooting conditions can be identified, the specific position of the opening and closing indication board does not need to be specifically positioned in advance, and the universality and robustness of identification are greatly improved.

Description

technical field [0001] The invention belongs to the fields of image processing and machine vision, and in particular relates to a recognition method, a recognition device and a storage medium for the state of a switch opening and closing indicator plate. Background technique [0002] At present, in electric power and other systems, the safe operation of equipment is one of the most important safety guarantees, and various relay switches are an important guarantee to ensure the safe operation of the system. The relay is an electrical control device, which is an electrical appliance that causes the controlled quantity to undergo a predetermined step change in the electrical output circuit when the change of the input quantity meets the specified requirements. Usually used in automatic control circuits, it is an "automatic switch" that uses small currents to control large current operations, so it plays the role of automatic adjustment, safety protection, and conversion circuit...

Problems solved by technology

This method requires the image to have high imaging quality, and requires manual complex feature design and extraction processes. At the same time, it also needs to locate and extract the specific position of the separation and closing signs before classification and recognition. The sorting process is relatively complicated, and the scope of application of the algorithm and robustness (the ability of the system to survive abnormal and dangerous situations) have certain limitations
