Image wireframe recognition method and server

Abstract

The invention provides an image wireframe recognition method and a server, which are applied to the technical field of image recognition. The method comprises the steps of after obtaining an original image comprising a to-be-recognized wireframe, correcting the original image to obtain a target image, and the to-be-recognized wireframe in the obtained target image being in a preset standard size; then obtaining a sub-image comprising the to-be-recognized wireframe from the target image based on the preset standard size, the size of the obtained sub-image being smaller than the size of the target image, further recognizing all candidate lines in the sub-image, determining wireframe side lines in all the candidate lines, and finally determining the to-be-recognized wireframe based on the wireframe side lines. According to the method, the size of the sub-image finally used for wireframe recognition is smaller than that of the target image, due to the fact that the recognition range is reduced, the influence of a part of interference lines in the original image can be eliminated, the recognition accuracy can be improved, meanwhile, due to the fact that the recognition range is reduced, the image content needing to be processed can be reduced, and the recognition efficiency can be improved.

Description

technical field [0001] The invention relates to the technical field of image recognition, in particular to an image wireframe recognition method and server. Background technique [0002] At present, image recognition technology has been widely used in many aspects such as electrical equipment deployment and information acquisition. For example, in the process of deploying electrical equipment such as inverters in photovoltaic power plants, equipment location tables for recording equipment deployment locations are often used. The equipment location table is prefabricated according to the electrical equipment arranged in rows and columns in the photovoltaic power station. During the installation of electrical equipment, the workers tear off the two-dimensional code label on each electrical equipment, and paste the label on the corresponding table in the paper equipment location table according to the row number of the equipment, that is, through the equipment record The table...

AI Technical Summary

Problems solved by technology

[0005] The inventor found that the image wireframe recognition method in the prior art needs to recognize all the lines in the original image, which not only has a large recognition range and low recognition efficiency, but also easily recognizes the interfering lines in the original image as wireframe edges, and recognizes Accuracy is not high
