Abstract

The invention provides a nameplate recognition model training method, a nameplate recognition method and a related device. The method comprises the following steps: acquiring sample image data acquired from a nameplate mounted on power equipment and equipment parameters recorded in the nameplate; writing the equipment parameters in the square frame into the imprint in the sample area data as label area data; label points are sampled for equipment parameters in the label area data; inputting the sample image data into an encoder to extract feature data; inputting the feature data into a regression network, and sampling reference points for impressions in the sample region data; inputting the feature data into a decoder, and reconstructing a print in the sample region data into a font as reference region data; and training an encoder, a regression network and a decoder according to the difference between the reference point and the label point and the difference between the reference area data and the label area data until the reference point is aligned with the reference area data. And the accuracy of identifying the equipment parameters recorded in the nameplate is improved.

Description

technical field [0001] The invention relates to the technical field of electric power, in particular to a nameplate recognition model training, a nameplate recognition method and related devices. Background technique [0002] In the power industry, there are many types and quantities of power equipment, such as electro-hydraulic drum brakes, power cables, power transformers, integrated distribution boxes, electric energy metering boxes, etc. The equipment parameters of these power equipment are usually recorded on the nameplate, The nameplate is attached to the electrical equipment. [0003] When promoting the process of digital management, technicians will collect image data on the nameplate, and use OCR (Optical Character Recognition, Optical Character Recognition) to identify the content of the nameplate on the image data. [0004] However, since the power equipment is mostly deployed outdoors, the aging of the nameplate is relatively obvious, and some of the contents ar...
