Intelligent identification method for transformer electrical nameplate steel seal fonts

Abstract

The invention discloses an intelligent identification method for transformer electrical nameplate steel seal fonts. The method comprises the following steps: S1, obtaining a nameplate image; s2, positioning a steel seal text area and a rectangular area, and cutting out a steel seal text area image with a clear contour; s3, performing graying processing on the steel seal image; s4, carrying out improved method image enhancement on the grayed image of the steel seal text to obtain an image with richer text details; s5, preprocessing the steel seal text enhanced image obtained in the step S4, removing noisy points, and highlightening characters; s6, performing text detection on the steel seal text image preprocessed in the S5 to obtain a steel seal character normalized image; and S7, performing text recognition on the steel seal character normalized image obtained in S6 to obtain nameplate information. According to the embodiment of the invention, recognition is stable, details are mergedafter image enhancement, detail loss in an image enhancement process is avoided, and the recognition accuracy is ensured.

Description

technical field [0001] The invention relates to the field of electric power technology, in particular to an intelligent identification method for steel stamp fonts on electrical nameplates of transformers. Background technique [0002] In recent years, the vigorous development of artificial intelligence technology has promoted the rapid development of target detection, intelligent recognition and other technologies. Among them, the intelligent recognition of characters is an important aspect. The method of intelligent identification of fonts on transformer electrical nameplate steel stamps is to use computers to obtain data information from pictures, use computers to replace human brains, use programs to process and analyze images, and then extract the required information from pictures to improve the stamped text on electrical nameplates of substation main transformers. The extraction of image information and the accuracy of recognition can realize the automatic and unifie...
