Abstract

The invention discloses a nameplate recognition method based on depth learning. The method comprises the following steps: identifying and determining an area where the nameplate is located by using anobject detection algorithm to identify an object picture; then edge detection is carried out by using Hough transform, and the slanted image is automatically corrected by affine transform; cutting the picture of the nameplate into text to determine the position information of each line of text; the segmented text is recognized and the recognition result is obtained. The invention also includes anameplate recognition system based on depth learning. The invention adopts the depth learning algorithm to segment the nameplate at the line level, solves the problems of low Chinese character segmentation efficiency and low segmentation precision, and improves the recognition efficiency. CRNN algorithm is used to recognize line-level text, which improves the accuracy of text recognition.

Description

technical field [0001] The invention relates to the technical field of nameplate recognition, in particular to a nameplate recognition method and system based on deep learning. Background technique [0002] The traditional nameplate recognition usually uses the traditional Hough transform to detect the straight line in the picture, and uses the preset edge extraction algorithm to perform edge extraction processing on the scene image to be tested, obtain the corresponding contour image to be tested, and locate the edge in the contour image to be tested Nameplate outline area, this method must set different edge extraction algorithms according to different nameplates, and this kind of edge detection algorithm is relatively poor for nameplate extraction in complex environments. There are many devices in the substation, and there are many interference factors. The recognition accuracy of the nameplate based on the traditional algorithm is low. [0003] In the prior art, projec...
