Problems solved by technology

When existing recognition algorithms detect and recognize curved text, the detection network mostly focuses on detecting a single task and only locates the position of the curved text, but because the curved text contains too many background noise points, the subsequent recognition network cannot extract the text , resulting in poor recognition effect

Abstract

The embodiment of the invention provides a text recognition method and device, electronic equipment and a readable storage medium. The method relates to the field of artificial intelligence technology and cloud. The method comprises the steps of obtaining a to-be-recognized text image, wherein the to-be-recognized text image comprises a curved text area; extracting a text feature map of the to-be-recognized text image; determining a to-be-recognized text area in the to-be-recognized text image and area boundary information of the to-be-recognized text area based on the text feature map, wherein the to-be-recognized text area comprises a curved text area; correcting the to-be-recognized text region according to the region boundary information to obtain a corrected rectangular text region; and performing character recognition on the rectangular text area to obtain a text recognition result of the to-be-recognized text image. In the embodiment of the invention, the curved text region can be corrected into the rectangular text region, the background noise in the text region is reduced, and the recognition effect is improved.

Description

technical field [0001] The present application relates to the technical fields of image processing, artificial intelligence and big data. Specifically, the present application relates to a text recognition method, device, electronic equipment and readable storage medium. Background technique [0002] OCR (Optical Character Recognition, Optical Character Recognition) is an important research hotspot in the field of computer vision, and curved text recognition is an important application in OCR. In recent years, with the development of deep learning technology, OCR detection and recognition based on deep learning has become a mainstream trend. [0003] Among them, the OCR technology includes two networks, a detection network and a recognition network. The detection network is used to locate the position of the text, and the recognition network is used to identify the specific content of the text. When existing recognition algorithms detect and recognize curved text, the detec...
