Embodiment Construction

[0031] Exemplary embodiments of the present disclosure are described below in conjunction with the accompanying drawings, which include various details of the embodiments of the present disclosure to facilitate understanding, and they should be regarded as exemplary only. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the disclosure. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.

[0032] The text detection method of the embodiment of the present disclosure will be introduced below.

[0033] Generally speaking, text positioning is usually divided into segmentation-based schemes and detection-based free anchor text (anchor-free) schemes, respectively as follows:

[0034] Based on segmentation: directly predict the response of each pixel in the pic...

Abstract

The invention provides a text detection method and device, electronic equipment and a storage medium, and relates to the field of image processing and mode recognition, in particular to the text detection method and device, the electronic equipment and the storage medium. According to the specific implementation scheme, a target image is obtained, and the target image comprises a to-be-detected target text; a bounding rectangle of the target text and a plurality of first corner points of a target quadrangle are determined, the bounding rectangle is a minimum regular rectangle circumscribed to the target text, and the target quadrangle is determined by a plurality of target points on the target text and comprises the target text; and detecting target position information of the plurality of first angular points based on the bounding rectangle.

Description

technical field [0001] The present disclosure relates to the technical fields of image processing and pattern recognition, and in particular to a text detection method, device, electronic equipment and storage medium. Background technique [0002] In related technologies, when performing text detection, Anchor-based methods are aimed at the text prediction results of regular rectangles, but cannot cope with different degrees of rotation and irregular text shapes. Contents of the invention [0003] The present disclosure provides a method, device, equipment and storage medium for text detection. [0004] According to an aspect of the present disclosure, a text detection method is provided, including: acquiring a target image, wherein the target image includes target text to be detected; determining a circumscribed rectangle of the target text and a plurality of first corner points of the target quadrilateral, Wherein, the circumscribing rectangle is the smallest regular re...
