Problems solved by technology

If there are a lot of document pictures collected, manual labeling will consume a lot of time and the efficiency is very low
If it is necessary to use a large number of comprehensive training sample sets to train the algorithm, it takes a very long time, which is not conducive to the rapid parameter tuning and verification of the algorithm

Abstract

The embodiment of the invention discloses a text labeling method and device and a storage medium. According to the embodiment of the invention, the reference image can be obtained; marking a pluralityof angular point coordinates of a target area in the reference image and text position coordinates in the target area; obtaining a target image, respectively marking a plurality of angular points ofa target area in the target image; and calculating a perspective transformation matrix according to the plurality of angular point coordinates in the reference image and the plurality of angular pointcoordinates in the target image, and calculating text position coordinates in the target image according to the perspective transformation matrix and the text position coordinates in the reference image. According to the embodiment of the invention, after the reference image is preprocessed, the perspective transformation matrix between the reference image and the target image is calculated, so that the text position in the target image is calculated, the text position in the image can be quickly recognized and labeled, and the text labeling efficiency is greatly improved.

Description

technical field [0001] The invention relates to the field of data processing, in particular to a text labeling method, device and storage medium. Background technique [0002] At present, with the continuous development of the artificial intelligence process, text recognition has also become an indispensable part of the process. Text recognition relies on computer vision technology, which is mainly divided into two parts: text detection in images and text content recognition. Among them, the main function of text detection is to locate the position of the text in the image to facilitate the later recognition of the text. Therefore, text detection plays a vital role in the entire text recognition process. [0003] For example, when detecting the text in the certificate, it can be recognized through the certificate text detection algorithm model trained by a large number of samples. When training the document text detection algorithm model, it is necessary to label the text...
