AI Technical Summary

Problems solved by technology

However, the method of manual labeling using labeling tools is inefficient, time-consuming, and subject to large subjective errors. If the algorithm needs to be trained with a large number of comprehensive training sample sets, it will take a very long time, which is not conducive to rapid parameter tuning and verification of the algorithm.

Abstract

The embodiment of the invention provides a text position labeling method and device. The text position labeling method comprises the steps of determining a target area where a to-be-labeled object islocated and a first angular point coordinate corresponding to the target area in a to-be-processed image, wherein the to-be-labeled object comprises text information; obtaining a second angular pointcoordinate of a labeling reference area and text position information in the labeling reference area; determining a transformation matrix according to the first angular point coordinates and the second angular point coordinates; and determining text position information in the to-be-labeled object according to the transformation matrix and the text position information in the labeling reference area, and labeling the to-be-labeled object. According to the technical scheme, the text position labeling efficiency and the text position labeling accuracy can be greatly improved, and the text position labeling time is greatly shortened.

Description

technical field [0001] The present application relates to the technical field of artificial intelligence, in particular, to a method and device for marking text positions. Background technique [0002] When handling business (such as online loan business, etc.), users are often required to upload photos of relevant certificates (such as real estate certificates, etc.) through a user terminal (such as a mobile phone, etc.). After the background server receives the certificate photo uploaded by the user, it will extract the relevant certificate information (such as the owner of the house, the location of the house, the production certificate number, etc.) from the certificate photo, and then carry out corresponding processing according to the extracted certificate information business processing. [0003] In order to be able to extract the certificate information in the certificate photo, it is usually necessary to mark the specific position of the various certificate informa...
