Problems solved by technology

In some more complex scenes, the text layout will be messy and cannot form a regular "line". In the above method, in more complex scenes, such as scenes with skewed characters and messy backgrounds, text regions are identified based on semantic segmentation results. Some characters may not be completely recognized when the characters are in the text, resulting in text recognition errors and poor robustness

Abstract

The invention provides a text recognition method, a device and equipment, and the method comprises the steps: extracting a text region image from a target image, and the text region image comprises atleast one character; extracting single-character images from the text area image, wherein each single-character image comprises a character; and identifying characters in each single-character imageto obtain a character identification result. The integrity of the recognized characters is ensured, the text recognition error rate is reduced, and the robustness is improved.

Description

technical field [0001] The present invention relates to the technical field of computer vision, in particular to a text recognition method, device and equipment. Background technique [0002] Text may appear in various scenes, such as shopping mall signs, item brands, various books, videos, etc. Text can help us better understand the relevant conditions of the scene, and then help make corresponding decisions, so in more scenes Both need to collect text images and recognize the text in the images. [0003] In a related text recognition method, after a text image is collected, a text region is extracted from the text image, the text region is semantically segmented, and characters in the text region are recognized based on the semantic segmentation result. In some more complex scenes, the text layout will be messy and cannot form a regular "line". In the above method, in more complex scenes, such as scenes with skewed characters and messy backgrounds, text regions are identi...
