Problems solved by technology

In the process of hierarchical clustering, it is necessary to pass a suitable threshold to stop the hierarchical clustering. If the threshold is not selected properly, it will lead to inaccurate positioning of the identified text lines in the entire scene.

Abstract

The present application provides a text line recognition method, device, and computing device. The method includes: based on the area characteristic information of the text area, determining the respective text blocks of the identified text areas to obtain at least one first text block; All the text regions in a first text block are fitted with a straight line at the coordinates of the central positions in the picture to obtain the first fitted straight line corresponding to each first text block; based on each central position in each first text block The distance from the coordinates to the first fitting straight line is to determine the first average distance from the coordinates of all the center positions in each first text block to the first fitting straight line; when it is determined based on the first average distance that there is When the first text block to be divided is required, the first text block to be divided is determined as the second text block, and is divided into at least two text blocks. The present application can accurately identify text lines of scene characters, and improve the robustness of text line identification.

Description

technical field [0001] The present application relates to the technical field of image recognition, and in particular to a text line recognition method and device, and computing equipment. Background technique [0002] Single text line analysis is performed on the scene text, which belongs to the layout analysis method. In the prior art, the bottom-up layout analysis method based on hierarchical clustering uses the attribute feature information of single-text regions or connected regions to calculate the similarity between single-text regions, and for two or more texts that meet the similarity threshold The single text area is merged layer by layer, and finally the text line where the text area is located is identified. In the process of hierarchical clustering, it is necessary to pass a suitable threshold to stop the hierarchical clustering. If the threshold is not selected properly, it will lead to inaccurate positioning of the identified text lines in the entire scene. ...
