Abstract

The invention provides a character sorting method based on a binary tree, a character sorting device based on the binary tree, an optical character sequence positioning and recognition method, an optical character sequence positioning and recognition device, electronic equipment and a computer readable storage medium. The character sorting method based on the binary tree comprises the following steps: performing pattern collection in a region comprising a target character sequence to obtain a pattern set; traversing each pattern in the pattern set, and placing the patterns in the same row or column in the same binary tree; and sequentially identifying patterns at each node from the binary tree to obtain a target character sequence.

Description

technical field [0001] The present disclosure relates to the field of image recognition, and more particularly relates to a binary tree-based character sorting method, a binary tree-based character sorting device, an optical character sequence recognition method, an optical character sequence recognition device, electronic equipment, and a computer-readable storage medium. Background technique [0002] Optical character recognition is the process of analyzing image files with text data to obtain text and layout information. In the application scenario, recognizing text information in natural scene pictures is much more difficult than text recognition in scanned document images. This is because: characters have different sizes, fonts, colors, brightness, contrast, etc.; text lines can have horizontal, vertical, curved, rotated, twisted, etc.; text areas in images may have deformations (perspective, affine transformation) , incomplete, blurred, etc.; natural scene images have...
