Abstract

The invention relates to a text detection and recognition method and system and computer equipment. The method comprises the following steps: collecting sample images at different angles to constructa sample image set; training the classification model based on the sample image set to obtain an angle correction model; uniformly adjusting the sample images into standard angles, labeling real textboxes of the sample images, calculating anchor boxes of the sample image set by adopting a K-means clustering algorithm, and inputting the sample images, the real textboxes and the anchor boxes into ayoloV3 network for training to obtain a textbox detection model; training the CRNN based on the sample image marked with the textbox to obtain a text recognition model; and performing text detection and recognition on the to-be-detected text image according to the angle correction model, the textbox detection model and the text recognition model. According to the method, the low-end training difficulty of the yoloV3 network is reduced, so the text detection and recognition efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of text recognition, in particular to a text detection and recognition method, system and computer equipment. Background technique [0002] Text detection refers to the technology of accurately detecting the location of text from a picture. Text recognition, as the name implies, is a technology that recognizes text in a picture from a fixed position in the picture. At present, text detection and text recognition technologies are applied to various fields. For example, in licensed consumer financial institutions, a large number of certificate reviews and content reviews are carried out every day. The certificate pictures are mainly recognized by human eyes. Using text detection and recognition technology for document review can greatly improve work efficiency. In recent years, with the development of computer vision technology, text positioning and recognition in natural scenes has attracted great attention...
