Abstract

The embodiment of the invention provides a text detection method and device based on image processing, a medium and electronic equipment, and the method comprises the steps: obtaining a text inclination angle of a to-be-detected image through Hough transform, and rotating the to-be-detected image through the text inclination angle, so as to obtain an inclination correction image; inputting the inclination correction image into a pre-trained text region detection model to obtain a text to-be-selected region in the inclination correction image; determining one or more text to-be-selected imagescorresponding to the to-be-detected image based on the text to-be-selected area, and performing graying processing on each text to-be-selected image; determining a binarization segmentation thresholdvalue according to the gray value of each pixel point in the text to-be-selected image subjected to the gray processing, and performing binarization processing on the text to-be-selected image by utilizing the binarization segmentation threshold value; and identifying the text information in the text candidate image after binarization processing. The method can improve the character recognition efficiency and recognition precision.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a text detection method based on image processing, a text detection device based on image processing, a computer-readable medium and electronic equipment. Background technique [0002] With the development of computer vision and deep neural network, the technology of text recognition has been greatly developed. This technology can not only be used for identification of documents such as ID cards, but also has broad application prospects in bill identification. However, in practical applications at present, there will be a certain degree of image distortion in the process of image collection, processing, transmission, etc., so the current application range of bill recognition is still small, the accuracy rate is still low, and the artificial effect cannot be fully achieved. . Therefore, it is of great significance to apply some means of image processing, establish effe...
