Abstract

The invention discloses a character detection method and device, and the method comprises the steps of obtaining a to-be-detected image, and converting the to-be-detected image into a grayscale image;converting the grayscale image into a binary image through binarization; performing morphological transformation on the binary image; and obtaining a contour of a color area representing a characterpart in the binary image after morphological transformation, and determining an area corresponding to the contour in the to-be-detected image as a character detection area. By utilizing the method, the character detection speed can be increased, the character detection accuracy is improved, and the user experience is improved. The invention also discloses a corresponding apparatus and a computer readable storage medium.

Description

technical field [0001] The present application relates to the technical field of text detection, and in particular to a text detection method, device, equipment, and computer-readable storage medium. Background technique [0002] At present, there is a demand for text detection in many application fields, and it is desired that the text detection is fast and accurate, and the power consumption of the text detection equipment is low. Text detection technologies in the prior art mainly include: text detection based on traditional computer vision, and deep learning text detection based on artificial intelligence. However, in practical applications, text detection methods based on traditional computer vision are affected by factors such as light, noise, and background images, and the accuracy of text detection and recognition is very low; while deep learning text detection methods based on artificial intelligence are mostly Under normal circumstances, the accuracy of text detec...
