Two-stage braille detection and identification method based on target detection

A two-stage Braille detection and recognition method based on target detection is characterized in that Braille detection and recognition particularly refers to detection and recognition of each Braille character in a paper Braille scanned picture, and through a target detection technology in the field of computer vision, firstly, all Braille lines in the picture are detected by using a Braille line detection model; and performing further detection and identification on the basis of the braille lines by using a braille single character detection model to directly obtain positions and categories of all braille characters in the braille lines. According to the method, a good detection and recognition model can be obtained through training by using a small amount of data, follow-up work of braille machine translation is facilitated, and meanwhile the difficulty and cost of training data labeling can be reduced. 一种基于目标检测的二阶段盲文检测识别方法，其中盲文检测识别特指将纸质盲文扫描图片中的每个盲文字符检测并识别出来，通过计算机视觉领域的目标检测技术，首先使用盲文行检测模型检测出图片中的所有盲文行，然后使用盲
