In this paper, the method to enhance the accuracy of braille block recognition through a camera to help visually impaired pedestrians is proposed. This paper proposes an accuracy improvement technique that extracts the regions of interest (ROI) by detecting braille blocks in real time through a combination of YOLO, binarization, and vertex extraction algorithms. Robust binarization is possible by setting flexible color boundaries for each frame so that the extracted ROI can be binarized accurately and efficiently. After detecting the vertices in the binarized image, the type of a braille block is confirmed based on number of vertices and information provided in the matching table. Based on the experimental results, this research showed better performance in generating braille block information than existing studies. If you use the proposed method of the braille block recognition technology described in this paper, it will not only help visually impaired pedestrians to walk stably, but will also contribute to the development of walking assistance devices for the visually impaired. |
