【Abstract】 At present, there are more than 17 million blind people in China, and real-time detection of blind road scenes is an important prerequisite to ensure the safety of blind people. Aiming at the actual scene of the blind travel, this paper uses the YOLOv3 algorithm based on Edge Computing to realize the real-time recognition of blind road scenes. Firstly, the Edge Computing model is introduced to ensure the real-time performance of blind road data processing. Then, YOLOv3 algorithm is used to detect blind road obstacles, and data enhancement is performed to improve the detection performance of the algorithm for blind road obstacles. Finally, YOLOv3 is deployed on Edge Computing devices for training, and the real-time detection effect of the algorithm is improved by GPU parallel computing. The experimental results show that the detection efficiency of blind road scene recognition of the method is greatly improved compared with the traditional blind road recognition method, and the practical application can meet the navigation needs of the blind travel.更多还原
