Blind person auxiliary walking method and system based on deep learning target detection

Abstract

The invention discloses a blind person auxiliary walking method and system based on deep learning target detection. A DarkNet-19 target detection model optimized based on a YoLov2 model is constructed, a training set is utilized to train a DarkNet-19 target detection network, a development set is utilized to test the trained model, and the model is continuously optimized according to test result optimization; a model weight file is obtained according to the trained and optimized DarkNet-19 target detection network, the model weight file is read into an ImageAI library fused with a non-maximum suppression algorithm to obtain an auxiliary blind person walking detection model, and the auxiliary blind person walking detection model is verified by using a test set until a convergence condition is reached; a to-be-detected monitoring video is obtained, a blind person walking assisting detection model is adopted to detect the road surface condition in each real-time monitoring picture in the monitoring video, various obstacles encountered on the road by the blind person, the traffic condition and the road surface information are fed back to the blind person, and the technical problems that an existing blind person walking assisting tool is low in intelligent degree, and cannot be safely and accurately assist the blind in walking are solved.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to a method and system for assisting blind people to walk based on deep learning object detection. Background technique [0002] Blind people, as a vulnerable group, have many inconveniences in their daily lives and have received attention from all walks of life. Blind people usually rely on blind poles or guide dogs when traveling, but in many road conditions, blind poles and guide dogs cannot distinguish, such as looking for zebra crossings, judging whether traffic lights are passable, etc. At the same time, there are still many places such as supermarkets, bus stations, etc., that do not have paved walkways for the blind, which makes it difficult for the blind to walk in many cases, and safety accidents occur. Without the help of others, it is difficult for the blind to reach their destination safely. Therefore, it is a technical problem to be solved urgently by...
