Abstract: With the development of intelligence, image processing technology has become more and more widely used in our lives and production, especially in intelligent robots. Aiming at the current research status of blind guide robots at home and abroad, a kind of blind guide robot based on machine vision is designed. This design can detect and recognize the types of surrounding objects and the distance to the robot through monocular distance measurement combined with You Only Look Once Version3 (YOLO V3) algorithm, and inform the blind by phonetic sound. Guide robot completes autonomous combined with various sensors navigation; the blind person walks under the guidance of robots, which greatly compensates for the blind^,s visual defects. From the results of the simulation experiment environment, it can be seen that the guide robot realizes the functions of advance, stop, turn and obstacle avoidance, which can also realize the function of indicating the type and distance of the obstacle in front, thereby providing a safe guarantee for the blind to travel.
