Obstacle detection is a hot topic in the field of artificial intelligence. In view of obstacle detection and distance measurement in indoor complex environment

an indoor obstacle detection method based on optical flow method and ultrasonic ranging is proposed. The system is based on Raspberry Pi which is used optical flow obstacle detection algorithm and ultrasonic sensor to detect the image information and distance of the moving obstacle respectively at the same time. Experimental results show that the system can be well implemented in the intelligent car based on raspberry pi. It can achieve real-time detection of moving obstacle image information and location information.
