【Abstract】 To the vision guided intelligent vehicle,some ultrasonic sensors are added for obstacle avoidance. Intelligent vehicle can move along the lane marker through the information acquired by the CCD camera. The information of multiple ultrasonic sensors was researched by using the D-S evidential theory and the method of fuzzy logic. Information fusion and the model of ultrasonic sensor are included. The results of simulation give the tracks of the intelligent vehicle when moving and avoiding obstacles in different environments. It indicates that this method of information processing can identify obstacles efficiently and makes satisfying results of navigation and obstacle avoidance.更多还原
