Abstract:

Aiming at the insufficiency of information acquired by a single sensor, a method of fusing the information acquired by camera and ultrasonic sensors was proposed for navigation. A method for segmenting the navigation path and identifying obstacle through the information of vision was put forward. D-S evidential theory and the method of fuzzy logic were used to fuse the information of the environment obtained by image processing and multiple ultrasonic sensors. Methods of information fusion, modeling of the ultrasonic sensors, image segmentation and mathematical morphology were included herein. The simulation and experiments indicate that the navigation path can be segmented efficiently and this method of information processing can identify obstacles efficiently and makes satisfactory results of navigation and obstacle avoidance.
