Method research of robot multi-sensor information fusion based on D-S evidence theory

Based on the D-S evidence theory,the dempster synthesis law was improved using the ideas of weighted average and evidence similarity,and then the information detected by photoelectric encoder,CCD camera and the laser sensors was fused.The experiment results showed that the improved D-S evidence theory can eliminate the noise interference,handle signals smoothly.Therefore robot can implement obstacle avoidance safely by doing autonomous navigation,obstacle detecting and track planning.
