In order to solve the problems of large ranging error and low efficiency in the current laser range finder,a new type and high precision laser rangefinder is designed. First the laser rangefinder receiving system was designed.Then designed the laser signal tracking and denoising technologies to obtain ideal and precise output results. Finally,the laser rangefinder ws used in robot obstacle avoidance. The performance is analyzed,the results show that the ranging accuracy of the rangefinder is up to 95%,and the accuracy is better than the tradition,which can improve the accuracy of robot obstacle avoidance,and has wide application prospects.
