The new navigation system for automatic guided vehicle

This paper designs a new navigation system for automatic guided vehicle (AGV). The system uses the CCD camera in front of the AGV to recognize and track the sign line on the ground, and to extract the position and the direction of the sign line. At the same time, the wheel encoders are used to get the running distance of the AGV finally, the DR algorithm can use the direction and the distance to calculate the accurate position of the AGV at real time. In the track for sign line, the system utilizes the feed-back algorithm to optimize the performance of image processing and remove the shaking of AGV In the summary, the novel navigation system can avoid the position error accumulated with time as general DR and cost lower; a plenty of examinations prove that the algorithm can efficiently improve the position precision.
