Design of AGV Positioning Navigation Control System Based on Vision and RFID

Abstract

A design of composite navigation control system based on RFID and vision is proposed for problems, such as low positioning, poor stability, high cost, of the present AGV navigation ways. AGV recognizes the station with RFID firstly, then AGV builds an image recognition system with visual technology to achieve the accurate positioning. In this way, AGV can accomplish complex navigation tasks more accurately and efficiently. Low recognition precision of guides and noise interference can be solved with software by using gray image segmentation, image edge extraction, image denoising and linear fitting. The positioning accuracy of AGV is raised to 5 mm, meanwhile the angle precision is raised to 0.1° in application. The system not only satisfies the continuous positioning in large space, but also meets the requirement of high precision positioning, and realizes industrial automation.
