Paper Abstract

This paper presents a laser vision wheel alignment system that includes the design of the system, the working principle, the deduction of mathematical model. Coordinates unification of multiple line-structured laser sensors, which is so called global calibration, is to obtain the position and direction parameters of the multi-sensor's light plane coordinates in the world coordinates system. This paper elaborates on the method of the coordinates unification method of multi-sensors by establish a world coordinates system using two theodolites, which shows the advantage of facile movement, high accurate and most suitable to establish flexible coordinates system. The calibration accuracy is δ equals ± 0.1 mm.
