A method of position and attitude measurement of vehicle using fan shaped laser beam and corner cube

摘要

A method is proposed to measure the position and attitude of a vehicle on the road by use of laser transceivers on the vehicle and retro-reflecting targets on a side of the course. The laser transceivers emit fan shaped laser beams and detect the returned laser beams reflected by the retro-reflecting targets. The time data when the laser beams return to the transmitter vary, depending on the movement of the vehicle. An onboard computer calculates the position and attitude from the time data. The measurement principle and the simulation results are reported.
