Abstract [en]

A prototype of an optical navigation system for autonomous vehicles has been built. It consists of an He-Ne laser, a rotating mirror, an incremental encoder, a receiving optical system, a low-noise detection system and some controlling and computing microcomputers. The prototype is mounted on-board an experimental autonomous vehicle. The vehicle is of the tricycle type with the drive and steer functions implemented in the front wheel. The number of beacons visible from the vehicle is normally much greater than three, which is the minimum needed to evaluate the position and direction of the vehicle uniquely. This redundancy makes the system robust against false detections and blocked beacons and also improves the accuracy. Another benefit from the great number of beacons is that the pattern of angles measured to the beacons gives the position and direction of the vehicle without the beacons identities' being known before-hand. The experimental set-up and some measurement results are presented
