Position Method with One Point Laser Tracking for Navigation of Vehicles (1st Report)

Measurement of the Angle between Tracking Laser Beam and Reference Axis

Abstract

The position measurement methods for robotics vehicles navigation have been proposed by emitting various laser beams into various fixed retroreflectors. Authors thought up a position measurement method, emitting only one laser beam into a retroreflector, through introduction of a reference axis. The method is based on the measurement of an angle between the laser beam and the reference axis. To construct the reference axis through the standard point on the site, a double corner-cube is proposed here. It is shown that the angle between tracking beam and the reference axis can be measured continuously with utilizing the characteristic of the double corner-cube while tracking the standard point by laser beam.
