Laser scanner for navigating a vehicle

The invention relates to a laser scanner for navigation of a vehicle. For this purpose, the laser scanner has a light transmitter for emitting a transmitted light beam, a rotatable deflection unit for periodic deflection of the transmitted light beam into the field of view, a light receiver for generating a reception signal from the light beam reflected by landmarks in the field of view, a housing, an angle measurement unit for determining the angular position of the deflection unit relative to the housing, a rotation rate sensor for determining rotational movements of the scanner relative to its surroundings, and an evaluation unit which is designed to generate measured values based on the reception signal that indicate whether and in which direction at least one landmark is detected. From the measured values, the evaluation unit calculates position and navigation data, whereby a correction unit is provided which is designed to determine rotations of the scanner with respect to the rotation axis of the deflection unit and to compensate for the influence of the rotations on the measured values. In order to provide a laser scanner whose position determination is improved under the influence of arbitrary rotational movements and linear movements, it is proposed that the correction unit be designed to additionally determine orientation changes of the laser scanner with respect to at least one axis which is at an angle not equal to 0° to the rotation axis of the deflection unit, using the data from the rotation rate sensor, whereby the correction unit additionally has a linear motion sensor for detecting linear velocities and accelerations, in order finally to compensate for the influence of the additionally determined rotative and linear motion data on the measured values.
