Abstract
The disclosed subject matter relates to a laser scanner for scanning a ground from a seaborne or airborne vehicle, comprising a scanning unit for emitting a fan-shaped scan pattern made of laser beams fanned out about a scan axis and for receiving the laser beams reflected off the ground and an evaluation unit connected to the scanning unit for evaluating the laser beams that are received. The laser scanner is characterized by a measuring unit that is designed to measure the height of the vehicle above ground, and an actuation device that can be anchored to the vehicle and that is connected to the measuring unit. The actuation device is designed to rotate the fan-shaped scan pattern of the scanning unit with respect to the vehicle about a first actuation axis that is different from the scan axis, depending on the measured height above the ground.
