Abstract
The invention relates to a scanning optoelectronic detection device (7), in particular laser scanner, for a motor vehicle, comprising an optical emitter for emitting electromagnetic beams, comprising an optical receiver (10) for receiving beams (9) reflected at a target object in surroundings of the motor vehicle and for providing an electrical reception signal (19) depending on the received beams (9), and comprising an evaluation device (25) for detecting the target object depending on the electrical reception signal (19), wherein the emitter is designed to emit a respective emission beam for a multiplicity of different scanning angles within an entire scanning angle range, and wherein the evaluation device (25) is designed, for each scanning angle, to compare the reception signal (19) with a detection threshold and to detect the target object depending on the comparison, wherein the detection threshold is an angle-dependent threshold value function which has mutually different threshold values for the reception signal (19) for at least two different scanning angles of the emitter.
