Patent ID: 10605919

Abstract:
A method for processing echo pulses of an active 3D sensor to provide distance measurements of surroundings in front of the active 3D sensor includes defining a near range distance from the active 3D sensor and defining a last echo distance from the active 3D sensor greater than said defined near range distance. The method includes receiving a sequence of echo pulses of a signal emitted by the active 3D sensor and subjecting the sequence of echo pulses to a pre-defined trigger condition such that only those echo pulses are taken into consideration which fulfill the predefined trigger condition. The method also includes determining, from the echo pulses which fulfill the predefined trigger condition and that are received from distances greater than a defined near range distance, a first echo pulse and an adaptive echo pulse, and providing distance measurements of the surroundings in front of the 3D sensor using the determined first echo pulse and the determined adaptive echo pulse.
