Abstract
(DE) Gemäß verschiedenen Ausführungsformen kann ein LIDAR-System (100) aufweisen: einen Detektor (102) aufweisend eine Mehrzahl von Detektorpixeln (104), welche derart eingerichtet sind, dass sie ein Lichtsignal detektieren, wobei die Detektorpixel (104) in einem zweidimensionalen Array (106) angeordnet sind, ein Lichtemissionssystem (114), welches derart eingerichtet ist, dass es ein Lichtsignal (116) in ein Sichtfeld (118) des LIDAR-Systems (100) aussendet, und ein oder mehrere Prozessoren (124), welche derart eingerichtet sind, dass sie ein erstes detektiertes Lichtsignal (126-1), welches von einem ersten Satz (104-1) von Detektorpixeln (104) der Mehrzahl von Detektorpixeln (104) bereitgestellt wird, einer direkten Reflexion des ausgesendeten Lichtsignals (116) zuordnen, und dass sie ein zweites detektiertes Lichtsignal (128-1), welches von einem zweiten verschiedenen Satz (104-2) von Detektorpixeln (104) der Mehrzahl von Detektorpixeln (104) bereitgestellt wird, einem Lichtsignal (130) anders als die direkte Reflexion des ausgesendeten Lichtsignals (116) zuordnen.
(EN) According to various embodiments, a lidar system (100) may comprise: a detector (102) comprising a plurality of detector pixels (104) which are configured such that they detect a light signal, the detector pixels (104) being arranged in a two-dimensional array (106), a light-emission system (114) which is configured such that it emits a light signal (116) into a field of view (118) of the lidar system (100), and one or more processors (124) which are configured such that they assign a first detected light signal (126-1), which is provided by a first set (104-1) of detector pixels (104) of the plurality of detector pixels (104), to a direct reflection of the emitted light signal (116) and such that they assign a second detected light signal (128-1), which is provided by a second different set (104-2) of detector pixels (104) of the plurality of detector pixels (104), to a light signal (130) that differs from the direct reflection of the emitted light signal (116).
