Title (EN) LIDAR SYSTEMS AND METHODS
(FR) SYSTÈMES ET PROCÉDÉS DE DÉTECTION ET LOCALISATION PAR LA LUMIÈRE
Abstract:
(EN) In some embodiments, a LIDAR system may include at least one processor configured to control at least one light source for projecting light toward a field of view and receive from at least one first sensor first signals associated with light projected by the at least one light source and reflected from an object in the field of view, wherein the light impinging on the at least one first sensor is in a form of a light spot having an outer boundary. The processor may further be configured to receive from at least one second sensor second signals associated with light noise, wherein the at least one second sensor is located outside the outer boundary; determine, based on the second signals received from the at least one second sensor, an indicator of a magnitude of the light noise; and determine, based on the indicator the first signals received from the at least one first sensor and, a distance to the object.
(FR) Dans certains modes de réalisation, la présente invention concerne un système de détection et localisation par la lumière (LIDAR) pouvant comprendre au moins un processeur configuré pour commander au moins une source de lumière pour projeter de la lumière vers un champ de vision et recevoir en provenance d'au moins un premier capteur des premiers signaux associés à la lumière projetée par la ou les sources de lumière et réfléchie par un objet dans le champ de vision, la lumière incidente sur le ou les premiers capteurs se présentant sous la forme d'un point lumineux présentant une limite externe. Le processeur peut en outre être configuré pour recevoir en provenance d'au moins un second capteur des seconds signaux associés au bruit lumineux, le ou les seconds capteurs étant situés à l'extérieur de la limite externe ; déterminer, sur la base des seconds signaux reçus en provenance du ou des seconds capteurs, un indicateur d'une amplitude du bruit lumineux ; et déterminer, sur la base de l'indicateur et des premiers signaux reçus en provenance du ou des premiers capteurs, une distance par rapport à l'objet.
