Abstract
(DE)
Es wird ein LiDAR-System (1) beschrieben, das dafür eingerichtet ist, eine Umwelt mit einem Lichtstrahl abzutasten, um Informationen über die Umwelt zu erfassen. Das LiDAR-System (1) ist zudem dafür eingerichtet ist, sowohl hochreflektive Objekte in einem Nahfeld über die Umwelt als auch geringreflektierende Objekte in einem Fernfeld über die Umwelt zu erfassen, dadurch gekennzeichnet, dass das LiDAR-System (1) mehrere Photodetektoren (4) aufweist, die dafür eingerichtet sind, unterschiedliche Sättigungswahrscheinlichkeiten zu haben. Ferner wird ein Kraftfahrzeug mit einem solchen LiDAR-System (1) beschrieben, das mit dem Kraftfahrzeug wirkverbunden ist.
(EN)
The invention relates to a LIDAR system (1) which is designed to scan an environment with a light beam in order to detect information regarding the environment. The LIDAR system (1) is in addition configured to detect highly reflective objects that are close in the environment as well as low-reflecting objects in the far field of the environment, characterised in that the LIDAR system (1) comprises several photodetectors (4) which are designed to have different saturation probabilities. Furthermore, a motor vehicle having a LIDAR system (1) of said type which is operatively connected to the motor vehicle is disclosed.
(FR)
L'invention concerne un système LiDAR (1) conçu pour balayer un environnement au moyen d’un faisceau lumineux afin de détecter des informations relatives à l’environnement. Le système LiDAR (1) est conçu en outre pour détecter aussi bien des objets très réfléchissants dans un champ proche de l’environnement que des objets peu réfléchissants dans un champ lointain de l’environnement. Ce système LiDAR (1) est caractérisé en ce qu’il comprend plusieurs photodétecteurs (4) conçus pour présenter différentes probabilités de saturation. L'invention concerne en outre un véhicule à moteur équipé d'un tel système LiDAR (1) coopérant avec celui-ci.
