    摘要: The invention relates to a method for operating a lidar sensor system (2) with multiple detection channels (3a-3p) for a motor vehicle (1), including a) scanning an environment (5) of the lidar sensor system (2) with a scanning light of the lidar sensor system (2); including b) measuring a transit time of a reflected light portion of the scanning light for each detection channel (3a-3p) and ascertaining a respective distance (d1-d4) of an object point (P1-P4) for each detection channel (3a-3p) depending on the measured transit time; including c) measuring an intensity (11-14) of the reflected light portion of the scanning light for each detection channel (3a-3p) and associating the respective intensity (I1-I4) with the object point (P1-P4) respectively corresponding to the detection channel (3a-3p); including d) associating multiple object points (P1-P4) with an object (7) in the environment (5) of the lidar sensor system (2); and including e) ascertaining a central point (8) of the object (7) depending on the intensity (11-14) of the object points (P1-P4) associated with the object (7), to improve an effective resolution, in particular an effective angular resolution, of the lidar sensor system (2).

    摘要: A light detection and ranging (LiDAR) system 100; 200 includes light sources 302 configured to generate separate beams of light 104, a lens array 106 configured to receive the separate beams of light 104 from the light sources 302 and to collimate the separate beams of light 104 into collimated outgoing light 108 that is directed toward an examined area of interest, a light sensitive detector 126; 208 configured to sense reflection of at least part of the collimated outgoing light 108, and one or more processors 130 configured to determine a distance to one or more objects off which the at least part of the collimated outgoing light 108 was reflected toward the light sensitive detector. The one or more processors 130 are configured to determine the distance based on the reflection of the at least part of the collimated outgoing light 108.
