Abstract
A calibration system for calibrating a LIDAR sensing system of a vehicle includes a plurality of light reflecting targets disposed at a ground surface at an end of line calibration region of a vehicle assembly facility. The light reflecting targets are arranged at the ground surface in a predetermined pattern. When a vehicle equipped with a LIDAR sensing system is at the calibration region, the light reflecting targets are in the field of sensing of at least one LIDAR sensor of the LIDAR sensing system of the vehicle. Responsive to processing of data sensed by the at least one LIDAR sensor, the calibration system determines the locations of the light reflecting targets and determines misalignment of the LIDAR sensor and calibrates the LIDAR sensing system to accommodate the determined misalignment.
