Abstract
Calibrating a camera and/or a lidar sensor of a vehicle or a robot involves a camera capturing images of a vehicle or robot environment. The lidar sensor emits a real pattern into the vehicle or robot environment in at least one portion of a detection range of the camera, and the real pattern is captured by the camera. A virtual pattern generated in a coordinate system of the lidar sensor is projected onto a virtual plane in the vehicle or robot environment by the lidar sensor. Laser radiation emitted by the lidar sensor penetrates the virtual plane and the real pattern correlating with the virtual pattern is generated on a real projection surface. The real pattern captured by the camera is recalculated onto the virtual plane based on a surface profile of the real projection surface. A rectified virtual pattern is generated in a coordinate system of the camera and the camera and/or lidar sensor is/are calibrated by comparing the virtual pattern and the rectified virtual pattern.
