Abstract: A method for labeling vehicle-generated sensor data uses radar points from a radar detector, image data from camera(s) and lidar data from a lidar with overlapping fields-of-view. The method assigns plausibility labels to the radar points from the image data corrected by image-rectification, generates a camera-based depth estimation from a neural network calibrated by the lidar data, calculating a three-dimensional point from two-dimensional image information by the camera-based depth estimation, with the cloud being associated with the radar points and the lidar data being associated with the radar points. A radar/lidar plausibility and a radar/camera plausibility arise and are merged to form an optics-based plausibility. A radar/tracking plausibility is assigned to each radar point by tracking.

Abstract: A method for detecting movements of a body of a first motor vehicle includes recording image and sensor data by a camera and sensor device of a second motor vehicle. The image and sensor data represent that part of the environment of the second motor vehicle that contains the first motor vehicle.

The classified movements of the vehicle body are assigned to at least one of a set of defined states. Output data from the determined state are generated for further use in an automated driving function and/or for a user interface.
