Abstract (en)

[origin: WO2022069424A1] To capture three-dimensional images with the aid of a stereo camera (55a) having two cameras (54, 55), an image of a three-dimensional scene is first captured (64) with the two cameras (54, 55) simultaneously. Characteristic signatures of scene objects within each captured image are determined (65) and assigned to each other in pairs (66). Characteristic position deviations of the assigned signature pairs from one another are determined (67). The position deviations are filtered in order to select assigned signature pairs. On the basis of the selected signature pairs, a triangulation calculation is carried out (69) to determine depth data for the respective scene objects. A 3D data map of the captured scene objects within the captured image of the three-dimensional scene is then created (70). This results in a method for capturing three-dimensional images, which is well adapted for practical use, in particular for capturing images to safeguard autonomous driving.
