CALIBRATION METHOD AND CALIBRATION SYSTEM FOR A RAILWAY VEHICLE CAMERA, AND RAILWAY VEHICLE HAVING RAILWAY VEHICLE CAMERA

摘要

In order to calibrate a railway vehicle camera (BFZK) easily and cost-effectively, it is proposed that - a plurality of reference images (RBI) of a line (BST), in particular a railway line (SST), in relation to a route area (FSB) ahead of a rail vehicle (BFZ, SFZ) which represent the route area (FSB) are captured and stored by the railway vehicle (BFZ), in particular rolling stock (SFZ), - metadata (MD) regarding the line (BST, SST) captured in the images are present, - a calibration image (KBI_MD) of a portion of the line (BST, SST) which is determinable on account of the metadata (MD) and has a linear course of a lane is captured by the railway vehicle camera (BFZK), - information specifying the position and orientation, what is known as the pose, of the railway vehicle camera (BFZK) in relation to the lane is determined in the calibration image (KBI_MD) on the basis of the lane course, - a correction value (KW) is calculated on the basis of a metadata-based reference image (RBI_MD) of the reference images (RBI) corresponding to the calibration image (KBI_MD) as difference value in relation to a reference position in the metadata-based reference image (RBI_MD) on the basis of the pose information, - the calculated correction value (KW) is used to generate camera calibration information (KKI) or to interpret the image information in the calibration image (KBI_MD).
