The present invention provides a roll angle calibration method for a camera (101), the method comprising recording (S1) an image (102, 200, 300, 400) with the camera (101), extracting (S2) vertical lines (105, 201, 202, 203, 301, 302, 303, 401, 402, 403) that are vertical within a predetermined tolerance in the recorded image (102, 200), and calculating (S3) the roll angle (107) of the camera (101) based on the extracted vertical lines (105, 201, 202, 203, 301, 302, 303, 401, 402, 403). Further, the present invention provides a corresponding roll angel calibration device.
