In a system and a method for extrinsic calibration of an image capture system of a vehicle, the vehicle includes a body and a body portion, wherein the body portion is configured to rotate around a rotation axis relative to the vehicle. The system includes an image capture system with an image capture device mounted on the body portion and adapted to capture at least two images of the body and/or surrounding area of the vehicle, an identification unit adapted to identify at least two image features in the images, a calculation unit adapted to calculate a direction of the rotation axis relative to the image capture device based on the image features, and a calibration unit configured to determine extrinsic parameters of the image capture system based on the calculated direction of the rotation axis relative to the vehicle. The image capture system is calibrated using degrees of freedom of movement that the image capture device has due to being mounted on a movable portion of the vehicle.
