Method and a system for calibrating an image capture device

A method for calibrating an image capture device mounted on a vehicle for offset from at least one of an ideal position and an ideal angular orientation about a focal axis of the image capture device while the vehicle is moving, the method comprising:

• selecting an image frame captured by the image capture device as a reference image frame when image data thereof in a time domain in at least one portion of the image frame is indicative of a high spatial frequency content greater than a predefined high spatial frequency content;
• selecting, as a target image, an image of a stationary object in an environment external of the vehicle in the reference image frame suitable as a target object;
• predicting a location at which an image of the target object should appear in a subsequently captured image frame in response to at least one parameter of the moving vehicle;
• comparing the actual location of the image of the target object in the subsequently captured image frame with the predicted location thereof;
• determining from the comparison of the actual and the predicted locations of the images of the target object whether the image capture device is offset from the at least one of the ideal position and the ideal angular orientation;
• and
• determining calibration data from the difference between the actual and the predicted locations of the image of the target object for applying to image frames later captured by the image capture device for correcting the later captured image frames for the offset of the image capture device from the at least one of the ideal position and the ideal angular orientation when the image capture device is determined to be offset therefrom.
