Method and apparatus for calibrating an image capturing device, and a method and apparatus for outputting image frames from sequentially captured image frames with compensation for image capture device offset |
摘要 |
A camera (17) mounted on a rear view minor housing (5) of a vehicle (1), which captures a plan view image of the ground on one side of the vehicle for display on an in-vehicle visual display unit (13) is calibrated to correct for offset of the camera (17) from an ideal position. During calibration an image of a reference point (34) on the vehicle (1) is captured as the mirror housing (5) is swiveled from a rest position to an operative position. The offset of the actual position of the image of the reference point in the captured image from its ideal position is computed, and a look-up table is prepared, which indicates the position at which pixels of subsequently captured image frames should be located to produce image frames with offset correction.
