CALIBRATION SYSTEM AND METHOD FOR VEHICULAR SURROUND VISION SYSTEM

摘要

A camera calibration method for calibrating at least one camera of a vehicle includes providing a target area for a vehicle to be positioned at, with the vehicle having a forward camera, a rearward camera and opposite side cameras. When the vehicle is positioned at the target area, a target is electronically generated at an area that is encompassed by the field of view of one of the cameras or at an overlapping portion of the fields of view of two of the cameras of the vehicle. Image data is captured by the two cameras that is representative of the generated target. Image data captured by the two cameras is processed to detect the target in the fields of view of the two cameras. At least one of the two cameras is calibrated responsive to detection of the target.

1. A camera calibration method for calibrating at least one camera of a vehicle, said camera calibration method comprising:
providing a target area for a vehicle to be positioned at, the vehicle having a forward camera, a rearward camera and opposite side cameras; when the vehicle is positioned at the target area, electronically generating a target at an overlapping portion of the fields of view of two of the cameras of the vehicle by use of light projection; capturing image data captured by the two cameras that is representative of the target at the overlapping portion; processing image data captured by the two cameras to detect the target in the overlapping portion of the fields of view of the two cameras; and calibrating at least one of the two cameras responsive to detection of the target.
