Calibration system and method for vehicular surround vision system
First Claim
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;
the vehicle to be positioned at the target area having a type or size of the vehicle to be positioned at the target area;
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;
configuring the target responsive to the type or size of the vehicle to adapt the target, when the target is electronically generated at the target area, for the particular type or size of the vehicle positioned at the target area;
capturing image data via the two cameras that is representative of the target electronically generated at the overlapping portion;
processing image data captured by the two cameras to detect the target that is electronically generated at 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 that is electronically generated at the target area.

Abstract
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.
