Abstract:
A method for calibrating a camera of a vehicular vision system includes providing a camera and an image processor at the vehicle. A monoview noncoplanar three dimensional calibration pattern distributed on a semi-sphere is determined via processing of image data captured by the camera. Responsive to determination of the monoview noncoplanar three dimensional calibration pattern distributed on the semi-sphere, extrinsic parameters of the camera and intrinsic parameters of the camera are estimated. The system performs at least one of (i) a linear refinement of the estimated extrinsic parameters and intrinsic parameters and (ii) a non-linear refinement of the estimated extrinsic parameters and intrinsic parameters. Responsive to processing by the image processor of image data captured by the camera, the camera is calibrated at least in part by using the determined monoview noncoplanar three dimensional semi-spherical calibration pattern.

Claim (Index 12):
The method of  claim 11 , wherein image data captured by the camera is transferred to the electronic control unit of the vehicle via a communication link of the vehicle, and wherein the communication link comprises a vehicle network bus of the vehicle.
