Surround View System Camera Automatic Calibration
First Claim
1. Logic for calibrating a surround view system of an object, configured to:
- position a set of markers on a plane at least partially surrounding the object, where the plane is in a field of view of a camera, where the camera comprises a predetermined intrinsic calibration, and where the camera is part of the surround view system;
determine a first plurality of extrinsic parameters of the camera with respect to the set of markers, where the set of markers comprises an origin and the first plurality of extrinsic parameters includes a reference to the origin; and
repeat the positioning of the set of markers and the determination of the first plurality of extrinsic parameters for at least one other camera of the surround view system.

Abstract
A system for calibrating a surround view system of an object, such as a vehicle. The system may be implemented via calibration logic that may include software, hardware, firmware, or a combination thereof. The system may include positioning a set of markers on a plane at least partially surrounding the object. The plane may be in a field of view of a camera of the surround view system, and the camera may include a predetermined intrinsic calibration. The system may also include determining a first plurality of extrinsic parameters of the camera with respect to the set of markers. The system may repeat the positioning of the set of markers and the determination of the first plurality of extrinsic parameters for at least one other camera of the surround view system.

13. A surround view system, comprising:
-
a plurality of cameras; a control unit linking the cameras to calibration logic; and where the calibration logic is configured to; position a set of markers on a plane at least partially surrounding an object, where the plane is in a field of view of a camera of the plurality of cameras, and where the camera comprises a predetermined intrinsic calibration; determine a first plurality of extrinsic parameters of the camera with respect to the set of markers, where the set of markers comprises an origin and the first plurality of extrinsic parameters includes a reference to the origin; and repeat the positioning of the set of markers and the determination of the first plurality of extrinsic parameters for at least one other camera of the plurality of cameras. - View Dependent Claims (14, 15, 16)

17. A method comprising:
-
positioning a set of markers on a plane, where the plane at least partially surrounds an object, where the plane is in a field of view of a camera that is part of a surround view system hosted by the object, and where the camera comprises a predetermined intrinsic calibration; determining a first plurality of extrinsic parameters of the camera with respect to the set of markers, where the set of markers comprises an origin and the first plurality of extrinsic parameters includes a reference to the origin; and repeating the positioning a set of markers and the determining a first plurality of extrinsic parameters for at least one other camera of the surround view system. - View Dependent Claims (18, 19, 20)
