Abstract

A method and an apparatus are for adapting image processing based on a shape of a display device for a motor vehicle. The apparatus includes: a capture device configured to capture a shape of a display device, an extrinsic camera parameter of a camera, an intrinsic camera parameter of the camera, and a of view of the camera; an arithmetic unit configured to calculate a reprojection surface and a correspondence table based on the captured shape of the display device, the extrinsic camera parameter, the intrinsic camera parameter, and the field of view; and an image processing device configured to perform adapted image processing that is adapted based on the reprojection surface and the correspondence table.

First claim

The invention claimed is:

1. An apparatus comprising:
a capture device configured to capture a shape of a display device of an A-pillar of a motor vehicle, an extrinsic camera parameter of a camera, an intrinsic camera parameter of the camera, and at least one field of view of the camera;
an arithmetic unit configured to calculate a reprojection surface and a correspondence table based on the shape of the display device, the extrinsic camera parameter, the intrinsic camera parameter, and the at least one field of view; and
an image processing device configured to perform adapted image processing that is adapted based on the reprojection surface and the correspondence table.

2. The apparatus according to claim 1 , wherein the shape of the display device comprises a curvature of the display device, and the arithmetic unit is configured to calculate the reprojection surface to compensate the curvature of the display device.

3. The apparatus according to claim 1 , wherein the arithmetic unit is configured to calculate the reprojection surface based on a projected display grid.

4. The apparatus according to claim 3 , wherein the arithmetic unit is configured to generate the projected display grid on a subarea of the field of view.

5. A method comprising the steps:
capturing a shape of a display device of an A-pillar of a motor vehicle by a capture device;
capturing an extrinsic camera parameter of a camera, an intrinsic camera parameter of the camera, and at least one field of view of the camera by the capture device;
calculating a reprojection surface and a correspondence table based on the shape of the display device, the extrinsic camera parameter, the intrinsic camera parameter, and the at least one field of view of the camera by an arithmetic unit; and
performing an adapted image processing that is adapted based on the reprojection surface and the correspondence table by an image processing device.

6. The method according to claim 5 , wherein the shape of the display device comprises a curvature of the display device, and the reprojection surface is calculated to compensate the curvature of the display device.

7. The method according to claim 5 , wherein the reprojection surface is calculated based on a projected display grid.

8. The method according to claim 7 , wherein the projected display grid is generated on a subarea of the field of view.
