POSITION ADJUSTMENT METHOD OF VEHICLE DISPLAY DEVICE
First Claim
1. A position adjustment method of a vehicle display device including:
- a display device configured to display a virtual image on a front field of view of a driver, anda viewpoint detecting camera configured to capture an image of the driver, the method comprising;
installing a measuring camera in a position at which a calibration pattern for acquiring information for the virtual image and position adjustment can be captured, and disposing the calibration pattern in a predetermined position with respect to a viewing angle of the virtual image, an angle of view of the viewpoint detecting camera, and an angle of view of the measuring camera;
capturing the calibration pattern by the viewpoint detecting camera and the measuring camera;
capturing the virtual image by the measuring camera;
calculating a relative position and a relative orientation between the measuring camera and the viewpoint detecting camera, and calculating a relative position and a relative orientation between the measuring camera and the display device by using an image captured by the viewpoint detecting camera and an image captured by the measuring camera, and calculating a relative position and a relative orientation between the viewpoint detecting camera and the display device from the two relative positions and orientations as orientation information; and
adjusting a position of the virtual image displayed by the display device by using the orientation information.

Abstract
In a vehicle display device including a HUD that displays a virtual image on a front field of a view of a driver and a viewpoint detecting camera that captures an image of the driver, a measuring camera is capable of capturing the virtual image. A calibration pattern is at a predetermined position with respect to a viewing angle of the virtual image and angles of view of the viewpoint detecting and measuring cameras. The calibration pattern is captured by the viewpoint detecting and measuring cameras, and the virtual image is captured by the measuring camera. The relative position and orientation between the viewpoint detecting camera and HUD are calculated as orientation information using an image captured by the viewpoint detecting camera and an image captured by the measuring camera. In addition, the position of the virtual image displayed by the HUD is adjusted using the calculated orientation information.

7. A position adjustment method of a vehicle display device including:
-
a display device configured to display a virtual image on a front field of view of a driver, and a viewpoint detecting camera configured to capture an image of the driver, the method comprising; installing a measuring camera configured to capture the virtual image, and capturing by the viewpoint detecting camera a calibration pattern for acquiring information for position adjustment, the calibration pattern being attached to a predetermined position with respect to the measuring camera; capturing the virtual image by the measuring camera; calculating a relative position and a relative orientation between the measuring camera and the viewpoint detecting camera, and calculating a relative position and a relative orientation between the measuring camera and the display device by using an image captured by the viewpoint detecting camera and an image captured by the measuring camera, and calculating a relative position and a relative orientation between the viewpoint detecting camera and the display device from the two relative positions and orientations as orientation information; and adjusting a position of the virtual image displayed by the display device by using the orientation information.
