Vehicle device, and non-transitory tangible computer readable medium

A vehicle device that notifies a driver of information using a projection device that displays an image on a projection surface, the vehicle device comprising:

• an image generation unit that generates the image to be notified to the driver in a predetermined reference coordinate system;
• a viewpoint position identification unit that identifies a viewpoint position of the driver indicative of a positional relationship between a position of the driver's eye in a vehicle compartment and the projection surface, the position of the driver's eye being detected by and received from a viewpoint detection unit that detects the position of the driver's eye using image processing;
• a superimposed position identification unit that identifies a display position, at which the image generated by the image generation unit is displayed within an eyesight of the driver, based on the viewpoint position of the driver;
• an image conversion unit that generates a converted image obtained by converting the image generated by the image generation unit into a coordinate system having the viewpoint position of the driver as a reference point;
• and
• a notification unit that notifies the driver of the information by displaying the converted image to be superimposed on the eyesight of the driver with the projection device;
• wherein:
• the image conversion unit corrects the converted image according to the viewpoint position of the driver;
• and
• the notification unit displays a corrected converted image to be superimposed within the eyesight of the driver.

• wherein:
• the image conversion unit reconverts the image generated by the image generation unit according to a movement of the viewpoint position of the driver.

A non-transitory tangible computer readable medium comprising instructions being executed by a computer, the instructions including a computer-implemented method for controlling a control unit for a vehicle device, which notifies a driver of information using a projection device that displays an image on a projection surface the instructions including:

• generating the image to be notified to the driver in a predetermined reference coordinate system;
• identifying a viewpoint position indicative of a positional relationship between a position of the driver's eye in a vehicle compartment and the projection surface, the position of the driver's eye being detected by and received from a viewpoint detection unit that detects the position of the driver's eye using image processing;

• generating a converted image obtained by converting the image generated by the image generation unit into a coordinate system having the viewpoint position of the driver as a reference point;
• notifying the driver of the information by displaying the converted image to be superimposed on the eyesight of the driver with the projection device;
• correcting the converted image according to a shape of the projection surface;
• and
• displaying a corrected converted image to be superimposed within the eyesight of the driver.

• generating a reference image to be notified in a predetermined reference coordinate system;
• identifying a viewpoint position indicative of a positional relationship between a position of an eye of a person disposed in a driver's seat and the projection surface, the position of the eye being detected by and received from a viewpoint detection unit that detects the position of the eye of the person disposed in the driver's seat using image processing;
• identifying a display position, at which the image generated by the image generation unit is displayed within an eyesight based on an identified viewpoint position;
• generating a converted image obtained by converting the image generated by the image generation unit into a coordinate system having the viewpoint position of the person disposed in the driver's seat based on the identified viewpoint position;
• displaying the converted image to be superimposed on the eyesight of the driver with the projection device;
• correcting distortion of a displaying image according to an operation of the person disposed in the driver's seat;
• acquiring a correction amount when correcting the distortion of the image;
• designing a coordinate conversion filter in which the correction amount at the viewpoint position is identified by connecting an acquired correction amount and the viewpoint position to each other
• correcting the converted image according to a shape of the projection surface;
• and
• displaying a corrected converted image to be superimposed within the eyesight of the driver.
