AI Technical Summary
Existing head-up display systems suffer from superimposition deviations between the real view of the outside world and the virtual image due to changes in the observer's eye height, necessitating adjustments to the reflection mirror which can alter the virtual image's depression angle.
A head-up display system that adjusts the virtual image position by increasing the display area in the up-down direction without rotating the mirror, using a calibration image and a light source to align the virtual image with the observer's eye height, ensuring accurate superimposition regardless of eye position.
The system effectively reduces superimposition deviations between the real and virtual images by adjusting the display area based on the observer's eye height, maintaining a consistent positional relationship between the virtual image and the outside world view.
