VEHICLE, HEAD-UP DISPLAYING SYSTEM AND METHOD FOR ADJUSTING HEIGHT OF PROJECTION IMAGE THEREOF
First Claim
1. A head-up displaying system, configured to be applied in a vehicle, and comprising:
- a projector, disposed in the vehicle, and configured to project a projection image onto a front windshield such that the projection image is reflected into eyes of a driver;
a camera, fixedly disposed in the vehicle and in front of the eyes of the driver, and configured to detect an image having locations of the eyes of the driver and a predetermined reference point;
a seat detecting module, configured to detect a position of a seat of the driver in the vehicle so as to obtain an actual horizontal distance between the eyes of the driver and the predetermined reference point in a horizontal direction; and
a head-up controller, configured to obtain the image detected by the camera and the actual horizontal distance detected by the seat detecting module, to process the image so as to obtain a position relation between the eyes of the driver and the predetermined reference point in the image, to generate an actual vertical distance between the eyes of the driver and the predetermined reference point according to the position relation and the actual horizontal distance, and to adjust a height of the projection image from the projector automatically according to the actual vertical distance.

Abstract
A vehicle, a head-up displaying system and a method for adjusting a height of a projection image thereof are provided. The system includes a projector, a camera, a seat detecting module and a head-up controller. The camera is configured to detect an image having locations of the eyes of the driver and a predetermined reference point. The seat detecting module is configured to detect a position of a seat of the driver in the vehicle so as to obtain an actual horizontal distance between the eyes of the driver and the predetermined reference point. The head-up controller is configured to adjust a height of the projection image projected by the projector automatically according to the actual vertical distance. The system automatically controls the height of the projection image, and the projection image may be comfortable for the driver to view without any manual intervenes.
