Problems solved by technology

This processing method has certain disadvantages: the projected image is separated from the actual road. Although the driver can see the driving information without looking down, he still needs to be distracted to match the information he sees with the actual road conditions. Combining the instructions with the actual road conditions, there are still certain potential safety hazards

Embodiment Construction

[0033] Embodiments of the present invention will be described in detail below. It should be emphasized that the following description is only exemplary and not intended to limit the scope of the invention and its application.

[0034] refer to Figure 1 to Figure 3 , in one embodiment, a kind of system that realizes car driving information display based on vehicle-mounted GPS and reflection principle, comprises the projector 101 that is used for projecting virtual line pointing image, is used for obtaining driver's eyeball position information ( not shown), and the automobile windshield 102. In the system, a space Cartesian coordinate system O-XYZ is established based on the position of the car, wherein the direction of the driver's seat perpendicular to the ground is the Z-axis, the direction of the car is the X-axis, and the direction perpendicular to the Z-axis and the X-axis is the Y axis; under the spatial rectangular coordinate system O-XYZ, the plane β where the proje...

Abstract

The invention discloses a system and a method for realizing automotive driving information display. The system comprises a projector for projecting a virtual circuit indicating image, an eyeball tracking instrument for acquiring driver's eyeball position information, and an automotive windshield glass. According to the system, the human eye vision principle is adopted, and a method integrating a light reflection principle and a mirror imaging principle is used, so that the virtuality and reality combined three-dimensional display of an automotive forward driving direction indicating arrow and an actual road condition is realized; through the adoption of the method and the system, the visual effect that the indicating arrow in the automotive driving direction is fit with a driving pavement can be given to an automotive driver.

Description

technical field [0001] The invention relates to a system and method for realizing the display of vehicle driving information based on vehicle GPS and reflection principle. Background technique [0002] HUD is the abbreviation of HeadUpDisplay. It was used on fighter jets before, and later some automobile manufacturers also used it, but it is not widely used. The realization principle of the HUD on the car is mainly to use the principle of optical reflection to project the vehicle and driving related information on the glass, the coated lens, and then reflect it into the driver's eyes. In this way, the driver can see the driving information without having to lower his head, such as vehicle speed, navigation, etc., will be displayed in a small area of ​​the front windshield, so as to avoid distracting the driver's attention to the road ahead. [0003] The existing car HUD mainly simply projects the car and driving information on the windshield. This processing method has cer...
