Vehicle-mounted augmented reality head-up display system and display method

Abstract

The invention discloses a vehicle-mounted augmented reality head-up display system and a display method. The display system comprises a camera, an image controller and an augmented reality head-up display device, wherein the augmented reality head-up display device comprises a main reflector, a secondary reflector and an image generator, the image controller converts the left eye position information acquired by the camera into a left eye position coordinate value and converts the right eye position information into a right eye position coordinate value, and the image controller performs pre-distortion processing on the left eye image according to the left eye position coordinate value to obtain a left eye pre-distortion image; pre-distortion processing is conducted on the right eye image according to the right eye position coordinate value to obtain a right eye pre-distortion image so as to ensure that the distortion degrees of a left eye virtual image seen opposite to the light path at any position in the eye box by the left eye and a right eye virtual image seen opposite to the light path at any position in the eye box by the right eye are the same; a problem that people feel dizzy after the left eye and the right eye see two images with different distortions and are subjected to brain processing is effectively solved.

Description

technical field [0001] The invention relates to the technical field of automotive electronics, and more particularly, to a vehicle-mounted augmented reality head-up display system and a display method. Background technique [0002] Head-up display devices were used in aircraft flight aids in the early days. With the development of automotive electronic technology, head-up display devices have also been gradually used in cars. The head-up display device includes: an image generator, a primary reflector and a secondary reflector, and the image generated by the image generator reaches the position of the eye box through the secondary reflector, the primary reflector and the reflection on the inner surface of the front windshield in turn, wherein the eye box is located. The box refers to the moving range of the human eye. The driver's eyes can see a virtual image several meters in front of the car in the eye box against the light path. The virtual image can display information s...
