Embodiment 1

[0032] An embodiment of the present invention provides a vehicle-mounted head-up display device, such as figure 1 As shown, the vehicle-mounted head-up display device includes: a navigation module, an eye position detection module, an image processing module and an image display module; wherein,

[0033] The navigation module is used to input the navigation data and the spatial position coordinates of the position (for example, a right-turn intersection) of the car relative to the navigation information to the image processing module. In this coordinate system, the position to be executed of the above-mentioned navigation information is the coordinate origin, And take the forward direction of the car as the X-axis direction, take the horizontal rightward direction of the car as the Y-axis direction, and take the vertical upward direction of the car as the Z-axis direction, for example, when the navigation data is "Turn right at the intersection 200 meters ahead ", and when the...

Embodiment approach 1

[0040] Embodiment 1, such as Figure 4 As shown, the image processing module includes a spatial light modulator 4, and the spatial light modulator 4 is connected to the navigation module and the eye position detection module respectively, and the spatial light modulator 4 is used to respectively convert the spatial position of the car relative to the position to be executed in the navigation information The coordinates, the spatial position coordinates of the driver's left eye and right eye respectively relative to the car are loaded on the optical data field of the navigation data to form display information.

[0041] In addition, if Figure 4 As shown, the image display module includes a vertical holographic lens 5, a vertical first collimator lens group 6, a tilted reflective mirror 7, a horizontal second collimator lens group 8 and a concave mirror 9, and the inclination of the reflective mirror 7 The angle is 45°, wherein the holographic lens 5 is arranged on one side of...

Embodiment approach 2

[0043] Embodiment 2, such as Figure 5 As shown, the image processing module includes a liquid crystal panel projector 10, the liquid crystal panel projector 10 is connected with the navigation module and the eye position detection module, and the liquid crystal panel projector is used for the spatial position coordinates, driving The left and right eyes of the driver process the navigation data relative to the spatial position coordinates of the car, so that the adjacent pixel columns in the LCD panel projector display the left-eye image and the right-eye image respectively, and the left-eye image and the right-eye image constitute Display information.

[0044] In addition, if Figure 5 As shown, the image display module includes a spectroscopic screen 11. The spectroscopic screen 11 is arranged on one side of the light-emitting surface of the liquid crystal panel projector 10. The spectroscopic screen 11 is used to reflect the light emitted by the pixel row displaying the i...

Abstract

The invention discloses a vehicle-mounted head-up display device and a display method, which relate to the field of display technology and are used for providing accurate navigation information for the driver when the driver's head moves left and right. The vehicle-mounted head-up display device includes: a navigation module, an eye position detection module, an image processing module, and an image display module; wherein the navigation module is used to input navigation data and the position to be executed of the car relative to the navigation information to the image processing module The spatial position coordinates of the vehicle; the eye position detection module is used to detect the spatial position coordinates of the driver's left eye and right eye respectively relative to the car; the image processing module is used to form display information; the image display module is used to display The display information is displayed in the form of an image in front of the driver's eyes, and the image is located on a straight line between the driver's eyes and a position to be executed of the navigation information. The invention is used for displaying navigation information in the process of driving a car.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a vehicle-mounted head-up display device and a display method. Background technique [0002] The vehicle-mounted head-up display device is a car driving assistance device that uses optical principles to display navigation information (for example, intersection steering information) in front of the driver's eyes during car driving. [0003] The inventors of the present application found that in the prior art, the vehicle-mounted head-up display device fixedly displays the above-mentioned navigation information on the inner side of the front windshield of the car in the form of a two-dimensional image (for example, an arrow indicating a right turn), and the above-mentioned two-dimensional The image is positioned directly in front of the eyes of the driver of the car. When the driver's head moves left and right (for example, the driver's head moves left and right due to the bumpin...
