Abstract

A rearview panoramic head-up display device for vehicles, which includes a camera lens input port group, a base, a display module, a detection module and a semitransparent reflective film. The camera lens set on each side outside the car are used to capture the image around the car and transmit the images to the present device inside the car. A three-dimensional rear panoramic image is formed by synthesizing the images by a panoramic display processor in the present device and projected on the windshield of the car by the display module, so that the driver may observe the real-time condition in rear, left rear and right rear of the car while looking ahead, the driver may know the condition around the car without moving the line of sight through a large angle, to thereby improve traffic safety.

Claims

1. A rearview panoramic head-up display device for vehicles, which includes:

a camera lens input port group, wherein at least three camera lens input ports are set for connecting to three camera lens respectively located on the rear, left and right sides of a car, to capture the images of surroundings in rear of the car;

a base, wherein a capacity space is set inside for placing a circuit board, the circuit board includes a panoramic display processor, the circuit board is electrically connected to the camera lens input port group, the panoramic display processor is used to join the images shot by the at least three camera lens together by using image processing techniques to form a three-dimensional panoramic image, and a display opening is set on the surface of the base;

a display module, which is electrically connected to the circuit board, and is set on the display opening to receive the images output from the circuit board to display the images as a mirror image;

a detection module, which is a light sensing unit, is electrically connected to the circuit board and is used to sense the brightness of the environment to modulate the brightness of the display module;

a semitransparent reflective film, which is pasted on the inner side of the front windshield of the car to display the image of the display module as mirror images; and

a satellite module, which is electrically connected to the circuit board, the satellite module includes a satellite positioning and map data, and a control button, the control button modulating the visual angle of the camera lens to a modulated visual angel, and the modulated visual angle of the camera lens, a location and the vehicle traveling direction is stored with the satellite positioning and map data;

wherein, when the car is initially positioned in the location, the satellite positioning and map data and the modulated visual angel of the camera lens are stored, and when the car is subsequently positioned in the location, the camera lens are automatically adjusted to a corresponding modulated visual angle that was previously saved for the location.

2. The rearview panoramic head-up display device for vehicles as claimed in claim 1, wherein the base is placed on the instrument desk of the car, or embedded into the instrument desk under the front windshield.

3. The rearview panoramic head-up display device for vehicles as claimed in claim 1, wherein the brightness of the display module is achieved at least 2500 nit.

4. The rearview panoramic head-up display device for vehicles as claimed in claim 1, further includes a satellite module, which is electrically connected to the circuit board, the satellite module includes a satellite position information, a visual angle of the camera lens is modulated as a visual range when turning in an intersection.

5. A rearview panoramic head-up display device for vehicles, which includes:

a camera lens input port group, wherein at least three camera lens input ports are set for connecting to three camera lens respectively located on the rear, left and right sides of the car, to capture the images of surroundings in rear of the car;

a base, wherein a capacity space is set inside for placing a circuit board, the circuit board includes a panoramic display processor, the circuit board is electrically connected to the camera lens input port group, the panoramic display processor is used to join the images shot by the at least three camera lens together by using image processing techniques to form a three-dimensional panoramic image, and a display opening is set on the surface of the base;

a display module, which is electrically connected to the circuit board, and is set on the display opening to receive the images output from the circuit board to display the images as a mirror image;

a detection module, which includes a reverse signal unit and an image identification unit, is electrically connected to the circuit board, when the reverse signal unit detects a reverse signal and the image identification unit detects that there is a moving car in rear of the car, a visual angle of the camera lens is modulated to a wider visual angle and displayed as said panoramic image;

when the reverse signal unit detects a reverse signal and the image identification unit detects that there is no moving car in rear of the car, the visual angle of the camera lens is modulated to a narrower visual angle and displayed as said panoramic image;

a semitransparent reflective film, which is pasted on the inner side of the front windshield of the car to display the image of the display module as mirror images.

6. The rearview panoramic head-up display device for vehicles as claimed in claim 5, wherein the base is placed on the instrument desk of the car, or embedded into the instrument desk under the front windshield.

7. The rearview panoramic head-up display device for vehicles as claimed in claim 5, wherein the brightness of the display module is achieved at least 2500 nit.

8. The rearview panoramic head-up display device for vehicles as claimed in claim 5, wherein the detection module further includes a light sensing unit, which is electrically connected to the circuit board to modulate the brightness of the display module.

9. The rearview panoramic head-up display device for vehicles as claimed in claim 5, wherein the camera lens input port group further includes a front camera lens input port, which is used to connect to a front camera lens to capture the image in front of the car.
