Automotive rearview panorama head-up display device

Abstract

The invention discloses an automotive rearview panorama head-up display device. The display device comprises a pick-up lens input port group, a base seat, a display module, a detection module and a semitransparent reflective sheet. According to the device, images of the environment around and outside a vehicle are captured with photographic lenses mounted on all sides of the outer part of the vehicle, transmitted to the device inside the vehicle, synthetized into a three-quadrant rear panorama image through a panorama display processor in the device and projected to an auto windshield via the display module, so that a driver can observe a real-time status of the rear, left rear and right rear corners of the vehicle while staring at the front, and can grasp the conditions around and outside the vehicle without moving the line of sight at a wide angle; the driving safety is significantly improved.

Description

technical field [0001] The invention relates to a rear view head-up display device for a vehicle, in particular to a rear view head-up display device for a vehicle that can synthesize multiple images into a three-quadrant rear image, so as to provide the driver with no need to move at a large angle Under the line of sight, you can grasp the surrounding scenery outside the car, which greatly improves driving safety. Background technique [0002] When the vehicle is moving, it is necessary not only to pay attention to the front environment at all times, but also to pay attention to the vehicles coming from the rear from time to time.

Problems solved by technology

[0009] As mentioned above, this head-up display technology has been widely used in automobiles, and there are many related patent cases, such as TW M425068 (hereinafter referred to as cited case 1) and TW I305757 (hereinafter referred to as cited case 2), among which Citation Case 1 (eg figure 1 As shown), it includes: at least one image capture unit 10 for monitoring the driving dynamics outside the vehicle and generating at least one dynamic image; and a head-up display unit 20 including an image projection module 21 for projecting the image , and an image reflection module 22 covering a front windshield of the vehicle, the image reflection module 22 is used to reflect the light and shadow of the image, and with the assistance of the light and shadow, the driving dynamics of the vehicle can be monitored. It is disclosed that a plurality of camera heads 11, 12, 13, 14 are used to shoot images outside the vehicle, and the images are output to the head-up display unit 20; Citation 1, although images taken from multiple directions can be captured, the head-up display unit The picture reflected by the display unit 20 can only display one of the pictures according to the driving situation. or one-sided) image, and can not really provide the driver with the panoramic image around the vehicle in time, so there are still blind spots in the line of sight
