Problems solved by technology

[0003] Due to the high cost of the existing vehicle display equipment, and the larger the display screen, the higher the operating temperature, the high operating temperature will affect the normal operation of the equipment, therefore, the existing HUD projected on the windshield The image is small and the imaging distance is short, so the driver still needs to look away when watching the image
[0004] For the above-mentioned problem that the image projected by the HUD on the windshield is small and the distance is relatively short, no effective solution has been proposed so far

Abstract

The invention provides a vehicle-mounted head up display device, system and augmented reality method thereof. The vehicle-mounted head up display device comprises a display device and a mirror plane, and is characterized in that the display device comprises a set of display screens arranged in an array mode, and the set of display screens comprises multiple display screens; each display screen is connected with a vehicle-mounted imaging processing device and used for receiving driving identification signals outputted by the vehicle-mounted imaging processing device, wherein the driving identification signals received by the display screens are combined into a complete driving identifier; and the driving identification signals received by each display screen are reflected by the mirror plane for one time or multiple times to vehicle wind screen glass so as to display the complete driving identifier. The embodiment of the invention enables an image projected by an HUD (head up display) on the wind screen glass to be large and long in distance.

Description

technical field [0001] The invention relates to the technical field of vehicle displays, in particular, to a vehicle head-up display device, system and augmented reality method thereof. Background technique [0002] Head Up Display, or HUD for short, is a driving assistance device used in aircrafts and automobiles. The above-mentioned HUD uses the principle of optical reflection to project important driving-related information on the windshield in front of the driver. The height of the windshield is roughly the same as the height of the driver's eyes. The text and images projected by the HUD can be adjusted in the driver's field of vision during normal driving, so that the driver does not need to look down at the display and data of the instrument, and always keep his head up. Posture, reduce the delay and discomfort caused by ignoring the rapid changes in the external environment between lowering the head and raising the head, and the need for constant adjustment of the ey...
