HUD system and image adjusting method thereof

Abstract

The invention provides an HUD system which comprises an image acquisition module, an image adjusting and controlling module and a head-up display module, wherein the image acquisition module comprises a first camera, of which the output end is coupled to the input end of the image adjusting and controlling module, the first camera acquires driver's view information and sends the driver's view information to the image adjusting and controlling module, the output end of the image adjusting and controlling module is coupled to the input end of the head-up display module, the image adjusting and controlling module receives the driver's view information, generates corresponding control signals according to the driver's view information and sends the control signals to the head-up display module, and the head-up display module adjusts the image displaying position according to the control signals. The HUD system provided in the invention can track view information of a driver on a real-time basis and automatically adjust displayed images.

Description

technical field [0001] The invention relates to the technical field of vehicle equipment, in particular to a HUD system and an image adjustment method thereof. Background technique [0002] The HUD (Head Up Display) system currently on the market is basically just an extension of the car dashboard. Its main function is to display information on the dashboard, such as vehicle speed, rotation speed, etc. In addition, some high-end products can recognize signs, such as Speed ​​limit signs, etc., and some high-end products can display navigation information. [0003] But these products basically have some problems: [0004] (1) The rear-mounted HUD is basically projected on a semi-reflective glass (or other materials), which interferes with the driver to a certain extent; [0005] (2) The visual range is small, and the projection information can only be seen at a specific angle. Once the driver's head deviates or shakes, the image or the completed image will not be seen, and i...

AI Technical Summary

Problems solved by technology

[0004] (1) The rear-mounted HUD is basically projected on a semi-reflective glass (or other materials), which interferes with the driver to a certain extent;

[0005] (2) The visual range is small, and the projection information can only be seen at a specific angle. Once the driver's head deviates or shakes, the image or the completed image will not be seen, and it can only be done manually. The distance and position of the image can be adjusted accurately and cannot be actively adjusted according to the driver's sitting posture and position. During the driving process, when the driver's head position changes or the sitting posture is adjusted, the image position needs to be manually adjusted again. Security risks;

[0006] (3) During the driving process, the higher the vehicle speed, the higher the line of sight of the human eye, which is equivalent to moving the line of sight upward. If the size and position of the image are not adjusted accordingly, the experience of the HUD will be affected to a certain extent, but now Some HUDs cannot be adjusted according to information such as vehicle speed;

[0007] (4) The displayed image cannot be automatically adapted according to the vehicle width and other information;

[0008] (5) The navigation information cannot be adjusted according to the actual situation of the road, which is relatively rigid
