Automotive windshield type head-up display based on multi-picture division technology

Abstract

The invention discloses an automotive windshield type head-up display based on a multi-picture division technology in the field of vehicle-mounted head-up display equipment. The automotive windshield type head-up display comprises a device body and an HUD (head up display) application system, wherein the device body comprises a storage module, an MCU (micro control unit) micro control module, a wireless transmission module, an audio and video entertainment control module, an image generation module, a display control module, a micro projection module and a miniature three-dimensional scanner, wherein the storage module, the image generation module, the audio and video entertainment control module, the display control module, the micro projection module, the wireless transmission module and the miniature three-dimensional scanner are connected onto the MCU micro control module; the miniature three-dimensional scanner is connected with the MCU control module; the MCU micro control module transmits curvature information to the display control module; the display control module integrates the curvature information and the image information and transmits image data with curvature through the micro projection module, so that the image is further inclined; and the HUD application system comprises a communication application system and a road navigation system. The automotive windshield type head-up display disclosed by the invention can be applied to the existing automobile repacking.

Description

technical field [0001] The invention relates to a vehicle head-up display, in particular to an automotive windshield type head-up display. Background technique [0002] In the prior art, an automobile windshield head-up display (also called an automobile windshield head-up display, hereinafter referred to as HUD) is an electronic display device composed of electronic components, display components, control components, and the like. It can project a variety of information data in the form of images and characters through optical components on the windshield of the car, so that drivers can see all kinds of information they need without looking down during the driving process. Under normal circumstances, if the driver's eyes look away from the front when driving, it is very easy to cause a car accident. Usually, it takes at least 0.5 seconds for the driver to lower his head to read the information on the navigation or mobile phone. If this situation occurs at high speed or whe...

Problems solved by technology

According to the search of related domestic scientific and technological literature, through the use of multi-screen segmentation technology, the car windshield-type head-up display that can display multi-region image screens (multi-screen) can be realized; Communication application system connection, which can realize the adjustment of projection image height, brightness and screen projection area, and can realize the free switching display of multiple interfaces such as basic driving interface, navigation interface, and call interface. There are still few reports so far.

At the same time, due to the limitation of the curved surface of the windshield, the HUD equipment in the prior art is not easy to display large images realistically, and generally only displays some simple data such as vehicle speed and fuel level.
