AR HUD Combined With 3D Image Technology To Achieve Safe Driving
Virtual reality (VR) and augmented reality (AR) are common 3D virtual image technologies in recent years. The difference between the two is that VR creates a 360 degree virtual world and immerses your perception of it through wearable devices; Augmented reality (AR) superimposes information, images, video and audio on the real environment in the form of virtual images to increase the interaction between visual effects and the environment.
Application of optical projection in automotive industry
In the application of the automotive industry, VR is mainly used for vehicle display experience and driving simulation experience. And AR is applied to the augmented head-up display (HUD) to increase the rich driving experience and improve driving safety.
When optical projection technology is integrated into the automobile industry, many different software and hardware technologies are needed as the basis. The important items in the design include vision, brightness, energy consumption and volume.
AR technology provides 3D image content
When projection technology is applied to vehicle HUD, it is most important to overcome the surrounding environment and avoid image blurring. AR technology improves the 2D image of the original HUD to 3D image information, combines the virtual image of the HUD with the actual scene, solves the problem that information obscured roads and signs in the past, and makes the extended image display not limited to the front window. With the detection of sensors, navigation, road signs, road markings, etc. can also be accurately fitted on the road.
3D AR HUD increases driving vision
The virtual image’s field of view (FOV) can be more than 20 degrees, and the virtual image display (VID) can be from the nearest 5 meters to 35 meters. The driver’s line of sight can be moved from the cluster to the front windshield to increase the driving field of vision. The 3D virtual images are integrated with reality, and the images no longer “float” in front of the line of sight, but “follow” on the objects that need to be recognized in front. It can also avoid visual fatigue, dizziness and other problems that affect driving caused by image shaking.
LBS solution is better than other HUD solution
FIC 3D AR HUD adopts the LBS technique, which has the characteristics of high contrast and brightness. Even when driving under natural light, in fog with unclear vision, in heavy rain, or even at night, its brightness, color, clarity, contrast, ghost, etc. are better than other projected techniques of HUD.
The HUD is to put a projector into the vehicle. Its volume depends on the optical path design, as well as the integration of various information and software and hardware. The volume design of the LBS solution can be controlled within 10L when the VID is 7 meters. In addition, the light source of LBS solution has high brightness application of optical projection in automobile industry and low power consumption characteristics, which can reduce heat dissipation and reduce the design volume of energy management, so that AR HUD Ar Head Up Display can be installed with the minimum volume.
Entrance of metaverse in the vehicle｜Augmented Reality HUD
The 3D image technology improves the way in which drivers receive environmental information while driving, which helps to improve driving safety and convenience. In addition to the VR and AR technologies mentioned above, there are also mixed reality (MR) and extended reality (XR). All reality image applications are closely related to future scientific and technological life. And 3D AR HUD is a system that provides safe driving of vehicles during the gradual transition from manual driving to full automatic driving. In the future, when it comes to automatic driving, the combination of virtual images and the Internet of vehicles will be an important key to realize the metaverse in the vehicle.
