AR projection system and projection method used for safe driving of vehicle

Abstract

The invention provides an AR projection system and projection method used for safe driving of a vehicle. The system comprises a radar assembly, an infrared thermal imaging sensor assembly, an augmented reality control center and a holographic projection device. The radar assembly and the infrared thermal imaging sensor assembly are used for acquiring distance, heat and shape information of objects before the vehicle. The augmented reality control center is connected with the radar assembly and the infrared thermal imaging sensor assembly and used for generating a real-time 3D map and determining the nature of objects. The nature of the 3D map and the objects are combined for generating virtual image data with a prompt message. The holographic projection device is connected with the augmented reality control center and used for generating corresponding projection rays according to virtual image data and irradiating the projection rays before the vehicle. Virtual images with the safety instruction information are projected to corresponding objects. The AR projection system and projection method used for safe driving of the vehicle have the following beneficial effects: AR technology and holographic projection technology are utilized for directly projecting the virtual images with the safety instruction information before the vehicle, which helps a user drive within the range of safe distance and vehicle speed; and the AR projection system and projection method are especially adapted to nights, rainy snowy and smog days.

Description

technical field [0001] The invention relates to a vehicle display technology, in particular to an AR projection system and a projection method for safe driving of a vehicle. Background technique [0002] Safe driving of vehicles is an urgent problem to be solved in the automotive industry. Safe driving of vehicles covers a wide range, such as safe driving, safe reversing, and safe navigation, all of which belong to the category of safe driving of vehicles. [0003] At present, reversing radar and reversing image are usually used to ensure the safety of reversing the car. In addition, in order to solve the problem of navigation safety, the head-up display (HUD) has also been gradually applied to the automotive field in recent years to replace the two-dimensional navigation screen on the center console. To reduce traffic safety accidents caused by the driver looking down at the car navigation, and for the safe driving of the car, especially in heavy fog, rain and snow, how to ...

[0003] At present, reversing radar and reversing images are usually used to ensure the safety of reversing cars. In addition, in order to solve the problem of navigation safety, head-up display (HUD) has also been gradually applied to the automotive field in recent years to replace the two-dimensional navigation screen on the center console. To reduce traffic safety accidents caused by the driver looking down at the car navigation, and for the safe driving of the car, especially in heavy fog, rain and snow, how to guide the driving on the road marking lines and the distance of the vehicle ahead during dynamic driving driver's safe driving, there is still no good solution
