[0025] In the past two years, as the Chinese government has vigorously encouraged the development of high-tech industries, augmented reality (AR) technology has become known to most people. Now, with the continuous breakthroughs in technology, AR glasses will gradually be applied to future industrial fields. However, in the automotive field, AR still has a lot of room for development, and no company on the market has applied AR glasses to vehicles. On the one hand, in-vehicle AR applications can provide drivers with better traffic environment information prompts; on the other hand, in the in-vehicle environment, through the connection with the in-vehicle communication terminal, it can bring more entertainment driving experience to non-drivers. Figure 1 is a structural diagram of an in-vehicle perception system based on AR glasses provided in an embodiment of the present invention, see Figure 1The main function of the present invention is that in a vehicle-mounted environment, the driver can wear AR glasses to increase the recognition of pedestrians, vehicles and road test information in the surrounding environment, and obtain road condition information to the AR glasses. The AR glasses communicate with the vehicle-mounted communication terminal to send the corresponding traffic information to the vehicle end, and integrate it with the information of the vehicle-mounted communication terminal. The identified identification content matching location information can be sent to the vehicle-mounted communication terminal VBOX, converted into V2X information, sent to the cloud background and broadcast to other vehicles, further increasing the safety and reliability of vehicle driving.
[0026] Figure 2 is a schematic diagram of the structure of another vehicle-mounted perception system based on AR glasses provided in an embodiment of the present invention. This embodiment can be applied to the situation where AR glasses are used to perceive and obtain the current vehicle roadside information, such as Figure 2 As shown, the vehicle-mounted perception system based on AR glasses provided in an embodiment of the present invention may include: an object recognition module 210, an information acquisition module 220, a data fusion processing module 230 and an information transmission module 240; wherein:
