At present, the number of motor vehicles, including household and commercial vehicles, continues unabated. However, the rate of road traffic accidents increases accordingly. In addition to the driver's driving skills and habits, the vehicle itself has a great impact on the driver. Visual constraints are also an important factor. Although the driver can observe the surrounding environment through the windshield, rearview mirror, etc. during driving, almost all motor vehicles have visual blind spots, especially those large commercial vehicles, which have a larger body and a larger visual blind spot. , the driver cannot have a comprehensive and clear understanding and grasp of the surrounding environment of the vehicle, and scratches, collisions and injury accidents often occur in the process of starting, driving, turning, changing lanes or reversing the vehicle. In order to reduce the occurrence of accidents, conventional radars, cameras and other devices are also used in the prior art to monitor distance between vehicles and reversing images. , Comprehensive and intuitive images of the vehicle and surrounding environment, allowing the driver to have a comprehensive understanding of the vehicle itself and the surrounding environment, including roads, vehicles, pedestrians, etc. , improve driving safety and reduce accidents.

On the other hand, although the car navigation map has been very common, it is only possible to see the geographic location of the vehicle and the simple, fixed road facilities and traffic information preset in the map from the navigation map. During long-distance driving, it can obtain real-time environmental images such as mountains, rivers, buildings, vehicles, pedestrians, etc. around the vehicle, and display these images on the navigation map in real time, which will help drivers improve driving safety and at the same time extremely Greatly improve driving pleasure.
