A vehicle-mounted multi-mode augmented reality system based on real road condition information three-dimensional modeling

A vehicle-mounted multi-mode augmented reality system based on real road condition information three-dimensional modeling comprises a real-time road condition information acquisition unit, a surrounding environment modeling unit, a virtual reality simulation unit, a safety prompt unit and an emergency processing unit. Wherein the real-time road condition information acquisition unit is used for acquiring road condition information, and the surrounding environment modeling unit is used for finishing three-dimensional modeling of a surrounding environment and identifying and classifying different obstacles according to the road condition information and carrying out theme replacement on the classified different obstacles; The virtual reality simulation unit is used for generating a two-dimensional image of a virtual three-dimensional environment and displaying the two-dimensional image; The safety prompt unit is used for judging whether the current road section can be switched to a virtual theme entertainment m
