Abstract
A dynamic graphic information classification device which is installed in a vehicle and comprises at least one automatic driving assistant system, a wireless communication interface, a storage device, a GPS module, and a processor. The wireless communication interface is connected with a cloud server where a high definition map and 3D point cloud map information are stored. The GPS module acquires position coordinates of the vehicle from an electronic map. The storage device stores at least one of at least one road curvature and at least one crossroads feature of a road environment of a predetermined driving path of the vehicle. The processor classifies the map information to be downloaded according to at least one of at least one road curvature and at least one crossroads feature and an automatic driving level of the automatic driving assistant system, whereby to reduce the time for download.
