Abstract: A full-vision navigation and positioning method for a smart terminal is proposed. The smart terminal turns on a 3D full visual navigation and performs a network speed test. When a network speed is higher than or equal to a threshold value, the smart terminal turns on a camera to obtain images of a current street view and upload the images. The smart terminal compares the images with a 3D panorama map to feedback a current position and utilizes a 3D navigation system to continue navigation according to the current position.
