  "textContent": "A visual vehicle-positioning fusion system and a method thereof is provided. In the method, an image point cloud map stored in a storage device is converted into a longitude and latitude database corresponding to the image point cloud map. Longitude and latitude measurement coordinates received by a positioning device are used as first location information. The longitude and latitude database is compared with the longitude and latitude measurement coordinates to generate the initial location of a vehicle. Feature matching is performed on the initial location and the image point cloud map to generate second location information of the vehicle on the image point cloud map. The first location information or the second location information is selected as a final positioning output information and outputted based on a positioning fusion rule.",
