The invention relates to a BIM (
building information modeling) based VR (
virtual reality) navigation method, a
server, a terminal and a
system. The method comprises the following steps: the
server acquires positional information sent by the terminal; a BIM three-dimensional
city model corresponding to the current position of the terminal and a
database are determined according to the positional information; a real scene picture sent by the terminal is acquired; a reference picture matched with the real scene picture is determined from the
database; navigation information corresponding to the reference picture is sent to the terminal and played. In a navigation process, if the terminal cannot acquire the accurate positional information, the
server still can acquire the real scene picture, shot by the terminal, of a travel
route, whether a user travels on the planned travel
route is determined by matching the reference picture in the
database, and navigation precision is guaranteed; further, the user's terminal in the embodiment of the invention can display a BIM based three-dimensional city image in real time, more realistic virtual display navigation experience is provided for a user, the user is prevented from entering a wrong way, and the navigation precision is guaranteed.
