|Title:||SYSTEM FOR NAVIGATING INSIDE OF BUILDING AND APPLICATION SYSTEM THEREFOR|
A system for navigating the inside of a building. The system comprises a server and a mobile client, the mobile client being connected to the server via a network, characterized in that the server comprises a file database used for storing geographical location information of a building and a three-dimensional image file for said building; the mobile client comprises: a display module responsible for displaying said three-dimensional image file; a satellite positioning module responsible for determining the location of the mobile client by means of satellite positioning; an indoor positioning module responsible for determining the location of the mobile client on the basis of changes in the acceleration of the angle and the displacement of the mobile client; and, an indoor navigation module responsible for navigating the inside of a building on the basis of the three-dimensional image file. The system can automatically analyze a DXF file and can automatically generate three-dimensional building data, thereby allowing for the creation of a cloud network-based three-dimensional image of a building, and uses mobile client satellite positioning and a sensor such as a gyroscope to achieve indoor navigation.
