Technical Field

[0002] GPS (Global Positioning System) is the current mainstream positioning technology. It is a navigation system that combines satellite and wireless technologies to provide users with accurate positioning. Users can easily use GPS to obtain positioning information in areas where satellite signals can be received. However, in indoor environments, GPS signals may not be received well due to obstruction by buildings, so GPS cannot be used for positioning, and indoor positioning systems are derived from this. Using indoor positioning technology as an auxiliary positioning for satellite positioning can solve the problem that satellite signals are weak when they reach the ground and cannot penetrate buildings, and ultimately locate the current location of the object.

[0036] See also Figure 2, is a schematic diagram of the structure of the positioning system of the present invention, the positioning system comprises:

[0037] An image acquisition device 10 is used to acquire data of a real space where a target location is located, so as to obtain image features of the target location;

[0038] Positioning acquisition device 20, used to acquire the position information coordinates of the target location in the real space;

[0039] A positioning device 30, wherein the positioning device 30 comprises:

[0040] A modeling device 31, connected to the image acquisition device 10, for receiving the data of the real space and establishing a corresponding virtual space model according to the data of the real space;

[0041] A processing device 32, connected to the positioning acquisition device 20 and the modeling device 31, for converting the position information coordinates of the target point in the real space into the position information coordinates of the virtual space model in the modeling device 31;

[0042] The display device 33 is used to display the location of the target location.

[0043] The image acquisition device 10 is a camera, which is used to collect data of the real space in the room where the target location is located.

[0044] The modeling device 31 establishes a corresponding 3D virtual space model according to the data of the real space in a required proportion.

[0045] The modeling device 31 generates virtual space data according to the real space data in a required proportion. The real space data corresponds to the virtual space data and is synchronized in real time. Then, a corresponding 3D virtual space model is established according to the virtual space data.

[0046] Among them, the positioning acquisition device 20 is a Bluetooth base station, which is installed indoors. The Bluetooth base station is deployed according to the positioning principle of the triangle centroid method, with the maximum distance covered by the Bluetooth base station signal as the unit, and the current position information coordinates of the target location in the real space are obtained according to the signal strength.

[0047] like Figure 3The figure shows a schematic diagram of the triangular centroid method for positioning a Bluetooth base station. The three circles (circle A, circle B, circle C) formed by the signal ranges of three adjacent base stations have three intersection points (P1, P2, P3), forming a triangular area (△P1P2P3). The location of the mobile node, i.e., the target location, is within the common intersection area of ​​the three circles (shown in the shaded area). The centroid of the triangle is taken as the estimated location of the mobile node. The signal coverage ranges of the three base stations are known, i.e., the coordinates of the center of the three circles (circle A, circle B, circle C) and the radius are known. The equations of the three circles can be combined to obtain the coordinates of the three intersection points (P1, P2, P3), and then the location coordinates of the mobile node, i.e., the target location, can be obtained through the triangle centroid relationship. The Bluetooth base stations deployed indoors are managed by a specific positioning server.

[0048] The processing device 32 includes a map engine, through which the location information coordinates of the target location in the real space are converted into location information coordinates of the virtual space model in the modeling device 31 .

The modeling device 31 in the mobile phone end establishes a corresponding 3D virtual space model according to the acquired spatial data according to the required appropriate proportion, and displays it through the mobile phone display screen. The position information coordinates of the target location in the real space obtained by the indoor Bluetooth base station are transmitted to the mobile phone end, and the map engine in the processing device 32 in the mobile phone end converts the position information coordinates of the target location in the real space into the position information coordinates of the 3D virtual space model in the modeling device 31. Finally, the location of the target location realizes a three-dimensional virtual display of the real space through the mobile phone display screen.
