An intelligent disaster prevention system and an intelligent disaster prevention method are provided. The intelligent disaster prevention system includes a server and an electronic device coupled to the server. The server detects the electronic device in a disaster area and obtains a location information of the electronic device. The server obtains real-time disaster information from a website. The server obtains a real-time aerial image corresponding to the disaster area. The server selects a first refuge from a plurality of refuges corresponding to the disaster area according to the location information, the real-time disaster information, and the real-time aerial image, and calculates an evacuation route from the location information to the first refuge. The electronic device receives the first refuge and the evacuation route, and displays the first refuge and the evacuation route on a map.

Intelligent disaster prevention system and intelligent disaster prevention method

A distributed indoor positioning system and a method thereof are disclosed. In the method, indoor map data corresponding to a place where a user is located is loaded first, and an indoor image of the place where the user is located is captured to generate an image stream. Next, the image stream is compressed to reduce dimensionality thereof, so as to generate a dimensionality-reduced image. The indoor map data corresponding to the dimensionality-reduced image is obtained from the loaded indoor map data, and a position of the user is determined according to the obtained indoor map data.

Distributed indoor positioning system and method thereof

A positioning system and a positioning method based on magnetic field intensity are provided. The positioning method includes: storing a magnetic fingerprint of a first place; sensing, by a mobile terminal, a magnetic field of the first place to generate sensed data; determining whether the mobile terminal is located inside or outside a vehicle according to the sensed data and the magnetic fingerprint; determining that the mobile terminal is located at a first location of the first place according to the sensed data and the magnetic fingerprint.

Positioning system and positioning method based on magnetic field intensity

Provided are an indoor positioning system and method based on geomagnetic signals in combination with computer vision, including: a computer vision positioning module for acquiring a spatial image of a surrounding environment to create computer vision coordinates; a geomagnetic signal positioning module for detecting trajectories of the geomagnetic signals for creating geomagnetic signal coordinates; a map generating module including a database for storing the created computer vision coordinates and the created geomagnetic signal coordinates, and an inertial measurement unit for detecting a current position and a traveling trajectory, to generate a computer vision map and a geomagnetic data map; and a weighting module for calculating a computer vision weight and a geomagnetic signal weight based on the created computer vision coordinates and the created geomagnetic signal coordinates, and inputting the computer vision weight and the geomagnetic signal weight in a weight equation to estimate a present location.

Indoor positioning system and method based on geomagnetic signals in combination with computer vision

An indoor positioning method, indoor positioning system and indoor maps creating device thereof are provided. The method includes converting a panorama image corresponding to an indoor environment into a plurality of perspective images, and extracting a plurality of reference feature points and descriptors of the reference feature points from the perspective images; taking a shooting position of the panorama image as an origin, and recoding a plurality of 3D reference coordinate values corresponding to a central position of each perspective images; calculating 3D coordinate values of the reference feature points base on the 3D reference coordinate values, and storing the 3D coordinate values and the descriptors of the reference feature points as an indoor map corresponding to the indoor environment. The method also includes determining a 3D target coordinate value of a portable electronic device with respect to the origin of the indoor maps in the indoor environment.
