  • Patent number: 10169914
    Abstract: 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.
