Abstract
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.
