Indoor live-action navigation method and system

The invention discloses an indoor live-action navigation method and system. The method comprises the steps that a mobile terminal collects live-action images of the current position, the live-action images are matched with a first live-action image stored in an indoor live-action image database, and an initial coordinate of the current position is obtained; the position of a pedestrian is positioned and tracked in real time through a multi-source sensor fused position algorithm, and when the mobile terminal detects that the position of a user changes, a real-time position result and a walking trajectory are output; a second live-action image, closest to the indoor position result, in the indoor live-action image database is obtained according to the real-time indoor position result; the mobile terminal obtains a starting point and an ending point which are input by the user in the navigation process, a forward direction is obtained, a direction guided arrow is added on the second live-action image, and live-action navigation is conducted. By means of the indoor live-action navigation method and system, according to the position where the pedestrian is located, the live-action navigation images can be pushed automatically, the best navigation image visual angle can be judged automatically, and route guidance information such as the arrow is overlapped on the navigation images.
