Abstract

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.

Description

technical field [0001] The invention relates to the technical field of indoor positioning, in particular to an indoor real-scene navigation method and system. Background technique [0002] With the development of smart mobile terminals and wireless network technologies, more and more people use smart phones for positioning and navigation. Faced with a wide range of pedestrian navigation needs, mobile terminal pedestrian navigation applications have received extensive attention from the mobile phone industry and location-based services, and have become one of the key applications in the mobile phone industry. [0003] Pedestrian navigation refers to the technology and method of using electronic maps, live images and other guiding information to help pedestrians reach their destinations on the basis of real-time positioning. The current pedestrian navigation system still mainly stays in the path planning and path guidance using the flat map. According to the starting point an...
