Abstract

The invention discloses an indoor positioning method and system and a computer readable medium. The method comprises that an initial position of a target object is determined by means of wireless positioning and visual feature and map matching positioning; and according to the initial position of the target object, the target object is located in real time by means of short time interframe featurematching positioning and visual feature and map feature matching positioning. Via the indoor positioning method, the computational complexity of the visual feature and map matching positioning manneris reduced.

Description

Technical field [0001] The invention belongs to the technical field of indoor positioning, and specifically relates to an indoor positioning method, an indoor positioning system and a computer readable medium. Background technique [0002] With the rapid increase of data services and multimedia services, people’s demand for positioning and navigation is increasing, especially in complex indoor environments, such as buildings, airport halls, exhibition halls, supermarkets, libraries, underground parking lots, etc. It is necessary to determine the indoor location information of the mobile terminal or its holder, facilities and objects. Therefore, visual positioning technology and wireless positioning technology appeared. Based on wireless positioning methods, such as Bluetooth positioning, wifi positioning, etc., the calculation is small, and real-time positioning can be achieved on the mobile phone or tablet that the user carries, but the positioning accuracy is not high and it i...
