Abstract

The invention discloses an autonomous navigation system based on an indoor planar graph. The system comprises a map translation module and a navigation module. Intelligent terminals such as a mobile phone and a tablet personal computer are used for taking pictures of an indoor map, and related physical information such as scales and directions in the map is calculated. The map translation module is used for extracting a road and planning paths. The navigation module is used for associating user information with the paths according to the planned paths and guiding a user to reach a destination. Without collecting the information or deploying an infrastructure in advance, the information in the existing indoor map is sufficiently dug by the aid of the indoor map existing extensively in life, and end-to-end accurate indoor navigation services are provided by the aid of mobile phone sensors of the intelligent terminals.

Description

technical field [0001] The invention relates to the technical field of indoor navigation, in particular to an autonomous navigation system based on an indoor floor plan. Background technique [0002] With the continuous improvement of urban modernization, the number of large buildings is increasing, and the physical layout of indoor spaces is becoming more and more complex. Therefore, the demand for indoor navigation services has grown significantly. Outdoor navigation has long been widely used in daily life, but the indoor environment is complex and changeable, and the traditional outdoor navigation mode cannot be applied to the indoor environment. Therefore, indoor navigation is still in the research stage, and there is no widely used indoor navigation system. [0003] At present, most of the existing indoor navigation systems build indoor maps based on indoor positioning. However, these methods for indoor navigation require pre-deployment of infrastructure (e.g., WSNs,...
