INDOOR POSITIONING SYSTEM AND METHOD BASED ON PATH SET AND COORDINATE SYSTEM
Document Type and Number:
WIPO Patent Application WO/2017/000515
Kind Code:
A1
Abstract:
An indoor positioning system and method based on a path set and a coordinate system. The positioning system comprises a data acquisition unit (10), a data processing unit (11) and a data storage unit (12). The system utilizes the data processing unit (11) to calculate position information acquired by the data acquisition unit (10), so as to obtain a current coordinate of a terminal device and record a traveling path of the terminal device. The data storage unit (12) stores a preset path set and traveling path, such that the position information of the terminal device can be recorded, and in turn, the positioning of the terminal device is achieved. The position information comprises a displacement of the terminal device relative to a start point and a rotation angle of the terminal device in a pre-established coordinate system.
