METHOD, DEVICE AND SYSTEM FOR CALIBRATING POSITIONING DEVICE
First Claim
1. A system comprising:
- a tag capable of emitting ranging signals, placed at at least two area of interest (AOI) feature points which can characterize an area of interest in a space;
a positioning device in said space, configured to obtain location parameters of said AOI feature points based on the ranging signals from the tag; and
a server, configured to characterize said area of interest based on the location parameters of said AOI feature points.

Abstract
Embodiments of the present invention provide not only a technical solution for calibrating a positioning device but also a technical solution for characterizing an area of interest in a space. Specifically, there is provided a system, which may comprise: a tag capable of emitting ranging signals, placed at location points which are selected as space feature points in the space; a positioning device in said space, configured to obtain relative coordinates of said space feature points in relation to the positioning device based on the ranging signals from the tag; and a server, configured to determine location parameters of said positioning device in said space based on said relative coordinates, so as to calibrate said positioning device. The positioning device can be calibrated automatically, fast and accurately using the system.
