    • 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 include: 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 the space, configured to obtain relative coordinates of the 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 the positioning device in the space based on the relative coordinates, so as to calibrate the positioning device. The positioning device can be calibrated automatically, fast and accurately using the system.
    • 本发明的实施例不仅提供了用于校准定位装置的技术方案,而且提供了用于表征空间中的感兴趣区域的技术方案。 具体地,提供了一种系统,其可以包括:能够发射测距信号的标签,放置在被选择为空间中的空间特征点的位置点处; 空间中的定位装置,被配置为基于来自所述标签的所述测距信号获得所述空间特征点相对于所述定位装置的相对坐标; 以及服务器,被配置为基于所述相对坐标确定所述定位装置在所述空间中的位置参数,以便校准所述定位装置。 可以使用系统自动,快速,准确地校准定位装置。
