Abstract
A method and a device for performing automated calibration are described. In an example, sensorial data gathered for a space to be mapped in an indoor area is obtained from one or more data recording devices. From the sensorial data, a plurality of trajectories are derived which indicate movement of the one or more data recording devices in the space. Based on the plurality of trajectories, a structural map representing a plurality of map constraints of the space is created. Further, from the sensorial data, calibration information associated with a series of locations in the space is extracted and used along with the structural map to generate a fingerprint map of the space.

A server computing device comprising:
- a processor;
- and
- a memory storing a set of instructions, the instructions executable in the processor to:
- obtain, from one or more data recording devices, sensorial data gathered for a space to be mapped in an indoor area;
- derive a plurality of trajectories from the sensorial data, the plurality of trajectories indicating movement of the one or more data recording devices in the space;
- create, based on the plurality of trajectories, a structural map representing a plurality of map constraints of the space;
- extract, from the sensorial data, calibration information associated with a series of locations in the space;
- and
- generate, based on the calibration information and the structural map, a fingerprint map of the space for localization inside the space.
