Abstract
Provided are a spatial sensing device, and the like, that are suitable for spatial sensing. This spatial sensing device (3) comprises a sensing data acquisition means (11) for acquiring sensing data through optical fiber sensing using a plurality of optical fiber cables (1) laid in different directions and an object detection means (12) for using the sensing data to detect the position of an object in a space of interest.
Claims24
A spatial sensing device comprising:
- at least one memory configured to store instructions;
- and
- at least one processor configured to execute the instructions to:
- acquire sensing data based on optical fiber sensing using a first optical fiber cable laid in a first direction departing from a land surface or approaching the land surface and second optical fiber cable laid in a second direction that is not parallel to the first direction;
- and
- detect a location of an object in a target space by using the sensing data,
- wherein the location includes a first coordinate value corresponding to the first direction.
