1. A monitoring control device comprising:
at least one memory storing instructions, and
at least one processor configured to execute the instructions to:
acquire measurement data indicating a sensing region of a plurality of distance measurement sensors provided to monitor a monitoring target facility, the plurality of distance measurement sensors perform sensing in a local coordinate system and by sweeping an optical signal;
convert the sensing region from the local coordinate system to a global coordinate system of map data indicating the monitoring target facility, by referring to position data of the plurality of distance measurement sensors;
discriminate a position that cannot be sensed and a position that can be sensed in the map data, from information relating to the plurality of distance measurement sensors and information relating to a fixed object placed in the monitoring target facility; and
identify a non-monitoring region in the map data, based on the sensing region and position data of the plurality of distance measurement sensors, when the sensing region indicated by the measurement data is smaller than the sensing region in a normal state associated with the map data.
