Terminal apparatus and operation method of terminal apparatus

A terminal apparatus comprising:

• an input unit;
• and
• a controller configured to accept, via the input unit, an input of setting any point for at least one selected from the group consisting of a first region, a second region, and a third region,
• the first region corresponding to both an observation region of a first sensor and an observation region of a second sensor,
• the second region corresponding to the observation region of the first sensor and not overlapping the first region,
• the third region corresponding to the observation region of the second sensor and not overlapping the first region,
• wherein information on a position of a predetermined point in the observation region of the first sensor or the observation region of the second sensor is acquired based on the any point,
• the controller is configured to accept, via the input unit, a first input as the input of setting the any point, the first input indicating which of a first coordinate system, a second coordinate system, and a third coordinate system is to be set or corrected using the any point,
• the first coordinate system is set with respect to the first region,
• the second coordinate system is set with respect to the second region, and
• the third coordinate system is set with respect to the third region.

An operation method of a terminal apparatus, comprising:

• accepting an input of a calibration point for calibrating a first coordinate space corresponding to a first region in real space detected by a first sensor and a second coordinate space corresponding to a second region in real space detected by a second sensor, the calibration point disposed in an overlapping region in which a first observation region of the first sensor and a second observation region of the second sensor overlap;
• determining a position of the calibration point in real space;
• and
• calibrating a first coordinate system of the first sensor based on the position of the calibration point in real space and a position of the calibration point in the first region and a second coordinate system of the second sensor based on the position of the calibration point in real space and a position of the calibration point in the second region,
• wherein information on a position of an object in the first observation region of the first sensor or the second observation region of the second sensor is acquired based on a position of the object in real space.
