Imaging system, imaging method, and not-transitory recording medium

1. An imaging system that images an object being movable, the imaging system comprising:

a transmitter that is attached to the object and wirelessly transmits a positioning signal;

a positioning device that receives the positioning signal and determines a position of the object based on the positioning signal;

an imaging device that images the object in a variable direction and at a variable magnification; and

a control device that controls the variable direction and the variable magnification of the imaging device, wherein

the control device calculates a direction and a distance from the imaging device to the object based on the position of the object, the position being determined by the positioning device,

the control device sets a first direction and a first magnification on the imaging device based on the direction and the distance that have been calculated, and

the control device sets a second direction and a second magnification on the imaging device based on imaging data generated by imaging the object, the imaging data being generated by the imaging device on which the first direction and the first magnification are set.

2. The imaging system according to claim 1 , wherein the control device sets the first direction and the first magnification in such a manner that the object is located in a scan range in an imaging range of the imaging device, the scan range being predetermined, and that the object is imaged in a first size.

3. The imaging system according to claim 2 , wherein

the object is a human being,

the control device analyzes the imaging data to recognize a body or a face of the object, and

the control device sets the second direction and the second magnification in such a manner that a center of the body or the face of the object is located in a center of the imaging range of the imaging device and that the body or the face of the object is imaged in a second size.

4. The imaging system according to claim 3 , wherein when the control device analyzes the imaging data to detect a plurality of bodies or a plurality of faces, the control device selects the body or the face of the object based on the position of the object, the position being determined by the positioning device.

5. The imaging system according to claim 3 , wherein when the body or the face of the object is not recognized by analyzing part of the imaging data, the part corresponding to the scan range, the control device enlarges the scan range and analyses part of the imaging data, the part corresponding to the scan range that has been enlarged, to recognize the body or the face of the object.

6. The imaging system according to any one of claim 1 , wherein the positioning signal includes an identifier associated with the object.

7. An imaging method for imaging an object being movable, the imaging method comprising:

wirelessly transmitting a positional signal, the wirelessly transmitting being performed by a transmitter attached to the object;

receiving the positioning signal and determining a position of the object based on the positioning signal, the receiving being performed by a plurality of receivers disposed at predetermined positions;

calculating a direction and a distance from an imaging device to the object based on the position that has been determined, of the object;

setting a first direction and a first magnification on the imaging device based on the direction and the distance that have been calculated;

imaging the object to generate imaging data, the imaging data being generated by the imaging device on which the first direction and the first magnification are set; and

setting a second direction and a second magnification on the imaging device based on the imaging data.

8. A non-transitory recording medium storing a program for controlling an imaging system that images an object being movable, the imaging system including:

a transmitter that is attached to the object and wirelessly transmits a positioning signal;

a positioning device that receives the positioning signal and determines a position of the object based on the positioning signal; and

an imaging device that images the object in a variable direction and at a variable magnification,

the program comprising steps of:

calculating a direction and a distance from the imaging device to the object based on the position of the object, the position being determined by the positioning device;

setting a first direction and a first magnification on the imaging device based on the direction and the distance that have been calculated; and

setting a second direction and a second magnification on the imaging device based on imaging data generated by imaging the object, the imaging data being generated by the imaging device on which the first direction and the first magnification are set.
