Imaging system, angle-of-view adjustment method, and angle-of-view adjustment program

A method for adjusting an angle of view of an imaging unit that is provided in a moving body and is capable of performing at least one of a pan operation or a tilt operation, the method comprising:

• a captured data transmission step of transmitting captured data obtained by an imaging operation of the imaging unit;
• a captured data receiving step of receiving the captured data transmitted in the captured data transmission step;
• an imaging operation step of transmitting an imaging control signal for operating the imaging unit to the imaging unit, using communication;
• a display step of displaying a captured image indicated by the captured data received in the captured data receiving step on a display screen;
• a coordinate designation step of designating designation coordinates which are coordinates of a movement target and movement destination coordinates which are coordinates of a movement destination of the movement target in the image displayed on the display screen in a case in which the angle of view of the imaging unit is adjusted;
• an angle-of-view adjustment operation step of calculating pan/tilt operation parameters, using the designation coordinates and the movement destination coordinates;
• an angle-of-view adjustment period calculation step of calculating an angle-of-view adjustment period which is a period from the designation of the designation coordinates to the adjustment of the angle of view of the imaging unit;
• a movement state calculation step of calculating motion parameters indicating a moving direction and a movement distance in a case in which the imaging unit is moved by the movement of the moving body for the angle-of-view adjustment period from the captured data obtained by the imaging operation of the imaging unit;
• a pan/tilt operation parameter correction step of correcting the pan/tilt operation parameters calculated in the angle-of-view adjustment operation step on the basis of the motion parameters calculated in the movement state calculation step and the angle-of-view adjustment period calculated in the angle-of-view adjustment period calculation step in a case in which the angle of view of the imaging unit is adjusted;
• and
• a pan/tilt operation command step of instructing the imaging unit to perform at least one of the pan operation or the tilt operation on the basis of the pan/tilt operation parameters corrected in the pan/tilt operation parameter correction step.

A computer-readable non-transitory tangible medium storing an angle-of-view adjustment program that causes a computer to function as:

• imaging means provided in a moving body;
• captured data transmission means for transmitting captured data obtained by an imaging operation of the imaging means;
• captured data receiving means for receiving the captured data transmitted from the captured data transmission means;
• pan/tilt operation means for instructing the imaging means to perform at least one of a pan operation or a tilt operation;
• imaging operation means that is connected to the imaging means so as to communicate with the imaging means and transmits an imaging control signal for operating the imaging means to the imaging means;
• display means for displaying a captured image indicated by the captured data received by the captured data receiving means on a display screen;
• coordinate designation means for designating designation coordinates which are coordinates of a movement target and movement destination coordinates which are coordinates of a movement destination of the movement target in the image displayed on the display screen of the display means in a case in which an angle of view of the imaging means is adjusted;
• angle-of-view adjustment operation means for calculating pan/tilt operation parameters applied to the pan/tilt operation means, using the designation coordinates and the movement destination coordinates;
• angle-of-view adjustment period calculation means for calculating an angle-of-view adjustment period which is a period from the designation of the designation coordinates to the adjustment of the angle of view of the imaging means;
• movement state calculation means for calculating motion parameters indicating a moving direction and a movement distance in a case in which the imaging means is moved by the movement of the moving body for the angle-of-view adjustment period from the captured data obtained by the imaging operation of the imaging means;
• pan/tilt operation parameter correction means for correcting the pan/tilt operation parameters calculated by the angle-of-view adjustment operation means on the basis of the motion parameters calculated by the movement state calculation means and the angle-of-view adjustment period calculated by the angle-of-view adjustment period calculation means in a case in which the angle of view of the imaging means is adjusted;
• and
• pan/tilt operation command means for transmitting a signal corresponding to the pan/tilt operation parameters to the pan/tilt operation means, using communication, and transmitting a signal corresponding to the pan/tilt operation parameters corrected by the pan/tilt operation parameter correction means to the pan/tilt operation means.
