MONITORING DEVICE, MONITORING METHOD, MONITORING PROGRAM, AND MONITORING SYSTEM
A monitoring system includes a mobile terminal, and a management device which communicates with the mobile terminal, in which the mobile terminal includes a first transmission unit which transmits position information of the mobile terminal to the management device at a predetermined interval, and the management device includes a control unit which controls, when acquiring the position information, a direction of a camera based on the position information. A monitoring system may include a mobile terminal and a management device which communicates with the mobile terminal, in which the mobile terminal includes a first transmission unit which transmits position information of the mobile terminal to the management device, and the management device includes a control unit which controls, when acquiring the position information, a direction of a camera based on the position information, a tracking unit which extracts a tracking target candidate based on an image acquired from the camera, and a display unit which displays the image and highlights the tracking target candidate included in the image so as to be selectable.
1 . A monitoring system comprising:
a mobile terminal; and
a management device configured to communicate with the mobile terminal, wherein
the mobile terminal includes a first transmission unit implemented at least by a hardware including a processor and configured to transmit position information of the mobile terminal to the management device at a predetermined interval, and
the management device includes a control unit implemented at least by the hardware and configured to control, when acquiring the position information, a direction of a camera based on the position information.
2 . The monitoring system according to claim 1 , wherein the control unit controls the direction of the camera to a position indicated by the position information.
3 . The monitoring system according to claim 1 , wherein
the mobile terminal includes a second transmission unit implemented at least by the hardware and configured to transmit, to the management device, control switching information for switching control of the camera when detecting a predetermined action, and
the control unit controls, when receiving the control switching information, the direction of the camera based on the position information of the mobile terminal.
4 . The monitoring system according to claim 3 , wherein
the management device has a normal mode for monitoring a predetermined range and a tracking mode for performing monitoring based on the position information, and
the control unit switches, when receiving the control switching information, the normal mode to the tracking mode and controls the direction of the camera based on the position information of the mobile terminal.
5 . The monitoring system according to claim 1 , wherein
the control unit acquires position information of each camera, and
the control unit selects at least one camera to be controlled from the camera based on the acquired position information of the camera and the acquired position information of the mobile terminal.
6 . The monitoring system according to claim 1 , wherein
the management device includes:
a tracking unit implemented at least by the hardware and configured to extract one or more tracking target candidates based a image/images acquired from the camera; and
a display unit implemented at least by the hardware and configured to display the image/images and highlight the tracking target candidates included in the image so as to be selectable.
7 . The monitoring system according to claim 6 , wherein the tracking unit determines the selected candidate as a tracking target and tracks the tracking target.
8 . The monitoring system according to claim 6 , wherein the tracking unit identifies a holder of the mobile terminal based on the image/images acquired from the camera, determines the identified holder as a provisional tracking target, and tracks the provisional tracking target.
9 . The monitoring system according to claim 6 , wherein
the tracking unit further extracts a moving object different from the holder of the mobile terminal based on the image/images acquired from the camera, and
the display unit highlights the extracted moving object as the tracking target candidate.
10 . The monitoring system according to claim 1 , wherein when detecting the predetermined action, the mobile terminal shortens an interval for acquiring the position information as compared with a case in which the predetermined action is not detected.
11 . The monitoring system according to claim 7 , wherein when the tracking unit determines the tracking target, the management device changes an interval at which the management device acquires the position information to an acquisition interval for the case in which the predetermined action is not detected.
12 . The monitoring system according to claim 2 , wherein when accepting an input to the mobile terminal, the first transmission unit transmits the position information of the mobile terminal to the management device at the predetermined interval.
13 . The monitoring system according to claim 2 , wherein
the mobile terminal further includes an acceleration sensor, and
the first transmission unit transmits the position information of the mobile terminal to the management device at the predetermined interval when acceleration acquired by the acceleration sensor is equal to or greater than a predetermined value.

18 . A management device comprising:
an acquisition unit implemented at least by a hardware including a processor and configured to acquire position information of a mobile terminal at a predetermined interval; and
a control unit implemented at least by the hardware and configured to control, when acquiring the position information of the mobile terminal, a direction of a camera based on the position information.
19 . The management device according to claim 18 , wherein the control unit controls the direction of the camera based on the position information of the mobile terminal when receiving control switching information for switching camera control from the mobile terminal.
20 . A monitoring method comprising:
acquiring position information of a mobile terminal at a predetermined interval; and
controlling, when the position information is acquired, a direction of a camera based on the position information.
