(Function)
FIG. 4 is a flowchart showing a basic detection flow of the detection system according to the present embodiment.

  First, when there is no position information of the target area in the storage unit 230 of the information processing device 200 (NO in step S101), the sensor movement transmission unit 260 of the information processing device 200 moves the image sensor 100 to a certain point (step S102). ). Then, the moving unit 150 of the image sensor 100 moves and stops the image sensor 100 (step S103). Then, the imaging unit 110 of the image sensor 100 acquires the image data of the target area, and the image transmission unit 130 transmits the image data to the information processing apparatus 200 via the communication unit 140 (step S104).

  Then, the receiving unit 220 of the information processing apparatus 200 acquires image data via the communication unit 210 (step S105). In the image processing unit 240 of the information processing apparatus 200, the position information processing unit 242 processes position information from the acquired image data (step S106). For example, the location where the image sensor 100 is located is identified from the shape of easily identifiable furniture, the shape of the cage of the poultry farm, the angle of the figurine used as a landmark, etc., and stored in the storage unit 230.

  Thereafter, the process returns to step S101, and if there is a place where position information is not yet stored in the target area, the image sensor 100 is moved to that point and the position information is similarly processed. Steps S101 to S106 are repeated until the position information of all target areas is stored in the storage unit 230 of the information processing device 200.

  After the position information of all target areas is stored in the storage unit 230 of the information processing device 200 (YES in step S101), the sensor movement transmission unit 260 of the information processing device 200 moves the image sensor 100 to a certain point. (Step S107). Then, the moving unit 150 of the image sensor 100 moves and stops the image sensor 100 (step S108). Then, the imaging unit 110 of the image sensor 100 acquires image data of the target area, and the image transmission unit 130 transmits the image data to the information processing device 200 via the communication unit 140 (step S109).

  Then, the receiving unit 220 of the information processing apparatus 200 acquires image data via the communication unit 210 (step S110). In the image processing unit 240 of the information processing apparatus 200, the position information processing unit 242 processes position information from the acquired image data (step S111). For example, among image data to be acquired, the image sensor 100 is compared with the position information stored in the storage unit 230 based on the shape of easy-to-determine furniture, the shape of the cage of the poultry farm, the angle of the figurine used as a landmark, and the like. Specify the position of. Alternatively, the position of the image sensor 100 is specified by recognizing characters included in the acquired image data.

  Thereafter, the difference information processing unit 241 in the image processing unit 240 of the information processing device 200 determines whether there is a difference in the acquired image data (step S112). If the image data to be acquired in the target area has changed within a certain time (YES in step S113), the sensor movement transmission unit 260 of the information processing apparatus 200 moves the image sensor 100 to the next certain point (step S107).

  On the other hand, if there is no change within a certain time for the image data to be acquired in the target area (NO in step S113), the output unit 270 of the information processing apparatus 200 outputs a warning (step S114). The warning output is, for example, display, alarm notification, or data output to another device.

  FIG. 5 is a flowchart showing a detection flow of the detection system including the speaker 300 according to the present embodiment. FIG. 5 differs from FIG. 4 in that steps S201 to S207 are added. Since these points are the same as those in the second embodiment, the same portions are denoted by the same reference numerals and detailed description thereof is omitted. Description is omitted.

  Similar to the image sensor 100, the speaker 300 is movable or disposed in a target area. For example, consider the case of use in a poultry farm.

  When the difference information processing unit 241 of the image processing unit 240 of the information processing device 200 determines that there is no change within a certain time with respect to the image data acquired in the target area (NO in step S113), the information processing device The 200 alert transmission unit 250 alerts the speaker 300 (step S201). Then, the speaker 300 issues a report (step S202). For example, when the target area is a chicken farm, if there is no difference in the position of the chicken from the first acquired image, the speaker 300 is issued to determine whether the chicken is sleeping or dead.

  Thereafter, the information processing apparatus 200 causes the image sensor 100 to capture an image (step S203). Then, the imaging unit 110 of the image sensor 100 acquires the image data of the target area, and the image transmission unit 130 transmits the image data to the information processing apparatus 200 via the communication unit 140 (step S204).

  Then, the receiving unit 220 of the information processing apparatus 200 acquires image data via the communication unit 210 (step S205). Next, the difference information processing unit 241 of the image processing unit 240 of the information processing device 200 then differs between the image data acquired in step S110 and the image data acquired in step S205 after the speaker 300 is issued. It is determined whether there is any (step S206). If there is a difference (YES in step S207), the sensor movement transmitter 260 of the information processing device 200 moves the image sensor 100 to the next certain point (step S107).

  That is, for example, in the case of a chicken farm, the chicken is alive because the chicken is in the same position in the image acquired in step S110 and the image acquired in step S110, but in the image acquired in step S205. I understand. Therefore, no warning is issued and another area is detected.

  On the other hand, when there is no difference (NO in step S207), the output unit 270 of the information processing device 200 outputs a warning (step S114). In other words, in the case of a chicken farm, the chicken is located in the same place in the image obtained first and the image obtained in step S110, and the chicken is located in the same place in the image obtained in step S205 after the report. Is likely dead. Therefore, the information processing apparatus 200 outputs a warning and informs the administrator of the position of the chicken.

(effect)
In the detection system 400 configured as described above, living body detection with a wide detection range can be performed by using the movable image sensor 100 and comparing image data obtained by imaging a predetermined position at regular intervals. .

  Note that the function of the image processing unit 240 according to the present embodiment may be in the information processing apparatus 200 as in the present embodiment, or may be in the image sensor 100. Alternatively, the image sensor 100 may be in another device that is communicably connected. At that time, the image sensor 100 does not transmit image data to be acquired, but transmits data after processing the image.

  Moreover, when specifying the position of the movable image sensor of this embodiment, you may specify from the image data to acquire, and you may specify by GPS, an ultrasonic sensor, an optical sensor, and an acceleration sensor.

  Further, by installing a thermographic sensor or a biosensor together with the movable image sensor 100 of the detection system 400 according to the present embodiment and moving the sensor in the same manner, it is possible to perform more accurate biometric detection.
