At least one of the processes of blinking is performed. And in the entrance / exit management system in this embodiment, each monitoring camera 200-1 to 200-3 captures an image including the ship 100. And the ID detection part 311 of the entrance / exit management apparatus 300 extracts the blink pattern of the starlight or portlight of the ship 100 from the image | video which each monitoring camera 200-1 to 200-3 image | photographed, and detects ID of the ship 100 To do.
Thereby, the introduction of the system to the ship 100 can be suppressed only by introducing a circuit for blinking the starlight or the portlight that is normally installed in the ship 100, and the introduction cost to the ship 100 can be reduced. .

The operation of the entry / exit management system will be described below.
First, the operation of the ship 100 will be described.
The lighting equipment of the ship 100 is activated when a crew member of the ship 100 depresses a lighting switch for the port lights and starboard lights. When the lighting equipment is activated, the modulation unit 102 of the ship 100 acquires the ID of the ship 100 from the ID storage unit 101. When the modulation unit 102 acquires the ID of the ship 100, the modulation unit 102 generates an ID code that is information indicating whether the starlight and the portlight are turned on or off based on the acquired ID. The ID code indicates the ID stored in the ID storage unit 101. For example, the ID code is generated by converting the ID acquired by the modulation unit 102 into a binary number, and generating an ID code indicating that the ID is turned on when “1” and turned off when “0”, or the acquired ID Is encoded into a character code such as a Morse code and an ID code indicating lighting / extinction is generated. When the modulation unit 102 generates the ID code, the modulation unit 102 outputs the generated ID code to the star lamp lighting unit 104 and the port lamp lighting unit 103. The star lamp lighting unit 104 and the port lamp lighting unit 103 blink the star lamp and the port lamp according to the input ID code. At this time, by setting the blinking speed to, for example, several hundred hertz, it looks like it is always lit with the naked eye, and blinking can be measured at the scanning speed of each of the monitoring cameras 200-1 to 200-3.
In this way, the ship 100 navigates the route while constantly outputting the ID of the ship 100 by blinking the port lights and starboard lights.

Next, the operation of the land facility will be described.
FIG. 5 is a flowchart for explaining the operation of the port entry / exit management device.
At the onshore facility, the port entry monitoring camera 200-1, the berthing monitoring camera 200-2, and the departure monitoring camera 200-3 always take images of the port and output them to the analysis unit 310 of the port entry / exit management device 300. When each monitoring camera 200-1 to 200-3 outputs the video information, the ID detection unit 311 of the analysis unit 310 detects the light emission of the port lamp from the video information. Since the port light is a red light, the detection of the port light is performed by, for example, converting the color space of the video information to YCbCr (Y: luminance, luminance, Cb: blue chrominance component, blue color difference component, Cr: red chrominance component, red color difference component ) Format, the ID detection unit 311 includes a portion (hereinafter, referred to as a red light emitting portion) where the luminance (Y) and the red color difference component (Cr) are equal to or greater than a predetermined threshold in each frame of the video information. This is done by determining whether or not it exists. When detecting the light emission of the port light, the ID detection unit 311 extracts the light emission pattern and detects the ID of the ship 100 (step S1). The ID is detected by the following process, for example. First, the ID detection unit 311 extracts a red light emission portion for each frame from the video in which the light emission of the left lamp is detected. At this time, since the ship 100 is navigating, the coordinates of the red light emitting portion in the video are different for each frame, and when the port light is OFF, the red light emitting portion cannot be extracted. Therefore, the ID detection unit 311 extracts a red light emitting portion within a predetermined range from a plurality of frames subsequent to the last frame from the coordinates of the red light emitting portion in the last frame from which the red light emitting portion is extracted. , ON / OFF of the port lights by the same ship 100 is detected. When detecting the port lamp ON / OFF, the ID detection unit 311 detects the ID code based on the blinking speed and the video frame speed. For example, when the blinking speed is 300 Hz and the frame rate of the video is 1200 fps, the ID detection unit 311 determines that “1” is indicated when the red light emitting portion of the same ship 100 is detected for four consecutive frames. The ID detection unit 311 determines that “0” is indicated when the red light emission portion of the same ship 100 cannot be detected continuously for four frames. By repeating this process, the ID code is detected. When detecting the ID code, the ID detection unit 311 decodes the detected ID code and acquires the ID of the ship 100.

  When the ID detection unit 311 detects the ID of the ship 100, the ship information acquisition unit 316 determines whether the ship information corresponding to the ID detected in the ship information storage unit 315 is stored in the ship information storage unit 315. (Step S2). When it is determined that ship information corresponding to the detected ID exists (step S2: YES), the ship information acquisition unit 316 acquires ship information of the ship 100 from the ship information storage unit 315 based on the detected ID (step S2). S3).

When the vessel information acquisition unit 316 acquires vessel information, the position specifying unit 313, based on mapping information that associates the coordinates of one point in the frame of the video stored in the mapping information storage unit 312 with the coordinates of one point on the map, The position on the map of the ship 100 and the size of the ship 100 are specified from the video in which the ID detection unit 311 detects the ID (step S4).
The calculation of the position of the ship 100 is performed by the following process, for example. First, the position specifying unit 313 extracts a pixel area indicating the ship 100 by extracting a difference between frames of a video or a color difference between a background image and a video stored in advance. When the position specifying unit 313 extracts the pixel region of the ship 100, the position specifying unit 313 acquires the coordinates of the lower center portion of the extracted pixel region. When the position specifying unit 313 acquires the coordinates of the center lower end of the pixel area of the ship 100, the coordinates on the map corresponding to the coordinates of the center lower end of the ship 100 are based on the mapping information stored in the mapping information storage unit 312. Is calculated. Note that the mapping information stored in the mapping information storage unit 312 includes, for example, a table that stores a plurality of video information coordinates and map coordinates in association with each other, or a transformation matrix (transformation matrix) from video information coordinates to map coordinates. ) And the like can be used to specify the position by the position specifying unit 313.

The size of the ship 100 is specified by the following processing, for example. First, the position specifying unit 313 extracts the pixel region of the ship 100 from the frame data of the video by the above-described processing. When the position specifying unit 313 extracts the pixel area of the ship 100, the position specifying unit 313 acquires the width and height of the extracted pixel area. When the position specifying unit 313 acquires the width and height of the pixel region of the ship 100, the monitoring camera 200-1 to 200-photographed with the ship 100 based on the coordinates on the map of the ship 100 specified by the above-described processing. 3 is calculated. When the distance between the ship 100 and the monitoring cameras 200-1 to 200-3 is calculated, the position specifying unit 313 calculates the actual size of the ship 100 based on the size of the pixel area of the ship 100 and the calculated distance. . Since the size (width, height) p of the pixel area of the ship 100 and the distance d between the ship 100 and the captured surveillance cameras 200-1 to 200-3 are inversely related, the size of the pixel area is large. The relationship between the length p, the distance d, and the actual size s of the ship 100 can be expressed as in Expression (1).
s = kpd (1)
However, k is a coefficient that varies depending on the resolution, viewing angle, and the like of the monitoring cameras 200-1 to 200-3, and needs to be calculated in advance.

  When the position specifying unit 313 specifies the position of the ship 100 on the map and the size of the ship 100 in step S <b> 4, the calculated size of the ship 100 is the size information included in the ship information acquired by the ship information acquiring unit 136 and the predetermined size. It is determined whether or not they match within the error range (step S5). When the position specifying unit 313 determines that the calculated size and the size information included in the ship information match within a predetermined error range (step S5: YES), the state determination unit 314 causes the ID detection unit 311 to set the ID. It is determined which monitoring cameras 200-1 to 200-3 photographed the detected video (step S6).

  If the state determination unit 314 determines that the port entry monitoring camera 200-1 has captured the video in which the ID detection unit 311 has detected the ID (step S6: port entry monitoring camera), the navigation state of the ship 100 is the port entry state. (Step S7). When the state determination unit 314 determines the navigation state of the ship 100, the log registration unit 330 displays the analysis result (ship ID, ship information, position information, navigation state) and video information analyzed by the analysis unit 310 and the log storage unit 340. (Step S8). Thereby, the log storage unit 340 stores the position information and the history of the navigation state in association with the ship ID. Moreover, if the state determination part 314 determines the navigation state of the ship 100 by step S7, the instruction | indication part 320 will output an unloading preparation instruction | indication to the unloader terminal 400-1 of the dock indicated by the arrival dock information contained in the acquired ship information. (Step S9). Thereby, the unloader can prepare for delivery by the time of docking. In addition, the instruction unit 320 generates and outputs a delivery instruction including arrival wharf information and cargo information included in the ship information to the deliverer terminal 400-2 (step S10). Thereby, the delivery operator can go to the wharf where the ship 100 arrives by the time of berthing and can prepare for delivery.

When the state determination unit 314 determines that the video detected by the ID detection unit 311 in step S6 is captured by the shore monitoring camera 200-1 (step S6: shore monitoring camera), the log storage unit 340 The navigation state history is read from the information corresponding to the ID of the ship 100 stored in The state determination unit 314 determines whether or not the ship 100 has already left the port by determining whether or not the ship 100 in which the ship 100 is in the departure state is stored in the read navigation state history. Determination is made (step S11). When determining that the ship 100 has not left the port (step S11: NO), the state determination unit 314 determines that the navigation state of the ship 100 is a landing state (step S12). When the state determination unit 314 determines the navigation state of the ship 100, the log registration unit 330 registers the analysis result and video information analyzed by the analysis unit 310 in the log storage unit 340 (step S13). Moreover, if the state determination part 314 determines the navigation state of the ship 100 by step S12, the instruction | indication part 320 will output an unloading instruction | indication to the shipper's terminal 400-1 of the wharf which the arrival wharf information of the acquired ship information shows (step). S14).
As a result, the unloader operates the unloading crane to start unloading work of the ship 100 that has berthed. In addition, since the unloader obtains a delivery preparation instruction when the ship 100 enters the port by using the unloader terminal 400-1, the unloader can complete preparations for the unloading work when the ship 100 lands. Therefore, the unloading work can be started immediately when the ship 100 shores.
Further, since the delivery operator has acquired a delivery instruction at the time of arrival of the ship 100 by the deliverer terminal 400-2 in step S10, the delivery work can be started immediately after the unloading work is completed.

When the instruction unit 320 outputs an unloading instruction in step S14, the ID detection unit 311 extracts the ship ID from the video taken by the berthing monitoring camera 100-2 in the same manner as in step S1, and the extracted ID is the ship. By determining whether or not it matches the ID of 100, it is determined whether or not the ship 100 has gone out of the image captured by the berthing monitoring camera 100-2 (step S15). In this process, when the unloading work of the ship 100 is completed and the ship 100 leaves the shore, the ship 100 goes out of the shooting range of the berthing monitoring camera 100-2, so it is determined whether or not the ship 100 has left the shore. To do. If the ID detection unit 311 determines that the ship 100 is not out of the video (step S15: NO), the ID detection unit 311 returns to step S15 and continues to monitor the video.
When the ID detection unit 311 determines that the ship 100 has gone out of the video (step S15: YES), the state determination unit 314 determines that the navigation state of the ship 100 is a rip-off state (step S16). When the state determination unit 314 determines the navigation state of the ship 100, the log registration unit 330 registers the analysis result and video information analyzed by the analysis unit 310 in the log storage unit 340 (step S17).

  In addition, when the state determination unit 314 determines in step S6 that the departure detection camera 200-3 has photographed the video detected by the ID detection unit 311 (step S6: departure monitoring camera), the ship 100 navigates. It determines with a state being a port departure state (step S18). When the state determination unit 314 determines the navigation state of the ship 100, the log registration unit 330 registers the analysis result and video information analyzed by the analysis unit 310 in the log storage unit 340 (step S19).

  In addition, when it is determined that there is no ship information corresponding to the ID detected by the ship information acquisition unit 316 in step S2 (step S2: NO), or the size and ship information calculated by the position specifying unit 313 in step S5. When it is determined that the size information included in the information does not match within a predetermined error range (step S5: NO), or when the state determination unit 314 determines in step S11 that the ship 100 has already departed ( Step S11: YES), the state determination unit 314 determines that the ship 100 is a suspicious ship (Step S20). When the state determination unit 314 determines that the ship 100 is a suspicious ship, the log registration unit 330 registers the analysis result and video information analyzed by the analysis unit 310 in the log storage unit 340 (step S21). Moreover, if the state determination part 314 determines the ship 100 as a suspicious ship by step S20, the instruction | indication part 320 will output the warning instruction | indication which contains the positional information on the ship 100 to the guard terminal 400-3 (step S22). Thereby, the guard boat can be dispatched to the position of the suspicious ship 100 such as the ID is not registered, the ship information does not match the size, or the entry / exit state is not consistent.

  Thus, according to the present embodiment, the ship 100 causes the port lights to blink based on the ID of the ship 100. In addition, each of the monitoring cameras 200-1 to 200-3 captures an image including the ship 100. Furthermore, the ID detection unit 311 of the port entry / exit management device 300 extracts the blinking pattern of the port lights of the ship 100 from the images taken by the monitoring cameras 200-1 to 200-3, and detects the ID of the ship 100. Thereby, the introduction of the system into the ship 100 can be suppressed only by introducing a circuit that blinks a port light that is normally installed in the ship 100, and the introduction cost into the ship 100 can be reduced.

  Further, according to the present embodiment, the position specifying unit 313 determines the position of the ship 100 on the map based on the mapping information from the image coordinates to the coordinates on the map stored in advance in the mapping information storage unit 312 and the image. Is identified. Thereby, the port entry / exit management apparatus 300 can manage the position of the ship 100 in the port. For this reason, the land facility regulates maritime traffic, so that the behavior of a plurality of ships can be grasped at any time.

  Moreover, according to this embodiment, the state determination part 314 is based on which surveillance camera 200-1 to 200-3 image | photographed the image | video which the ID detection part 311 detected ID of the ship 100 according to which ship 100. Determine the navigational state of the. Thereby, the entrance / exit management apparatus 300 can manage the navigation state in the port of the ship 100.

  Moreover, according to this embodiment, the instruction | indication part 320 shows instruction information which shows the instruction | indication of the operation | work performed with respect to the ship 100 based on ID of the ship 100, and the navigation state of the ship 100 to each worker terminal 400-1. Output to 400-3. Thereby, it is possible to cooperate with the information on the ship 100 and a system such as unloading, delivery, and security, and the operator can perform efficient port operations.

  Moreover, according to this embodiment, the output part 350 outputs an image | video, ID of the ship 100, a navigation state, position information, etc. outside via an external network. Thereby, the state of a port can be acquired from the outside of a land facility through a network.

As described above, the embodiment of the present invention has been described in detail with reference to the drawings. However, the specific configuration is not limited to the above, and various design changes and the like can be made without departing from the scope of the present invention. It is possible to
For example, in the present embodiment, the port monitoring camera 200-1 is installed so as to be reflected in the image taken by the port light of the ship 100 entering the port, and the port light of the ship 100 leaving the port departure monitoring camera 200-3 is taken. The case where the ID detection unit 311 acquires the ID of the ship 100 from the port lights of the images captured by the monitoring cameras 200-1 to 200-3 has been described. The monitoring camera 200-1 is installed so as to be reflected in the image taken by the starboard light of the ship 100 entering the port, and the departure monitoring camera 200-3 is provided so as to be reflected in the image taken by the starboard light of the ship 100 that leaves the port. The same effect can also be obtained when the ID detection unit 311 acquires the ID of the ship 100 from the starlight of the video imaged by the monitoring cameras 200-1 to 200-3. Since the starboard light is a blue light, the detection of the starlight by the ID detection unit 311 is performed by the ID detection unit 311 in each frame of the video information, for example, when the color space of the video information is expressed in the YCbCr format. This is performed by determining whether there is a portion where the blue color difference component (Cb) is equal to or greater than a predetermined threshold value.

In addition, although this embodiment demonstrated the case where the port entry monitoring camera 200-1, the berthing monitoring camera 200-2, and the departure monitoring camera 200-3 were provided as a monitoring camera, the number and use of a monitoring camera are not restricted to this. .
Moreover, although this embodiment demonstrated the case where the unloader terminal 400-1, the delivery person terminal 400-2, and the guard terminal 400-3 were provided as a worker terminal, the number of worker terminals and a use are restricted to this. I can't. Further, a speaker may be installed instead of the worker terminal, and the instruction unit 320 may output an instruction by voice.

  Moreover, although this embodiment demonstrated the case where the ID detection part 311 acquires ID of the ship 100 from the port light of the image | video which the surveillance cameras 200-1 to 200-3 image | photograph, it is not restricted to this. For example, since there is a possibility that blind spots may be generated in the monitoring cameras 200-1 to 200-3 due to generation of fog on the channel, overlapping of the ships 100, etc., the monitoring cameras 200-1 to 200-3 have as wide a field of view as possible. It is necessary to ensure. As shown in FIG. 1, when the entrance and the exit of the port are the same, the image taken by the port entry monitoring camera 200-1 not only shows the port lights of the vessel 100 entering the port, but also the starboard lights of the vessel 100 leaving the port. Is reflected. In addition, the video taken by the departure monitoring camera 200-3 not only shows the port lights of the ship 100 leaving the port, but also shows the star lights of the ship 100 entering the port. Therefore, the ID detection unit 311 detects the ID from the starboard lamp and the port lamp in the above-described step S1, and the state determination unit 314 (traveling direction determination unit) detects the monitoring cameras 200-1 to 200 that have captured the video in step pS6. -3 and the light color of the ship 100 determine the navigation state. For example, when the starboard light of the ship 100 is detected in the image captured by the port entry monitoring camera 200-1, the state determination unit 314 determines that the ship 100 is in the departure state. In this way, by providing a plurality of monitoring cameras on the land facility, the blind spots of the monitoring cameras are reduced, and the state determination unit 314 determines the traveling direction of the ship based on the light color of the ship 100, thereby overlooking the ship 100 in the harbor. Can be reduced.

  Moreover, although this embodiment demonstrated the case where the entrance / exit management system was installed in a port and the condition of the ship 100 in a port was managed, it is not restricted to this, For example, a monitoring camera is installed in a strait etc. at fixed intervals. The state determination unit 314 manages the ship 100 in the strait by determining the navigation state such as “strait intrusion”, “passing area 1”, “passing area 2”, etc. according to the installation position of the monitoring camera. May be.
