As shown in fig. 1 and 2, 4 cameras C1 to C4 are provided on the left side surface of the hull 4 at intervals along the entire longitudinal direction thereof, and 4 cameras C5 to C8 are provided on the right side surface of the hull 4 at intervals along the entire longitudinal direction thereof. Further, a camera C9 is provided at the front end of the hull 4, and a camera C10 is provided at the rear end. Each of the cameras C1 to C10 is configured to capture an image of the water surface W including a part of the hull 4, which is the surrounding condition of the hull 4, and output an image signal of the captured image, with the cameras directed downward. For this purpose, the cameras C1 to C10 are provided so as to protrude outside the hull 4. As shown in fig. 3, the imaging regions R1 to R10 of the cameras C1 to C10 are set so as to cover the entire region surrounded by the thick line frame of the hull and so that the imaging regions of adjacent cameras partially overlap.
Further, a draft detection unit 10 is provided at an upper edge portion of the left side surface substantially at the center in the longitudinal direction of the hull 4. The draft detection unit 10 is formed of a doppler radar that detects a distance from the detection unit 10 to the water surface W and outputs a signal. The draft detection means 10 may be constituted by a pressure-receiving type detection means that measures a pressure acting on the outer surface of the hull 4 and calculates the draft of the hull based on the measured pressure. Further, the draft control device may be configured by a detection means for calculating the draft value of the hull from the weight of the load loaded on the hull 4 and the amount of ballast water in the ballast tank of the hull 4.
As shown in fig. 3, the cameras C1 to C10 are connected to a PoE (Power Over Ethernet) hub 12 via LAN cables. A processor 14 is connected to the PoE hub 12, and the processor 14 has a function of synthesizing an entire overhead image including the hull 4 and the periphery of the hull 4 based on the image signals of the cameras C1 to C10 and outputting a signal including the overhead image. Further, a marine device 16 such as a GPS, compass, bathometer, and wind/wind speed meter, and an engine information detector 18 such as a rudder angle, a rotation speed of a propeller shaft, and a rotation speed of a stern propeller/bow propeller are connected to the PoE hub 12 through a communication converter 20. Furthermore, the GPS of the marine vessel 16 is able to detect the heading and speed of the vessel 2. To the PoE hub 12, an access point a1 through which a display terminal D1 as a display device disposed in the bridge 6 can be wirelessly connected and an access point a2 through which a display terminal D2 as a display device disposed outdoors can be wirelessly connected are connected. A plurality of access points a1 and a plurality of access points a2 are provided as needed. Further, a water detection unit 10 is connected to the PoE concentrator 12.

Fig. 4 illustrates an example of the first display unit D1 or the second display unit D2. The entire overhead image 26 including the ship hull 4 and the periphery of the ship hull 4 synthesized by the processor 14 based on the image signals of the plurality of cameras C1 to C10 is displayed on the substantially left half of the display 24 of the first display unit D1 or the second display unit D2. Further, the overhead image 26 includes a tug T that assists the movement of the vessel 2 and a shore wall B for the landing of the vessel 2. Further, the processor 14 displays the current latitude, longitude, heading, ship speed, water depth, draft value, rudder angle, rotation speed of the propeller shaft, and rotation speed of the stern propeller/bow propeller of the ship 2 on the remaining portion of the display 24 for display based on the signals from the marine vessel 16 and the engine information detection unit 18 described above. Further, the processor 14 displays an arrow 28 corresponding to the heading direction and an arrow 30 corresponding to the wind direction superimposed on the center of gravity of the hull 4 of the overhead image 26. For arrows 28 and 30, the respective lengths may be made to correspond to boat and wind speed, respectively.
Next, the image synthesis process performed by the processor 14 will be described with reference to fig. 5. The processor 14 includes an input/output device for executing the image synthesizing process described above, a storage device in which a command to execute the image synthesizing process is stored, a central processing unit, a timer, and the like.
First, the processor 14 receives image signals of the cameras C1 to C10 (step S1). Next, the processor 14 synthesizes 1 overhead image including the hull 4 based on the image signals of the cameras C1 to C10 received at step S1 in accordance with a well-known method (step S2). The synthesis of the overhead image by the processor 14 in step S2 can use any known method, for example, the method shown in patent document 1.
Further, the processor 14 receives the output signals of the marine vessel 16 and the engine information detector 18 (step S3), and further creates a synthetic image in which the current latitude, longitude, heading, ship speed, water depth, draft value, rudder angle, rotation speed of the propeller shaft, and rotation speed of the stern propeller/bow propeller of the ship 2 as explained with reference to fig. 4 are superimposed together with the overhead image synthesized at step S2 and displayed (step S4). Its composite image signal is output to the first display unit D1 and the second display unit D2 through the access point a1 and the access point a2 (step S5). Based on the output signal, the composite image shown in fig. 4 is displayed on the display device 24 of the first display cell D1 and the second display cell D2, for example.
In addition, in the present embodiment, the first display unit D1 and the second display unit D2 have a function of performing communication with the processor 14 including instructions to the processor 14. For this reason, each display 24 of the first display unit D1 and the second display unit D2 has a touch screen function capable of transmitting a signal to the processor 14 by touching the screen.
On the other hand, a camera C11 for monitoring cargo handling work on the deck D facing the deck D of the hull 4 is provided at the center of the front end of the bridge 6 or at a position higher than the bridge 6, and the camera C11 is connected to the PoE hub 12 via a LAN cable. The operation button 32 is displayed on the display monitor 24, and when the operator touches the operation button 32, the state on the deck D of the ship body 4 imaged by the camera C11 is displayed on the entire display monitor 24.
Further, the first display unit D1 and the second display unit D2 have a function of displaying a part of the overhead image including the position of the display 24 on the screen by touching the screen with a finger or the like at an arbitrary position in the area around the hull 4. The function may be provided on the display unit D1 or the display unit D2, respectively. Further, instead of enlarging and displaying a part of the overhead view image, the image captured by one of the cameras C1 to C10 closest to the arbitrary position of the peripheral area may be enlarged and displayed on the screen of each display monitor 24. Thereby, the driver or the operator can enlarge and display the image of the specific portion on the screen, and therefore, the details of the specific portion can be more easily visually recognized. Further, it is also possible to display thin lines corresponding to the imaging regions of the cameras C1 to C10 in the area around the ship 2 on the screen of the display 24 so that the driver or the operator can easily specify the area of the enlarged image.
Further, the processor 14 is configured to perform display showing the operation of the second display unit D2 on the first display unit D1 when the second display unit D2 receives the output of the processor 14 and displays an image including the synthesized image. Specifically, the display unit 34 on the display 24 for display of the first display unit D1 is activated. Instead, the display unit 34 may be provided near the outside of the first display unit D1.
As described above, according to the voyage support system of the marine vessel of the present embodiment, the composite image including the hull 4 and the surroundings of the hull, which is created by the processor 14 based on the image signals of the plurality of cameras C1 to C11, is displayed on both the first display unit D1 provided on the marine vessel 2 and the second display unit D2 provided on the tug T. Therefore, the ship pilot of the ship 2 can appropriately operate the propulsion device and steering device of the ship 2 and further appropriately operate the side thruster while viewing the image displayed on the first display means D1, and can appropriately give an instruction to the tug driver on the side of the tug T, while the tug driver can more accurately grasp the instruction content from the ship pilot and the background thereof while viewing the image displayed on the second display means D2. Here, the tug pilot corresponds to the operator of the relevant vessel of the invention. That is, since the image displayed on the second display means D2 includes the hull 4 of the ship 2 and the periphery of the hull, the tug driver can sufficiently grasp the situation of the ship 2 on the opposite side of the tug T and the situation of the periphery of the tug itself including the orientation of the tug T with respect to the ship, and thus can grasp the instruction content from the ship driver and the background thereof more accurately.
With the navigation support system for a marine vessel of the present embodiment, the processor 14 outputs a signal showing the traveling direction and speed of the marine vessel 2 together with the composite image, and the first display unit D1 and the second display unit D2 display an image including the traveling direction and speed of the marine vessel 2 together with the composite image including the hull 4 and the surroundings of the hull, and therefore, the tug driver can grasp the current traveling direction and speed of the marine vessel 2.
Further, since the processor 14 displays the image in which the arrow 28 indicating the traveling direction and the speed of the ship 2 is superimposed on the composite image, the ship pilot and the tug pilot can visually and easily grasp the correlation between the traveling direction and the speed of the ship 2 and the direction of the ship.
Further, with the vessel navigation support system of the present embodiment, the processor 14 outputs a signal including the wind direction and the wind speed around the vessel 2 together with the composite image, and the first display unit D1 and the second display unit D2 display an image including the wind direction and the wind speed of the vessel 2 together with the composite image, and therefore, the vessel driver and the tug driver can grasp the current wind direction and the current wind speed.
Further, the processor 14 displays an image in which an arrow image indicating the wind direction and the wind speed around the ship 2 is superimposed on the composite image, and therefore, the ship pilot and the tug pilot can visually and easily grasp the correlation between the wind direction and the wind speed around the ship 2 and the orientation of the ship.
Further, the navigation support system for a ship of the present embodiment includes the operating condition detection unit 18 that is provided in the ship 2 and detects and outputs the operating condition of the drive device of the ship 2, the processor 14 receives the output of the operating condition detection unit 18 and outputs a signal indicating the operating condition together with the composite image, and the first display unit D1 and the second display unit D2 display the image indicating the operating condition together with the composite image, so that the tug driver can grasp the operating condition of the drive device of the ship 2.
In the navigation support system of the present embodiment, the first display unit D1 and the second display unit D2 have a function of communicating with the processor 14 including an instruction to the processor 14, and when the second display unit D2 receives an output of the image processing unit 14 and displays an image including a synthesized image, the processor 14 displays the received image on the first display unit D1 or the display unit 34 provided in the vicinity thereof.
Thus, the vessel pilot can know that the second display unit D2 of the tug T has received the output of the processor 14 and is displaying an image including the composite image, and can give an instruction to the tug pilot in advance of this.
Further, a storage unit M1 is provided at the bridge 6 of the ship 2. The processor 14 is configured to correlate the navigation information such as the GPS, compass, bathometer, and anemometer obtained from the navigation device 16 and the engine information such as the rudder angle, the rotational speed of the propeller shaft, and the rotational speed of the stern propeller/bow propeller obtained from the engine information detector 18 with the signal of the composite screen and output the signal to the storage unit M1 as numerical information. The storage unit M1 can associate the received navigation information and engine information with the above-described composite image and store them continuously in time series.
Therefore, in the ship 2, the image at the time of going ashore under similar conditions (weather, cargo load, etc.) in the past is analyzed using the information on the operation and environment of the ship 2 which is associated with the above-described composite image and stored in the storage means M1 together with the composite image, thereby enabling the advance practice of going ashore and enabling the improvement of the ship-moving method involving going ashore, for example, the improvement of the economical operation method or the ship-moving method for improving safety.
In the navigation support system for a ship according to the above-described embodiment, there are 1 tug T assisting the ship 2 to be pulled in and out of the shore, but there may be a case where 2 or more tug assisting the ship 2 to be pulled in and out of the shore. In that case, a third display unit D3 is provided on the second or more tugs in addition to the first display unit D1 and the second display unit D2, and the third display unit D3 is connected to the processor 14 through the access point a 2. The third display unit D3 has the same function as the second display unit D2. In addition to the display unit 34, a second display unit is additionally provided on or near the display 24 of the display terminal D1, and when the third display unit D3 receives the output of the image processing unit 14 and displays an image including a synthesized image, the processor 14 displays the received image on the first display unit D1 or the second display unit 34 provided near the first display unit D1.
Accordingly, the ship pilot can know that the tug T and the second display unit D2 and the third display unit D3 of the second tug have received the output of the processor 14 and are displaying an image including a composite image, and can give an instruction to the tug pilot on the premise that the ship pilot has the composite image.
In the above-described embodiment, the second display unit D2 is provided on the tug T, but instead of this, the second display unit D2 may be disposed on a relevant offshore facility, not shown, to which the ship 2 is to be connected, for example, an offshore oil facility, an offshore wind power generation facility, a floating dock, or another floating structure, so that the operator of the relevant offshore facility can view the second display unit D2 when the ship 2 is connected to the relevant offshore facility.
According to this configuration, since the operator of the relevant offshore facility can easily grasp the situation around the ship by viewing the image displayed on the second display unit, information can be shared with respect to the situation around the ship when performing an operation to connect the ship to the relevant offshore facility, and the like, it is possible to significantly enhance communication between the ship driver and the operator of the relevant offshore facility, and to improve the safety and efficiency of the operation to connect the ship to the ship.
Further, when the ship 2 is on board with another related ship, the second display unit D2 may be disposed on another related ship to which the ship 2 is on board instead of the tug T. For example, when the ship 2 is a tanker, the tanker needs to be docked with the ship, and the operator of the ship can easily grasp the situation around the tanker by viewing the image displayed on the second display unit, thereby improving the safety and efficiency of the docking operation.
In the above-described embodiment, the second display unit D2 is provided on the tug T, but instead, the display unit D2 may be disposed on the side of the quay wall B on which the ship 2 is to be landed so that the operator on the quay wall B can view the second display unit D2.
This enables the operator on the quay wall B side to more accurately grasp the contents of the instruction from the ship driver and the background thereof while viewing the image displayed on the second display means D2. That is, since the image displayed on the second display unit D2 includes the hull 4 of the ship 2 and the periphery of the hull 4, the operator on the side of the quay wall B can sufficiently grasp the state of the ship 2 on the side opposite to the quay wall B and the state of the periphery of the ship 2, and thus can grasp the instruction content from the ship driver and the background thereof more accurately.
Further, if necessary, it is also possible to arrange display means having the same function as the second display means D2 on both the tug T and the shore wall B, and as a result, the tug driver and the operator on the shore wall side can view the same image as the first display means D1. In this case, a necessary number of display means can be arranged according to the number of tugs T and the number of operators on the shore wall B.
Fig. 6 shows another embodiment. The processor 14 is configured to be able to output as numerical information from the access point a2 by correlating the navigation information such as GPS, compass, water depth indicator, and wind direction/wind velocity indicator obtained from the navigation device 16 and the engine information such as the rudder angle, the number of revolutions of the propeller shaft, and the number of revolutions of the stern propeller/bow propeller obtained from the engine information detector 18 with the signal of the composite screen. On the other hand, the ship-boarding support apparatus S on the ground upper side is provided with a second display unit D2 and a storage unit M2. The second display unit D2 can receive the navigation information or the engine information together with the signal of the composite screen as numerical data from the access point a 2. The storage unit M2 may store the received information in time series continuously together with the composite image.
According to the other embodiment, the composite image including the hull 4 and the surroundings of the hull 4 created by the processor 14 based on the image signals of the plurality of cameras C1 to C10 is displayed on both the first display unit D1 provided on the ship 2 and the second display unit D2 of the ship-driving support apparatus S arranged on the land side. Therefore, the ship-boarding support facility S on the land side can accurately grasp the landing state of the ship 2. Further, in the ship-boarding support facility S on the land side, the information on the operation and environment of the ship 2, which is associated with the above-described synthetic image and stored in the storage unit M2 together with the synthetic image, is analyzed, whereby it is possible to realize an improvement in a boarding method, for example, an improvement in an economical operation method or a boarding method for improving safety.
