Description

Port video control method and system {Method and system port video control}

The present invention relates to a control system, and more specifically, to a port image control method and system.

In general, the video control system identifies the control targets based on control video information collected by video surveillance apparatuses (eg, Closed Circuit Television) installed in multiple areas. In particular, the port control system is used to monitor the safety operation and compliance with vessels operating in the seas where the traffic volume such as ports and coastal areas are congested or the navigation conditions are unfavorable. The port control system monitors at the time of vessel entry, vessel departure, anchorage, for example through closed-circuit television (CCTV), and pan / tilt / zoom (overall) of each CCTV Control, which is also called PTZ), has been controlled in such a way that the CCTV is directed to the corresponding position when the operator clicks the control screen.

In general, CCTV equipment is installed independently and the role of detecting an object by the signal processing function of the image itself and the research to track it have been progressed to the image processing function. In other words, it is rarely desired to improve the accuracy by combining it with other sensing equipment, and in particular, the method and processing performance of the combination in a marine control system have been rarely improved.

In addition, there are more than 1000 tons of ships entering and leaving the port, and the area to be controlled is very wide. Therefore, it is not easy to install CCTV in each place where monitoring is required, and there is a problem such as an increase in cost. Therefore, one CCTV usually monitors several places. In particular, large vessels cannot be monitored by a single CCTV, so they must be monitored by using multiple CCTVs.

However, in the existing port control system, operators have to monitor the ships while controlling the pan / tilt of each CCTV individually. Therefore, in monitoring a large ship and the like, it is not possible to control several CCTVs at the same time, there is a disadvantage that causes inconvenience caused by individually controlling several CCTVs. In particular, when an anchored ship has an incident (eg, a lockout), an accident (fall, damage, etc.) and needs to be urgently monitored for the vessel and its surroundings, the operator finds relevant CCTVs, Inconvenience such as several times of PTZ operation occurs, and therefore it takes a lot of time to comprehensively recognize the situation.

In addition, there are hundreds of ships entering and leaving the port every day, and it is not easy to visually monitor hundreds of ships. Some vessels have already been verified and have no need to be monitored, but since there is no filtering on these vessels, all information about the vessels is displayed on the screen, so control may not be performed efficiently.

On the other hand, as a method of providing another control service by transmitting the location information to the CCTV device based on the AIS (Automatic identification system) location information, simply show the AIS location information on the CCTV image screen to the mapped location information of the CCTV There is a way to exhibit.

As a method of providing another control service, for example, Korean Patent Laid-Open No. 2011-0116842, "Method of displaying an electronic chart of a ship navigation system using augmented reality" and other vessels according to the electronic chart in actual images There is also a method of providing an augmented reality image by augmented reality processing the flight information of.

In particular, the communication unit 50 receives location information (latitude and longitude coordinates) of the terminal, and receives the location information of the terminal in association with the terminal identification information (eg, the terminal ID). It may be provided to the map editor 30, converted into coordinate information, and stored in the mapping table 40.

The ship information processing unit 60 collects ship related information from the port operation information system 3 through the communication unit 50. In addition, the vessel information processing unit 60 may collect information on the vessel of interest through offline or through the communication unit 50. Here, the ship of interest is a ship requiring special control, for example, may be a ship requiring special control in connection with illegal work such as smuggling, smuggling. Information about the vessel of interest may be collected via offline, such as a fax or a public letter, or may be collected from a police station system such as a marine police. The information collected through the offline may be provided to the ship information processing unit 60 through an input interface.

The image processing unit 90 is configured to process an image provided from each surveillance camera and provide it to the control processing unit 70. The technology for processing an image provided from the surveillance camera is a well-known technique, and thus a detailed description thereof will be omitted.

4 is a view showing a structure of a control processing unit according to an embodiment of the present invention.

As shown in FIG. 4, the control processing unit 70 according to an embodiment of the present invention includes a linked camera processing unit 71 and a ship processing unit 72 of interest, and in addition, a grouping processing unit 73 and a search processing unit ( 74) may be further included.

The associated camera processing unit 71 is configured to process images from surveillance cameras located within a setting range according to an event, and control the operation of the surveillance camera. The associated camera processor 81 may be configured to control an operation of the surveillance camera, in particular, a pan tilt zoom (PTZ).

When the entry / exit event occurs, the associated camera processing unit 71 processes an image from surveillance cameras located within a set range based on the position of the berth or the vessel where the entry / exit occurrence occurred and automatically controls the PTZ of the surveillance camera.

On the other hand, although the actual vessel anchored at the dock due to delay in entering and leaving port information of the port operation information system 3, the corresponding information may not be displayed on the port image control system 1. In this case, when the arrival of the ship is confirmed by the communication with the terminal of the field user, and the berth icon or the like is selected, the associated camera processing unit 71 can immediately monitor the vessel.

The linked camera processing unit 71 may automatically control the PTZ based on the relationship between the position of the berths or ships and the position of the surveillance camera. In addition, the operation of controlling the PTZ of the surveillance camera based on the information of the vessel entering and leaving can be different for each vessel. For example, based on the size of the vessel, the left and right angles, the vertical angle and the zoom level for the PTZ of the surveillance camera can be different. Alternatively, the time to perform the PTZ of the surveillance camera may be different for each ship. Alternatively, the direction of controlling the PTZ of the surveillance camera may be changed depending on whether the ship is entering or departing. For example, when a vessel arrives, the surveillance cameras can be controlled to perform pan operation from the sea direction to the port direction. When the vessel departs, the surveillance cameras perform pan operation from the port direction to the sea direction. Can be controlled.

In addition, when the event occurs, the associated camera processor 71 controls a plurality of cameras to monitor the berths or ships. In addition, when an event occurs, a plurality of cameras may be controlled to monitor different areas. In addition, the camera may not only view a fixed area, but also preset the preset coordinates for the camera, and tour the camera by varying the preset coordinates according to the vessel size. For example, set 6 coordinates for the first berth camera (for example, (100, 100), (200, 100), (300, 100), (300, 200), (200, 200), ( 100, 200)) and more than a set size, for example, when a vessel of 4000 tons enters the port, the camera is controlled to monitor the vessel while sequentially moving to six setting coordinates. Ships smaller than the set size For example, when 500 tons of ships enter, four of the six set points (eg, (100, 100), (200, 100), (200, 200), (100) , 200) is controlled to monitor the vessel while moving sequentially.

When an emergency event occurs, the linked camera processor 71 processes an image from surveillance cameras located within a setting range based on the position of the berth or the vessel where the emergency event occurred and automatically adjusts the PTZ of the surveillance camera. To control.

Alternatively, the associated camera processor 71 may control the PTZ of the surveillance camera based on the position of the terminal. For example, the PTZ of the surveillance camera can be controlled based on the relationship between the position of the terminal and the position of the surveillance camera (for example, a difference between latitude and longitude coordinates).

Meanwhile, the associated camera processor 71 may perform image collection and operation control from surveillance cameras to which the authority control is granted to the corresponding account, based on the authority information for each account, which is filtering information.

The ship processing unit 72 of interest may process the display of the vessel to be distinguished from other vessels based on the information on the vessel of interest provided from the ship information processing unit 60. The ship processing unit 72 of interest, for example, may be displayed on the screen by differently adjusting the color, size, and shape so that an icon for the ship of interest is distinguished from an icon of another ship. In addition, when the information on the information of the ship of interest is entered, the ship of interest 72 is a notification indicating that the ship of interest is entering or departing so that the operator quickly recognizes the ship of interest and the control on the ship is precisely made. Are displayed on the screen, and the vessel indication of interest is different as described above.

In addition, the ship processing unit 72 of interest may request PTZ control of surveillance cameras related to the ship of interest to the associated camera processing unit 71 for monitoring the ship of interest. In this case, the linked camera processor 71 controls the PTZ of the surveillance cameras located within the set range based on the position of the berth or the vessel in which the vessel of interest is located, for example, by enlarging the zoom level of the surveillance camera to the greatest extent. The PTZ of the monitoring cameras may be controlled to facilitate checking of the image output on the screen, or to monitor a specific position of the vessel of interest, for example, around the entrance and exit where embarkation and disembarkation take place.

Meanwhile, the grouping processing unit 73 is configured to group the fixed equipment including the surveillance camera. In an embodiment of the present disclosure, the grouping processing unit 73 checks the zoom phase of the map output on the screen, collects information of the surveillance camera (and / or field terminal) for each map image virtual zone, The grouping process is performed for each virtual region of the map image by the zoom level. The grouping processor 73 may collect and group information on the surveillance camera and / or the field terminal to which the authority control is granted to the corresponding account based on the information stored in the mapping table and the authority information for each account. The zoom level of the map may vary in steps of 5M, 50M, 100M, for example, based on the reference position. For example, when the zoom level of the map is 5M, a surveillance camera, a field terminal, a ship, or a berth may be grouped for each map image virtual zone included in a corresponding range.

The search processing unit 74 may be configured to perform information search of a surveillance camera, a terminal, a ship, and the like.

On the other hand, the screen output unit 80 of the port image control system is configured to output the processing result of the control processing unit 70. The screen output unit 80 is configured to display a map and to display the processing result of the control processing unit 70 on the map. On the other hand, the images captured by the surveillance cameras located within the setting range may be integrated by the image processor 90 and the screen output unit 80 to be output on the screen.

Next, a control method based on a port image control system having such a structure will be described.

5 is a flowchart illustrating a control method according to an embodiment of the present invention.

When the operator of the operation room having a predetermined account logs in to the port video control system, the port video control system 1 captures an image captured by a surveillance camera in a management area that has been given authority control to the corresponding account, and a field terminal in the management area. Find information related to the current status, the status of the berths in the management area (S100). The port image control system 1 selectively outputs images captured by a surveillance camera located in a corresponding management area, receives location information of field terminals through an exchange server 3, and receives received location information of field terminals. Can be converted to coordinate information. In addition, the location of the field terminal may be mapped on the map to output the field terminal, and for example, an icon corresponding to the field terminal may be output. According to this process, the field terminals collected for each virtual zone on the map are output, and the operator can check where the users are located and how the patrol is performed for each virtual zone on the map of the management area. At this time, the patrol information may be additionally output in response to the field terminal on the map, so that the patrol may patrol the corresponding area.

When an event occurs in this state (S110), the port image control system 1 performs a control process according to the event. First, the information on the corresponding vessel is obtained based on the location where the event occurred (S120). Obtain information on the vessel located at the berth where the entry / exit event occurred and information on the vessel where the emergency event occurred, and obtain information about the vessel located at the berth where the event occurred or the vessel on which the event occurred from the port operation information system can do. In addition, when the event is not issued due to the delay in entering the port entry / departure of the port operation information system and the information is not delivered to the port image control system, when a manual confirmation request is received through the terminal of the field user, the situation room The operator can manually trigger an event by selecting the corresponding berth icon or the like.

Then, the monitoring cameras located within the set range are found based on the location where the event occurs (S130). The image obtained while controlling the PTZ of the detected surveillance cameras is output on the map. At this time, the harbor video control system 1 is the position associated with the event (for example, the location of the berths or vessels where the entry and exit events occurred, the position of the berths where the vessel occurred emergency, the location of the surveillance camera or sensor Based on the position, etc.), the surveillance cameras included in the set range are searched for, and the images of the surveillance cameras are collected and output.

On the other hand, in the above step (S130), the port video control system 1 ignores the event, if the location associated with the event is not included in the management region / management equipment set in the account, the location related to the event When included in the management area / management equipment set in the account, it is possible to perform control processing according to the corresponding event.

In addition, when the vessel located in the berth of the event or the vessel in which the event occurred is a vessel of interest, the harbor video control system 1 notifies the operator that there is a vessel of interest and recognizes an icon corresponding to the vessel of interest. While displaying on the screen, it is displayed differently from other ship icons (S140). At this time, the port image control system 1 compares the information on the vessel located in the berth where the event occurred or the vessel in which the event occurred with the vessel information of the interest obtained from the port operation information system, and determines whether the vessel is the vessel of interest. You can decide whether or not.

The harbor image control system 1 collects and outputs images of surveillance cameras (S150), and collects and outputs images from the surveillance cameras while automatically controlling PTZ of the surveillance cameras (S160). In this case, PTZ control of the monitoring cameras may be differently performed according to the event type.

6 is a diagram illustrating an example of a control image output according to an exemplary embodiment of the present invention.

As shown in FIG. 6, when an event occurs while the field terminal icons are displayed on the map, images acquired by the monitoring cameras may be displayed on the screen in the form of a pop-up window. In particular, as the surveillance cameras are automatically controlled at the same time, in particular, PTZ control of the surveillance cameras is automatically performed, so that an image that is easier to monitor can be obtained and output.

Conventionally, when a ship enters or departs a port manually, surveillance cameras are manually searched to control PTZ individually, whereas according to an embodiment of the present invention, a surveillance camera is located within a set range based on the position of a corresponding ship or berth PTZ at the same time Images can be obtained while controlling. Therefore, more convenient monitoring is achieved, and the time required for acquiring related images can be reduced. Therefore, even when an urgent event (fall, damage, smuggling, etc.) occurs, the related image can be obtained quickly and accurately, so that reliable control can be achieved.

In addition, the ships can be quickly recognized by displaying and displaying information on ships of interest by comparing the information of ships acquired through linkage with the port operation information system and ships of ships acquired offline and online. Can perform reliable control.

On the other hand, in the above step (S130), if the information of the vessel obtained according to the event is included in the filtering information, the control process for the vessel can be omitted. It is not easy for ships that enter and leave the port every day to visually monitor hundreds of ships. According to an embodiment of the present invention, the control may not be performed on ships that have already been verified and need not be monitored. Therefore, all information about the ship is displayed on the screen to prevent the case that the control is not made efficiently. In addition, when the actual ship has departed, but the information about the vessel is not deleted due to the delay in entering the port of the port operation information system, information about the vessel can be removed from the screen display by filtering.

On the other hand, in the state that the field terminals are output on the map, it is possible to check the image from the surveillance camera in the vicinity of any field terminal or the vessel. When the field terminals and the vessel are output on the map, if the image confirmation is requested for any field terminal or the area in which the vessel is located, the harbor video control system 1 sets the range based on the position of the selected field terminal or the vessel. Search for the surveillance cameras located within, and output the image from the searched surveillance cameras. At this time, the PTZ can be automatically controlled based on the relationship between the position of the field terminal or the vessel and the position of the surveillance camera. For example, based on the difference between the position (x1, y1) of the surveillance camera and the position (x2, y2) of the field terminal, that is, (x1-x2, y1-y2), the PT of the surveillance camera can be controlled to move the angle of view. Can be. Accordingly, the surveillance camera can be photographed on the site of the site terminal or an arbitrary vessel, and as a result, the operator can grasp the more accurate site situation through the image from the surveillance camera. Of course, the zoom of the surveillance camera may be controlled to enlarge / reduce an image from the surveillance camera.

In addition, the range of finding the surveillance camera based on the location of the field terminal or the vessel may be subdivided by class, and the surveillance camera search may be performed by class. For example, divide the search scope into the primary, secondary, and tertiary grades (for example, primary grade range <secondary grade range <third grade range), first search the range of primary grades, After that, you can search the range of the second grade and the range of the third grade sequentially. When there is no surveillance camera in the range of each class, or according to the selection, the surveillance camera search in the range of the next class can be performed.
