Definitions

  • the present invention relates to a frontier monitoring system for monitoring frontiers, borders or demarcations between countries, factory grounds, school grounds, prison grounds, and areas in general, but in particular frontiers that may be present at a waterfront, for example a harbour quay or beach.
  • fences or other physic separation means may be placed at that frontier.
  • physic separation means cannot be used, e. g. the frontier between a moored (e.g. foreign) ship and a (e.g. domestic) harbour quay.
  • the present invention aims to offer a system and a method for monitoring such a frontier.
  • Japanese patent application JP 2005-145602 discloses a harbour monitoring system capable of detecting the intrusion of persons on the quay side of a container terminal and a container crane.
  • This known monitoring system comprises a monitoring camera and a laser sensor positioned at a point above the quay on a container crane so as to monitor the quay from above.
  • This known system has the disadvantage that it is arranged for monitoring the whole quay area, even when there is no ship moored and the chances of detection intruders is negligible.
  • an undesirably and unnecessarily large quantity of monitoring data (such as video images) is produced and processed. If video images produced by such a system are watched by human observers (e.g. security personnel), an unnecessary large number of observers is necessary.
  • the present invention provides a system for monitoring a frontier between two areas, the system comprising:
  • the transportation means the presence of which can be detected may be ships, cars, trucks, trains, airplanes, airships and other transportation means.
  • the scanning means may be laser scanning means, e.g. including one or more laser range finders.
  • Laser range finders can be defined as a device which uses a laser beam to determine the distance to an object.
  • the most common form of laser rangefinder operates on the time of flight principle by sending a laser pulse in a narrow beam towards the object and measuring the time taken by the pulse to be reflected off the target and returned to the sender.
  • the frontier plane substantially coincides with the mooring plane or edge of a harbour quay, arranged for mooring one or more ships.
  • the detection means include one or more remotely controllable image cameras and the display means being arranged for displaying images made by the relevant image cameras.
  • the control means may be arranged to direct and/or focus at least one of said one or more remotely controllable image cameras towards the object detected by the scanning means in order to display at the display means one or more images of the detected object made by the relevant cameras.
  • the detection means may include one or more sensors arranged for detecting the presence of any moored ship at the harbour quay and for reporting such presence to the control means and/or display means. It is preferred then that the control means are arranged to restrict the making and/or displaying of camera images to areas where the presence of a moored ship at the harbour quay has been detected by said one or more sensors.
  • the present invention also provides a method for monitoring a frontier between two areas, the method comprising the steps of:
  • the step of selecting may be embodied by a software program product which is preferably provided on a data carrier such as a DVD.
  • a data carrier such as a DVD.
  • an intangible software program product downloadable from a remote server such as an Internet server, may be provided.
  • Figure 1 shows a harbour area including a quay 1 where two (foreign) ships 2 have been moored.
  • a harbour area including a quay 1 where two (foreign) ships 2 have been moored.
  • two (foreign) ships 2 have been moored.
  • the use of fences or other physic separation means at that frontier is not easy of feasible in practice. For that reason the novel system according to the invention for monitoring such a frontier can be applied.
  • the system comprises detection means, control means 3 and display means 4.
  • the control means which preferably comprise a microprocessor and/or a computer, are connected preferably wirelessly (although wired connections are also possible) to the detection means and the display means.
  • the detection means include scanning means 5 arranged for scanning a mainly vertical frontier plane 6 mainly coinciding with the frontier 7 between the areas 1 and 2.
  • the scanning means 5 are arranged for detecting any object and/or person 8 present in or crossing that frontier plane 6 and for reporting such detections to the control means 3 and/or display means 4.
  • the scanning means 5 may be laser (based) scanning means, e. g. including one or more laser range finders 5.
  • the frontier plane 6 mainly coincides with the mooring plane or edge 7 of the harbour quay 1 arranged for mooring ships 2.
  • the detection means include remotely controllable image cameras 9, e. g. surveillance dome cameras.
  • the display means 4 include one or more image/video monitors arranged for displaying images made by the image cameras 9.
  • the control means 3 are arranged to direct and/or focus the cameras 9 towards the object 8 detected by the scanning means 5 in order to display images of the detected object 8 made by the relevant cameras 9.
  • the system includes (e. g. ultrasonic) sensors 11 arranged for detecting the presence of any moored ship 2 at the harbour quay (edge) 7 and for reporting such presence to the control means 3 and/or display means 4.
  • the control means 3 are arranged to restrict the making and/or displaying of camera images 9 to areas where the presence of a moored ship 2 at the harbour quay has been detected by the sensors 11.
  • control means 3 comprise sensor fusion means for combining and/or analyzing the various sensor output signals.
  • control means 3 may comprise camera control means for controlling the cameras 9 and/or display control means for controlling the display means 4.
  • the sensor fusion means can be arranged - as indicated above - to select only relevant detections, i.e. crossings of the detection plane 6 within an areas where the sensors 11 detect the presence of a moored ship 2.
  • the sensor fusion means, and hence the control means may be arranged for outputting only such relevant detections to the camera control means, which are enabled to - possibly under control of the watchman. Non-relevant detections - e.g. due to the presence of fishermen etc.
  • control means are configured for using the second detection data to select, from the first detection data, detection data corresponding to a section of the frontier plane where a transportation means (such as a ship 2) is present, such that the display means display only selected detection data pertaining to relevant sections of the frontier.
  • the display means 4 are arranged to enable watchmen etc. to inspect/monitor remotely the relevant quay areas (of moored ships).
  • the display means 4 may include (additional) interface means, enabling the user (watchman) to input (e.g. via keyboard, touch screen, mouse) his/her information need, and/or serving as an interface to a further (computer) system like e.g. a content management system, which may be arranged to store/process camera images.
  • control means 3 may be implemented as a distributed processor/computer network.
