The marine image 111 is received, and the outline line coordinate information extraction unit 120 extracts outline line coordinate information for a plurality of marine images.

また、前記電子海図格納部１３０は、図４に示すように、複数の外郭線座標情報による外郭線（３０ａ、３０ａ−１、３０ａ−２）（２０ａ、２０ａ−１、２０ａ−２）が表示された電子海図１４１を生成して格納する。   Further, as shown in FIG. 4, the electronic chart storage unit 130 displays outline lines (30a, 30a-1, 30a-2) (20a, 20a-1, 20a-2) based on a plurality of outline coordinate information. The generated electronic chart 141 is generated and stored.

しかしながら、前記電子海図格納部１３０は、同一な映像客体に対して時間によって変化する互いに異なる外郭線がそれぞれ表示された電子海図を格納することもできる。   However, the electronic chart storage unit 130 may store electronic charts in which different outlines that change with time are displayed for the same video object.

前記電子海図出力部１４０は、前記映像客体２０、３０の外郭線２０ａ、３０ａが表示された電子海図１４１を出力する。   The electronic chart output unit 140 outputs an electronic chart 141 on which outlines 20a and 30a of the video objects 20 and 30 are displayed.

また、前記電子海図出力部１４０は、例えばディスプレイ裝置か、プリンタ裝置である。   The electronic chart output unit 140 is, for example, a display rack or a printer rack.

また、前記電子海図出力部１４０は、時間の流れによって変化する前記映像客体２０、３０の外郭線が、様々な方法により前記電子海図上に表示されるように出力できる。   In addition, the electronic chart output unit 140 may output the contour lines of the video objects 20 and 30 that change with the passage of time so as to be displayed on the electronic chart by various methods.

例えば、図４に示すように、前記電子海図出力部１４０は、前記映像客体２０、３０に対した複数の外郭線（３０ａ、３０ａ−１、３０ａ−２）（２０ａ、２０ａ−１、２０ａ−２）のうち、現在の日付および現在時刻の外郭線２０ａ、３０ａが他の外郭線（２０ａ−１、２０ａ−２）（３０ａ−１、３０ａ−２）と互いに区分されるように表示して電子海図１４１を出力できる。   For example, as shown in FIG. 4, the electronic chart output unit 140 may include a plurality of contour lines (30a, 30a-1, 30a-2) (20a, 20a-1, 20a-) for the video objects 20, 30. 2), the outlines 20a and 30a of the current date and current time are displayed so as to be separated from the other outlines (20a-1, 20a-2) (30a-1, 30a-2). An electronic chart 141 can be output.

例えば、前記複数の外郭線（３０ａ、３０ａ−１、３０ａ−２）（２０ａ、２０ａ−１、２０ａ−２）のうち、現在の日付および現在時刻の外郭線２０ａ、３０ａは、他の外郭線（２０ａ−１、２０ａ−２）（３０ａ−１、３０ａ−２）と色または太さなどが互いに異に表示することができる。   For example, among the plurality of contour lines (30a, 30a-1, 30a-2) (20a, 20a-1, 20a-2), the contour lines 20a, 30a of the current date and the current time are other contour lines. (20a-1, 20a-2) (30a-1, 30a-2) can be displayed different from each other in color or thickness.

しかしながら、前記電子海図出力部１４０は、前記外郭線（３０ａ、３０ａ−１、３０ａ−２）（２０ａ、２０ａ−１、２０ａ−２）の形状は同一に出力するが、それぞれの外郭線に日付、時刻、海水面の高さまたは潮時（ｔｉｄｅ ｔｉｍｅ）などに注釈をつけて互いに区分されるように出力できる。   However, the electronic chart output unit 140 outputs the contour lines (30a, 30a-1, 30a-2) (20a, 20a-1, 20a-2) in the same shape, but outputs the date to each contour line. , Time, sea level or tide time can be annotated and output to be separated from each other.

すなわち、前記電子海図出力部１４０は、潮汐の影響による、時間の流れによって変化する映像客体２０、３０の外郭線を航海者や航海管理者が一目で分かるという効果がある。   That is, the electronic chart output unit 140 has an effect that the navigator and the navigation manager can see at a glance the outline of the video objects 20 and 30 that change with the flow of time due to the influence of tides.

しかしながら、前記電子海図出力部１４０は、現在の日付および現在時刻に対応する１つの外郭線２０ａ、３０ａが表示された電子海図を出力できることは勿論、現在時刻に合うように更新された外郭線を有する電子海図を持続的に更新して出力することもできる。   However, the electronic chart output unit 140 can output an electronic chart on which one outline line 20a, 30a corresponding to the current date and the current time is displayed, as well as an outline line updated to match the current time. It is also possible to continuously update and output the electronic chart that it has.

前記電子海図送信部１５０は、前記外郭線座標情報、または前記電子海図１４１を陸地で船舶４０の安全航海を助ける安全運航支援システムの港湾管理システムや海上交通管理システムに伝送して航海管理者が安全に船舶の航海ができるように誘導する。   The electronic chart transmitting unit 150 transmits the outline coordinate information or the electronic chart 141 to a port management system or a marine traffic management system of a safe navigation support system that helps safe navigation of the ship 40 on land. Guide the ship so that it is safe to navigate.

また、前記電子海図送信部１５０は、前記外郭線座標情報または前記電子海図１４１を船舶４０に備えられるレーダ、電子海図情報表示装置、統合航法システムに更に伝送して航海者が船舶を安全に航海できるようにする。   Further, the electronic chart transmission unit 150 further transmits the outline coordinate information or the electronic chart 141 to a radar, an electronic chart information display device, and an integrated navigation system provided in the ship 40, so that the navigator can safely navigate the ship. It can be so.

しかしながら、本発明の電子海図更新システム１００は、前述したように前記港湾管理システム、前記海上交通管理システム、船舶のレーダ、電子海図情報表示装置または統合航法システムに一体型に統合されて備えることができることは勿論である。   However, as described above, the electronic chart update system 100 according to the present invention may be integrated with the port management system, the maritime traffic management system, the ship radar, the electronic chart information display device, or the integrated navigation system. Of course you can.
