【発明の詳細な説明】
産業上の利用分野
本発明は、船舶の航行援助装置として用いられる海図情
報処理装置に関するものである。DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a nautical chart information processing device used as a navigational aid device for ships.
従来技術
これまで、海岸線、等探線、航路標識などの極めて限定
された範囲の海図情報とレーダ情報とを重畳して航行に
利用する重畳表示装置は種々提供されている。BACKGROUND OF THE INVENTION Until now, various superimposition display devices have been provided that superimpose nautical chart information and radar information in extremely limited ranges, such as coastlines, isolines, and navigational markers, for use in navigation.
この発明が解決すべき問題点
しかしながら、前記の様な従来型の装置では沿岸、港内
航行に必要な詳細な海図情報（例えば水深、海流、潮流
、沈船、漁礁、港区界、指定錨地底質他）、は表示され
ず、こうした限定情報では大洋航行はできても様々な航
行障害の予想される沿岸、及び港内航行は難しかった。Problems to be Solved by this Invention However, conventional devices such as those described above do not provide detailed nautical chart information necessary for coastal and port navigation (e.g., water depth, ocean currents, currents, shipwrecks, fishing reefs, port area boundaries, designated anchors, subsurface sediments, etc.). etc.) were not displayed, and although ocean navigation was possible with this limited information, it was difficult to navigate coastal areas and in ports where various navigational obstacles were expected.
また、従来装置では表示する情報はすべてディジタル化
してビデオＲＡＭＫＣＰＵを介して書き込む方法を採用
している。このため、沿岸及び港内航行に必要な海図情
報をすべて表示するには海図の全情報をディジタル化す
る必要があるため膨大な情報量となり、コンピュータ・
システムのメインメモリや処理時間及びこれらの情報を
ストアしておく記憶装置の容量が実用的な範囲を超えて
しまうという問題があった。Furthermore, in the conventional device, all the information to be displayed is digitized and written via the video RAM KCPU. Therefore, in order to display all the nautical chart information necessary for coastal and port navigation, it is necessary to digitize all the nautical chart information, resulting in a huge amount of information, which requires computer processing.
There was a problem in that the main memory of the system, the processing time, and the capacity of the storage device for storing this information exceeded the practical range.
さらに、従来型の装置ではディジタル海図とレーダ映像
とのマツチング処理を行わずジャイロによる方位信号と
ログによる船速信号で自船の移動を推測計算して海図上
における自船位置をプロットするか、ある測定誤差分布
を含む電波航法装置により自船位置をプロットしている
ため海図映像とレーダ映像とにズレが生ずるのを防げな
かった。Furthermore, conventional equipment does not perform matching processing between digital nautical charts and radar images, but estimates and calculates the own ship's movement using the azimuth signal from the gyro and ship speed signal from the log, and plots the own ship's position on the chart. Because the ship's position is plotted using a radio navigation device that includes a certain measurement error distribution, it was not possible to prevent discrepancies between the chart image and the radar image.
そこでこの発明は、前記の様な従来の海図情報とレーダ
情報の重畳表示装置における不都合な点を改善して海図
の全情報とレーダによる他船及び陸地情報を表示装置に
重畳表示することにより、周囲状況を一目瞭然で判断で
きる形で航海士に提供し、大洋航行のみならず沿岸、港
内航行における座礁や衝突の遊行操船あるいは投錨停泊
海域選定のアシストを行ない得る海図情報表示装置を提
供することを目的とする。Therefore, the present invention improves the disadvantages of the conventional superimposed display device of nautical chart information and radar information as described above, and superimposes and displays all the information of the nautical chart and information of other ships and land by radar on the display device. It is an object of the present invention to provide a nautical chart information display device that can provide a navigator with information on the surrounding situation in a form that allows him to clearly judge the situation at a glance, and can assist in maneuvering a ship in case of grounding or collision in not only ocean navigation, but also coastal and port navigation, as well as the selection of anchorage areas. purpose.
