Title (EN) NAUTICAL CHART IMAGE DISPLAY DEVICE
(FR) DISPOSITIF D’AFFICHAGE D’IMAGE DE CARTE MARINE
(JA) 海図画像表示装置
Abstract:
(EN) Provided is a nautical chart image display device wherein water depths of a water bottom that are obtained by measurement are allocated to respective meshes into which a nautical chart image is divided, the number of the meshes being smaller than the number of pixels in the nautical chart screen (S1), and a smoothing process is executed on the water depths of the water bottom allocated to the respective meshes (S2). An enlarging process is executed on the water depths of the water bottom allocated to the smoothed meshes, and the water depths of the water bottom are allocated to the respective pixels in the nautical chart image (S3). The resultant water depths of the water bottom are used to display, on the nautical chart screen, an image indicating the water depth of the water bottom at each position.
(FR) L'invention concerne un dispositif d'affichage d'image de carte marine dans lequel les profondeurs d'un fond d'eau qui sont obtenues par mesure sont attribuées à des mailles respectives dans lesquelles une image de carte marine est divisée, le nombre de mailles étant inférieur au nombre de pixels dans l'écran de la carte marine (S1), et un processus de lissage étant exécuté sur les profondeurs du fond d'eau attribuées aux mailles respectives (S2). Un processus d'agrandissement est exécuté sur les profondeurs du fond d'eau attribuées aux mailles lissées, puis les profondeurs du fond d'eau sont attribuées aux pixels respectifs dans l'image de la carte marine (S3). Les profondeurs obtenues du fond d'eau sont utilisées pour afficher, sur l'écran de la carte marine, une image indiquant la profondeur du fond d'eau à chaque position.
(JA) 海図画像に対して、その海図画面の画素数よりも少ない数で分割されたメッシュ毎に、そのメッシュに対して測定により得られた水底の水深を割り当て(S1)、各メッシュに割り当てられた水底の水深に対して平滑処理を行う(S2)。平滑処理された後のメッシュに割り当てられた水底の水深から拡大処理して、海図画像の各画素に対する水底の水深を割り当てる(S3)。その水底の水深を用いて、海図画面上に各位置における水底の水深を示す画像を表示する。
