To provide a standard route generation device for generating a standard route region on the basis of the tracks of ships in the past, and a ship monitoring device that uses the standard route region.SOLUTION: A standard route generation device 1 comprises: a storage unit 10 for storing a map 3 which is divided into a plurality of cells 2 by a grid, position information that indicates the tracks 4 of a plurality of ships, and voyage information; a route cell setting unit for setting on the basis of position information a plurality of route cells 20 that represent a standard route and include a first route cell 21 and a second route cell 22; a line calculation unit 631 for calculating, on the basis of the position information and voyage information, a line L1 that links the first route cell 21 and second route cell 22 among the tracks 4 passing through both of the first route cell 21 and second route cell 22 in the same voyage of the same ship; a route interpolation unit 632 for changing a cell that is not the route cell 20 to a route cell 20, on the basis of the line L1; and a standard route region generation unit 67 for generating a standard route region on the basis of the route cell 20.SELECTED DRAWING: Figure 1

    【課題】過去の船舶の航跡に基づき標準航路領域を生成する標準航路生成装置および標準航路領域を用いる船舶監視装置を提供する。【解決手段】標準航路生成装置1は、グリッドで複数のセル2に分割された地図3と複数の船の航跡4を示す位置情報と航海情報とを記憶する記憶部10と、位置情報に基づいて、標準航路を表し且つ第1航路セル21及び第2航路セル22を含む複数の航路セル20を設定する航路セル設定部と、位置情報と航海情報とに基づいて、同一船舶の同一航海上における第1航路セル21と第2航路セル22の両方を通る航跡4のうち、第1航路セル21と第2航路セル22とを結ぶラインL1を算出するライン算出部631と、ラインL1に基づいて、航路セル20でないセルを航路セル20に変更する航路補間部632と、航路セル20に基づいて、標準航路領域を生成する標準航路領域生成部67と、を有する。【選択図】図1
