To provide a sailing object discrimination method for estimating the object's existence and position with high accuracy even when an AIS non loaded obstacle exists in a place not showing on a radar due to geological restrictions, etc, an estimation result display device, a sailing object discrimination information sharing method, a sailing object discrimination program, and a sailing object discrimination use method.SOLUTION: A sailing object discrimination method includes: an AIS information receiving process S1 for receiving AIS information of another vessel 20 exists in the periphery of own vessel 10; a sailing action discrimination process S2 for determining a change of course of the other vessel 20 from track information based on time sequence data of the AIS information accumulating the AIS information and determining whether or not it is a sailing action to evade an obstacle 30 which is to be an obstacle in traveling of the other vessel 20; and a sailing object discrimination process S3 for determining whether or not an obstacle 30 is an AIS non loaded obstacle from the determination result of the sailing action discrimination process S2 and the AIS information.SELECTED DRAWING: Figure 1
【課題】AIS非搭載障害物が、地形的な制約等によりレーダーに映らない場所に存在する場合であっても、その存在や場所を精度よく推定するAIS非搭載障害物の存在を推定する避航対象判別方法、推定結果表示装置、避航対象判別情報共有方法、避航対象判別プログラム、及び避航対象判別利用方法を提供すること。【解決手段】自船10の周辺に存在する他船20のAIS情報を受信するAIS情報受信過程S1と、AIS情報を蓄積したAIS情報の時系列データに基づいた航跡情報から他船20の変針を判断し、変針が他船20の走行の障害となる障害物30を避けるための避航動作であるか否かを判断する避航動作判別過程S2と、避航動作判別過程S2の判断結果とAIS情報から、障害物30がAIS非搭載障害物であるか否かを判断する避航対象判別過程S3とを備える。【選択図】図1
