Evasion target discrimination method for estimating the presence of obstacles not equipped with AIS, estimation result display device, avoidance target discrimination information sharing method, avoidance target discrimination program, and avoidance target discrimination usage method

摘要

PROBLEM TO BE SOLVED: To estimate the existence of an AIS-free obstacle even when the AIS-free obstacle exists in a place not reflected by a radar due to topographical restrictions or the like. To provide a target discrimination method, an estimation result display device, a avoidance target discrimination information sharing method, a avoidance target discrimination program, and a avoidance target discrimination utilization method. SOLUTION: The AIS information receiving process S1 for receiving the AIS information of another ship 20 existing around the own ship 10 and the track information based on the time series data of the AIS information accumulated in the AIS information are used to change the needle of the other ship 20. The determination result and AIS information of the avoidance motion determination process S2 and the avoidance motion determination process S2 for determining whether or not the change of course is an avoidance operation for avoiding the obstacle 30 that hinders the traveling of the other ship 20. Therefore, it is provided with an avoidance target determination process S3 for determining whether or not the obstacle 30 is an obstacle not equipped with AIS. [Selection diagram] Fig. 1
