Title:
CLASSIFICATION DEVICE AND CLASSIFICATION METHOD
Document Type and Number:
WIPO Patent Application WO/2015/107805
Kind Code:
A1
Abstract:
This classification device comprises a processor which executes a program and a memory which stores the program which the processor executes. The processor executes: an acquisition process which acquires a string of time series data which specifies locations and speeds in time series of a ship; a grouping process which, on the basis of the time difference and/or the speed difference of two continuous instances of the time series data among the string of time series data which is acquired by the acquisition process, groups the string of time series data into a first time series data group up to preceding time series data among the two instances of time series data, and a second time series data group from successive time series data among the two instances of time series data, and sets each to navigation data; a determination process which determines the navigation type of the navigation data on the basis of the speed of the time series data group which is included in the navigation data which is grouped by the grouping process; and an output process which outputs the result of the determination which is determined by the determination process.
