To provide a fishing vessel activity estimation device and a fishing vessel activity estimation program which can obtain activity discrimination result data expressing discrimination results whether a fishing vessel is under movement or under an operation in time series.SOLUTION: A vessel speed feature vector data acquisition unit 225 acquires vessel speed feature vector data SVF including vessel speed detection value data SV representing a time series of speed of a fishing vessel and vessel speed variation data SVb representing a time series of variation of the speed of the fishing vessel. An activity estimation unit 241 performs activity discrimination processing of discriminating whether the fishing vessel is under movement or an under an operation by using the vessel speed feature vector data SVF, and outputs activity discrimination result data AD representing results of the activity discrimination processing in time series.SELECTED DRAWING: Figure 15
【課題】漁船が移動中であるか操業中であるかの判別結果を時系列で表した活動判別結果データを得ることができる漁船活動推定装置及び漁船活動推定プログラムを提供する。【解決手段】船速特徴ベクトルデータ取得部225は、漁船の速度の時系列を表す船速検出値データSVと、漁船の速度のばらつきの時系列を表す船速ばらつきデータSVbとを含む船速特徴ベクトルデータSVFを取得する。活動推定部241は、船速特徴ベクトルデータSVFを用いて、漁船が移動中であるか操業中であるかを判別する活動判別処理を行い、活動判別処理の結果を時系列で表した活動判別結果データADを出力する。【選択図】図15
