CPS(Cyber-Physical Systems)には対象によって多様な実現形が存在すると考えられるが,サイバーとしてCAE(Computer-Aided Engineering)シミュレーション,フィジカルとして対応する計測データを考えた場合,それらの融合はそれぞれの不確かさを考慮するため確率的に(すなわちベイズ的に)行うのがよさそうである.数値シミュレーションと計測データを使ってベイズ推定を実現するデータ同化は,シミュレーションモデルの不確かな要因(初期・境界条件,モデルパラメータ等)を観測値により統計的に修正する方法である1).このようなデータ同化によってサイバーとフィジカルの同期(Cyber-Physical Synchronization)が期待される.本稿では特に映像を通してサイバーとフィジカルを連携させた例を紹介する.
