PROBLEM TO BE SOLVED: To provide a device that can freely estimate a shape of any place in a human body and other object of interest.SOLUTION: A shape estimation device is characterized by including a curvature information acquisition unit for acquiring curvature information of each curvature sensor of a sheet configured by a base material provided with the curvature sensor every predetermined interval, and a shape estimation unit for estimating a shape of the base material based on the curvature information. The shape estimation unit estimates the shape of clothes based on the curvature information of each curvature sensor of clothes made by using the sheet, and detects the motion of an object wearing the clothes based on the shape of the clothes.SELECTED DRAWING: Figure 1【課題】人体やその他の対象物の任意の箇所の形状を自由に推定することできる装置を提供する。【解決手段】所定の間隔毎に曲率センサを設けた基材により構成されたシートの曲率センサそれぞれの曲率情報を取得する曲率情報取得部と、曲率情報に基づいて基材の形状を推定する形状推定部と、を備えることを特徴とする。形状推定部は、シートを用いて製造された衣服の各曲率センサの曲率情報に基づいて衣服の形状を推定し、衣服の形状に基づいて前記衣服を纏った対象の動作を検出する【選択図】図１
