Three-Dimensional Shape Capture Sheet Using Distributed Triaxial Accelerometers

In this paper, we propose a novel sensing device named "3-dimensional capture sheet (3DCS)". The cloth-like sheet measures its own 3D configuration. It consists of a lattice structure inside of the sheet, and each link of the structure has a triaxial accelerometer. The roll and pitch angles of the link are calculated from the gravity vector measured with the accelerometer. Furthermore, the relative yaw angle is also determined by using constraints originating from the lattice structure. The whole shape of the sheet is reconstructed by combining the obtained postures of all the links.
