Gravity-based 3DCS

>> BACK TO TOP PAGE

Fabric is a material very close to us, and its motion is very interesting.
In order to measure the motion, we develop a cloth-like sheet that measures its own 3D configuration.
With the sheet, you can measure the shape and size of an object with ease.


Fig.1 Illustration of 3DCS
There is a lattice structure in the 3DCS, and a triaxial accelerometer is attached on each link.
The whole configuration is estimated using the gravity vector measured by accelerometers.
