Abstract
[Object] To provide a sheet-like structure capable of highly accurately estimating a sheet-like shape. [Solving Means] A sheet-like structure includes a sheet-like member and a plurality of detection sensors. The sheet-like member extends along an in-plane direction orthogonal to a thickness direction and receives light incident on the sheet-like member. The plurality of detection sensors are dispersedly arranged on the sheet-like member along the in-plane direction and are for detecting an incident angle of the light with respect to the sheet-like member at each arrangement position of the plurality of detection sensors.
Claims6
A shape estimation method, comprising:
- setting a reference plane of a sheet-like structure on which light is incident, wherein the sheet-like structure is a bendable structure;
- acquiring first information regarding a reference incident direction of the light with respect to the reference plane;
- acquiring second information regarding local incident angles of the light with respect to the sheet-like structure at a plurality of detection positions in two or more states in which the reference incident directions are different from one another, the plurality of detection positions being dispersedly arranged on the sheet-like structure, wherein the second information is a set of data indicating the local incident angle for each detection position of the plurality of detection positions;
- and
- estimating a three-dimensional shape of the sheet-like structure on a basis of the first information and the second information in the two or more states.
