Abstract
A deformation sensor disclosed herein may include a plurality of three-dimensional (3D) objects arranged on a deformable membrane and an optical sensor. Each 3D object includes two or more colored parts. The colored parts include two or more colors. At least one pair of neighbor colored parts includes different colors. The optical sensor is configured to image the 3D objects to determine a deformation of the deformable membrane based on a color distribution of the 3D objects.
Claims20
A deformation sensor comprising:
- a plurality of three-dimensional (3D) objects arranged on a deformable membrane, each 3D object comprising two or more colored parts, wherein the colored parts comprise two or more colors, and at least one pair of neighbor colored parts comprises different colors;
- and
- an optical sensor configured to image the 3D objects to determine a deformation of the deformable membrane based on a color distribution of the 3D objects.
A method for measuring a deformation using a deformation sensor comprising:
- imaging, using an optical sensor, a color distribution of a plurality of three dimensional (3D) objects disposed on a deformable membrane, each 3D object comprising two or more colored parts, wherein:
- the colored parts comprise two or more colors,
- at least one pair of neighbor colored parts comprises different colors, and
- the color distribution comprises one or more captured colors for each 3D object;
- generating real-time proximity depths of the 3D objects based on the color distribution of the 3D objects;
- and
- determining a deformation of the deformable membrane at least partially based on the real-time proximity depths and historical proximity depths of the 3D objects.
