Abstract
Systems and methods for calibrating deformable sensors are disclosed. In one embodiment, a method of calibrating a deformable sensor includes capturing image data of the deformable sensor using an external image sensor, wherein the deformable sensor comprises a deformable membrane defining an enclosure that is configured to be filled with a medium. The method further includes comparing the image data of the deformable sensor to a metric. When the image data does not satisfy the metric, the method includes adjusting a pressure within the enclosure.

A method of calibrating a deformable sensor, the method comprising:
- capturing image data of the deformable sensor using an external image sensor, wherein the deformable sensor comprises a deformable membrane defining an enclosure that is configured to be filled with a medium, and the deformable membrane comprises a filter layer on a surface of the deformable membrane configured to assist in detection of a deformation of the deformable membrane;
- comparing the image data of the deformable sensor to a metric to generate a similarity value defining a degree of a difference between the deformable membrane in the image data and a geometry of the deformable membrane corresponding to the metric;
- and
- adjusting a pressure within the enclosure based on the similarity value.
A system comprising:
- a deformable sensor comprising a deformable membrane defining an enclosure that is configured to be filled with a medium, and the deformable membrane comprises a filter layer on a surface of the deformable membrane configured to assist in detection of a deformation of the deformable membrane;
- an external image sensor external to the deformable sensor;
- a processor;
- and
- a non-transitory computer readable medium storing instructions that, when executed by the processor, causes the processor to:
- capture image data of the deformable sensor using the external image sensor;
- compare the image data of the deformable sensor to a metric to generate a similarity value defining a degree of a difference between the deformable membrane in the image data and a geometry of the deformable membrane corresponding to the metric;
- and
- adjust a pressure within the enclosure based on the similarity value.
