Patent 10574944 was granted and assigned to GelSight on February, 2020 by the United States Patent and Trademark Office.
Continuous measurement of surfaces larger than a sensor is facilitated by the use of a sensor matrix of a clear elastomer and a reflective surface that scrolls, rolls, or otherwise moves over a target surface. A variety of web materials, camera configurations, and handling systems are described to achieve continuous three-dimensional measurement in this context.
