Aplicação do GelSight para obtenção de uma imagem 3D em alta resolução

By combining a physical interface with intelligent computer vision algorithms, researchers at the Department of Brain and Cognitive Sciences, Massachusetts Institute of Technology (MIT), USA, have created a portable imaging system that can achieve resolutions microscopic, so far only possible with equipment large and expensive laboratory.

The GelSight uses multiple cameras to measure the deformation of rubber, which produces 3D models of an object that can be manipulated on the computer screen to examine from various angles.

The device, called GelSight, will have applications in medicine, forensics and biometrics. See the video on the how the device.

The creators of the device, Dorothy Wilson and Edward Adelson, already in negotiations with a leading aerospace and various industrial equipment manufacturers interested? GelSight in use to verify the integrity of their products. The technology has also attracted the interest of forensic experts, as this would be a cheap and efficient way to identify fingerprints. Moreover, it could also have applications in medicine, for example, dermatology and biometrics.

The device arose from a project to create sensors for robots, giving them tactile sensitivities. Adelson and Johnson quickly realized that the system captured the land in much higher resolution than these sensors actually need.

The graphics researcher Paul Debevec, whose doctoral thesis was support for special effects in the movie "The Matrix", is particularly interested? In GelSight will reveal about the surface characteristics of human skin. "This kind of visualization will bring much more accurate simulations. He said.
