High-quality 3D imaging with Commodity Devices

High-quality 3D imaging with Commodity Devices

3D imaging methods accessible to a broad audience

This body of work introduces a series of systems that only require commodity devices such as screens, (web-) cameras, low-end tablets or mobile phones to capture high-quality 3D data: The developed “Mobile Multiview Deflectometry” system exploits screen and front camera of mobile devices for deflectometry-based measurements. It works without the need for a calibration and is optimized for specular surfaces such as stained glass artworks. To compensate for the small screen, a multi-view registration technique is applied so that large surfaces can be densely reconstructed in their entirety. The “SkinScan” sensor principle uses the same hardware components but exploits photometric stereo algorithms for the measurement of matte object surfaces such as human skin.

Applications: The project is a first step towards a universal self-calibrating measurement procedure usable by a broad audience with little to no technical imaging experience. The introduced sensor principles have great potential for telemedicine or medical treatment/diagnosis in developing countries.
