3D imaging with LEDs and smartphone points to simpler machine vision

University of Strathclyde project creates images without complex synchronizing of camera and lighting.
Monkey seen: imaging with overhead LEDs
An approach to 3D imaging employing conventional LED room lighting and a smartphone could led to more straightforward visualization methods for industrial or security applications.
The new method has been developed by a team at the University of Strathclyde Institute of Photonics and Bristol Robotics Laboratory, in work supported by the UK EPSRC QuantIC research program. It represents an enhancement of photometric stereo (PS) imaging, in which a 3D image is built up from one fixed camera perspective and different illumination directions.
