Infinite Realities discuss their improved system for producing highly realistic human 3D scans which can even capture intimate details of skin:
Over the last 2 years we’ve been busy drilling down on our new capture
technique for scanning faces and busts of people. In the hope to try and
improve the scanning process on from Photogrammetry. Inspired by the
incredible research of Paul Debevec at USC ICT, Dr. Abhishek Dutta and William Smith based on the Photometric Scanning
process. Our solution has a few extra features to add to the process.
We use our own custom software application to generate normal maps,
specular separated and multi light reference information.
… IR’s scanning system can capture high resolution reference data for
use in game and visual effects pipelines. The sort of data produced is
perfect for real-time and offline rendering by comparing results in the
view-port directly to measured scan data. We can capture synchronized
RAW (.exr) multi-light data, non polarized and cross polarized from up
to 50x angles of a subject very quickly.We are able to synchronize over 50 DSLR’s capturing RAW data over multiple PC’s using USB 3.1, reliably.The system is using a custom built mixed spherical gradient
illumination lighting solution as well as separate flash heads. We can
capture all the necessary lighting directions, cross and non polarized
as well as hot flash shots for as many directions as required.
