Optimized 3D Stereo Analysis with STAN

Fraunhofer HHI partners with Silicon Imaging

The Fraunhofer Heinrich Hertz Institute HHI and the American company Silicon Imaging have joined forces with a view to streamlining production of 3D stereo acquisition and recording and making it more efficient. In pursuit of this end, STAN, the stereoscopic analyzer assistance system developed by Fraunhofer HHI has been integrated as a plug-in in Silicon Imaging's SI-3D S.M.A.R.T system. S.M.A.R.T stands for Stereo Monitoring, Analysis, Recording, and Transmission.

The stereoscopic analyzer assistance system – known as STAN for short – supports camera operators, stereographers and the whole production team in the production of 3D recording. Parameters which are vital in determining the quality of the stereo – like color matching, stereo geometry or the positioning of the two cameras – can vary from scene to scene depending on shot motif and content, near and far objects, convergence planes and depths of focus. One of the things STAN does is ensure that the parameters calculated for the shot are directly fed to the two cameras so that incorrect settings can be identified and rectified either automatically or by hand, depending on what kind of stereo recording system is being used.

The award-winning SI-3D system is a user-friendly platform for setting up 3D camera rigs with various kinds of equipment that features all the tools needed for production of 3D – from 4K through to HD. Integration of STAN into this system means that parameters vital for stereo quality – like color matching, stereo geometry or the positioning of the two cameras – can now be automatically analyzed, and if need be corrected, during actual shooting. The SI-3D S.M.A.R.T system also enables continuous wireless monitoring of the stereo recording with an iPad.

At NAB Fraunhofer HHI and Silicon Imaging are showcasing the SI-3D S.M.A.R.T system at the Fraunhofer stand C8444.
