The Stereoscopic Analyzer (STAN) combines realtime image analysis with intelligent visualization tools and intuitive graphical user interfaces to assist cameramen and production staff in shooting the right stereo content for 3D post-production and 3D live events.

Supported by our partner: KUK Filmproduction GmbH

STAN captures and analyses stereo images in real-time. Corresponding feature points in the scene are matched automatically to determine the given disparity range, and to compute stereo calibration data. Using actuators, the stereo baseline and other mechanical parameters of the stereo rig can be adjusted automatically so that the specified disparity range is not exceeded and the stereo images are almost rectified. Furthermore, residual distortions in color and stereo geometry can be corrected using real-time color matching and rectification. STAN uses a touch screen for intuitive user interaction. Various viewing tools like crop/opacity overlay, side-by-side, checkerboard or anaglyphic stereo can be selected to analyze the stereo quality while other tools like RGB parade, signal waveforms or color histograms assist control of color quality. Real-time estimation of dense pixelby-pixel disparity maps can be used to visualize the depth structure of the scene. Basic stereo parameters like convergence planes can be adjusted manually and the results watched simultaneously on the screen. Related shift-cropscale processing is done on-the-fly.
