STAN – Steroscopic Analyzer

Perfect Stereo 3D Production in Real-time

The Stereoscopic Analyzer STAN is a system for production of perfect stereo 3D. STAN combines real-time image analysis with intelligent automated tools. An intuitive graphical user interface assists camera operators and production staff in shooting technically correct stereo for all 3D genres including live events.

  • Real-time correction of geometric and colorimetric distortions 
  • Visualization tool for evaluating stereo quality
  • Adaptation of disparity range to captured scene with respect to available depth budget
  • Automatic control of optimal interaxial distance
  • Adaptation of convergence plane using horizontal image translation (HIT) in real-time for live broadcast

Technical Background

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.
