We aim to produce a wide field-of view large autostereoscopic display for multiple viewers based on a 1D retroreflective screen and overheard microprojectors. The 1D retroreflective screen consists of retroreflector, anisotropic diffuser, and embedded fiber-optic array with optical sensors. Microprojectors modified with wide angle converter lenses are mounted unobtrusively over each viewing location. Each projector’s structured lighting is detected by the screen’s sensor array for calibration. Pin-cushion distortion correction, rectification and cross-talk reduction are implemented for proper stereo fusion. We examine common viewing scenarios of single viewer autostereoscopic projection, multiprojector automultiscopic projection, side by side multiviewer common and independent autostereoscopic projection, and frontback autostereoscopic projection.
