Integration of stereoscopic laser-based geometry into 3D video using DLP Link synchronisation

ABSTRACT Stereoscopic video projection using active shuatter glasses is a mature technology employed in multi-person immersive virtual reality environments such as CAVE systems. On the other hand, non-stereoscopic laser projectors are popular in the entertainment industry because they can display graphics at greater distances and cover larger areas. However, stereoscopic-capable laser-based vector graphics could enhance video-based immersive 3D experiences, due to their unique visual characteristics including extremely high contrast and arbitrarily extended gamut through the use of multiple laser sources. Their virtually infinite depth of field also allows for easy installation compared with video projectors, regardless of the size of the augmented space. In this work, we demonstrate a system integrating 3D laser-based vector graphics into a dynamic scene generated by a conventional stereoscopic video projection system.
