Paper Abstract

Today, 3D viewing devices still need qualitative content; up to now, there is no real 3D video shooting system specifically designed to ensure a qualitative 3D experience on some pre-chosen 3D display. A fundamental element of multiscopic image production is the geometrical analysis of shooting and viewing conditions in order to obtain a qualitative 3D perception experience. Many autostereoscopic camera systems are proposed but none is designed with control of possible depth distortions in mind. This article introduces a patented autostereoscopic camera design scheme based upon this distortion control. Thanks to our scientific know-how, we based our work on the link between the shooting and rendering geometries, which enables to control the distortion of the perceived depth. Thus this design scheme provides camera systems producing qualitative 3D content complying with any pre-chosen distortion when rendered on any specific autostereoscopic display. Thanks to our technological expertise, we use this design scheme to product pre-industrial camera systems devoted to 3D live or pre-recorded shooting. These systems are compact, lightweight, easy to deploy and rather adaptable to other conditions (3D displays, depth distortion). We will introduce the associated software, which allows to control our 3D cameras and to display in real-time on the autostereoscopic display formerly specified. According to numerous spectators, both naive and expert, the 3D perception is really qualitative.
