Abstract
We propose a multi-viewer tracking integral imaging system for viewing angle and viewing zone improvement. In the tracking integral imaging system, the pickup angles in each elemental lens in the lens array are decided by the positions of viewers, which means the elemental image can be made for each viewer to provide wider viewing angle and larger viewing zone. Our tracking integral imaging system is implemented with an infrared camera and infrared light emitting diodes which can track the viewers' exact positions robustly. For multiple viewers to watch integrated three-dimensional images in the tracking integral imaging system, it is needed to formulate the relationship between the multiple viewers' positions and the elemental images. We analyzed the relationship and the conditions for the multiple viewers, and verified them by the implementation of two-viewer tracking integral imaging system.
Highlights
Many researches for three-dimensional (3D) display devices have been proceeding for more than a century
The virtual reality systems like CAVE (Cave Automatic Virtual Environment), Workbench, and Illusionhole use stereoscopic 3D display and apply the tracking technology to implement the motion parallax which is an important cue for spatial cognition [14,15,16]
The tracking integral imaging system needs a tracking method with fast response time enough to be applied in relatively large space since the elemental images should be made in real time while tracking viewers
Summary
Many researches for three-dimensional (3D) display devices have been proceeding for more than a century. The virtual reality systems like CAVE (Cave Automatic Virtual Environment), Workbench, and Illusionhole use stereoscopic 3D display and apply the tracking technology to implement the motion parallax which is an important cue for spatial cognition [14,15,16]. The tracking technology can be used to enhance viewing angle and viewing zone for one viewer as we proposed at a recent conference [19]. Viewer tracking enables elemental images to be generated corresponding with the viewer’s position dynamically. The wider viewing angle and the broader viewing zone can be implemented in the same integral imaging system. There is a problem when more than one viewer wants to see 3D images in the tracking integral imaging system. The analysis is used to interpret the system parameters of tracking integral imaging, and we implemented tracking integral imaging system for two viewers by the analysis
