Finally, a formal analysis to evaluate the performance of an omnistereoscopic camera taking into account a model for the human binocular vision is still waiting. Furthermore, there is a need for a model to represent the binocular and omnidirectional viewing of the scene. However promising, the capabilities of these multicamera techniques have not been properly justified by theoretical models of omnistereoscopic image formation. Despite this, some sequential strategies have inspired multicamera configurations that may be suitable for the task. Consequently, sequential acquisition strategies to create stereoscopic panoramas are inadequate for this problem. The camera must sample the necessary visual information omnidirectionally from a chosen reference viewpoint in space, and it has to do this in a single snapshot to account for scene dynamics. In order to satisfy the constraints of the problem as defined, we need a panoramic camera capable of acquiring all of the scene’s necessary visual information to reconstruct stereoscopic views in arbitrary directions. A few cameras can capture omnistereoscopic visual information in a single snapshot, but some of these cameras are unsuitable to produce omnistereoscopic views suitable for human binocular vision, while the capabilities of other potentially suitable cameras have not been formally demonstrated.

These two views must correspond to the views from the left and right eyes of a human viewer since they should be able to stimulate the mechanism of human binocular vision, reproducing a credible and consistent perception of depth. Most practical scenarios are intrinsically dynamic, and hence a practical omnistereoscopic camera should be able to provide the means to render (in real time or off-line) two views of the scene with horizontal parallax, in any arbitrary gazing direction with respect to the capture viewpoint. Special distinction has to be made between dynamic and static scenes. However, a camera capable of capturing stereoscopic panoramas of dynamic scenes in a single snapshot is a problem still open for contributions since most of the omnistereoscopic acquisition strategies are constrained to static scenes. The improved realism attained by using real-world omnidirectional pictures instead of synthetic three-dimensional (3-D) models is evident. In recent years, the availability of single-snapshot panoramic cameras has enabled a variety of immersive applications. A comparative study of the different cameras and methods to create stereoscopic panoramas of a scene, highlighting those that can be used for the real-time acquisition of imagery and video, is presented.

Potential uses for a stereo panoramic camera with such characteristics are free-viewpoint 3-D TV and image-based stereoscopic telepresence, among others. Hence, there is a need for a panoramic camera to enable the consistent and correct stereoscopic rendering of the scene in every direction. Alternatively, sequential acquisition methods, such as rotating image sensors, can produce remarkable stereoscopic panoramas, but they are unable to capture real-time events. Even though some of these methods can estimate omnidirectional depth in real time, they were not conceived to render panoramic images for binocular human viewing. Several methods to produce stereoscopic panoramas have been proposed in the last decade, some of which were conceived in the realm of robot navigation and three-dimensional (3-D) structure acquisition. However, capturing omnistereoscopic snapshots and videos of dynamic scenes is still an open problem. Different camera configurations to capture panoramic images and videos are commercially available today.
