360 Degree Imaging Technology

The Omnicam (shown in Figure 1) is an imaging system, developed in the CAVE lab, used to capture seamless 360-degree photographs.  The system, called OneShot 360, is a commercial package offered by RemoteReality. The system will “un-distort” these 360-degree images to proper perspective images and allow a user to navigate throughout the entire 360-degree space (left, right; up, down; zoom in and out) with a mouse as if the user were present in the scene. If a user wishes to capture a complete 360x360-degree scene, he/she must use RemoteReality's OneShot360 Plus package. In this case, a photographer must capture four images with the OneShot 360 camera to render a single 360x360 degree scene; the four images are taken at 90 degree intervals.  These images are then imported to the OneShot Plus software, which stiches the four images into one image. An example of an image that results from this system is shown in Figure 2.
