Abstract: A virtual reality immersion system provides a head mounted display that contains a video camera and a video display. A plurality of target markers are distributed within a virtual environment room where each target is distinct from all other targets in the virtual environment room and distinct from rotated versions of itself. An automatic calibration program selects pair of targets from an image from the video camera. The selected pairs of targets are identified and the position of each target is calculated relative to the camera and relative to each other. The positions of each target pair are added to a list of relative target transforms. Video signals are processed to calculate the position of targets detected in each frame image using the relative target transforms and the effects of viewing angles are detected and a higher weight is given to targets that are detected at more reliable angles. The invention dynamically streams 3D content to the user through the video display.

Abstract: An image-based rendering system and method is disclosed for displaying 3D images of a subject (e.g. an object or scene). A compressed image file having multiple corrected and calibrated images of a subject from various viewpoints from along a trajectory about the subject is generated. Prior to selected viewpoints of the object being displayed, the compressed image file is at least partially transcoded to a randomly accessible format such that individual or multiple images may be extracted for immediate display or further processing. One or more final extracted images are optionally used in interpolation, morphing, or stitching algorithms before display to a viewer.

Abstract: A 3-D Instant Replay system is disclosed for the capture, adjustment, and generation substantially in real time of complex 3-D or other video effects. A camera array is configured about a desired scene for effect generation. Image information from multiple cameras is sent instantaneously and simultaneously to a capture system. Multiple capture devices may be used together in the capture system to capture video information from a large number of cameras. Once inside each capture device, image data is made available in the memory element of the capture system for generation of realtime effects. A host system, connected via high speed networking elements to the capture system, selects relevant portions of available image data from the capture system (or each capture device) based on preset criteria or user input.

Abstract: In one aspect of the present invention, the inventive system is capable of inserting video images of human being, animals or other living beings or life forms, and any clothing or objects that they bring with them, into a virtual environment. It is possible for others participating in the environment to see that person as they currently look, in real-time, and from any viewpoint. In another aspect of the present invention, the inventive system that was developed is capable of capturing and saving information about a real object or group of interacting objects (i.e., non-life forms). These objects can then be inserted into a virtual environment at a later time. It is possible for participants in the environment to see the (possibly moving) objects from any viewpoint, exactly as they would appear in real life. Since the system is completely modular, multiple objects can be combined to produce a composite scene. The object can be a human being performing some rote action if desired.
