摘要： Methods, systems, and computer readable media for shader lamps-based avatars of real and virtual people are disclosed. According to one method, shader lamps-based avatars of real and virtual objects are displayed on physical target objects. The method includes obtaining visual information of a source object and generating at least a first data set of pixels representing a texture image of the source object. At least one of a size, shape, position, and orientation of a 3D physical target object are determined. A set of coordinate data associated with various locations on the surface of the target object are also determined. The visual information is mapped to the physical target object. Mapping includes defining a relationship between the first and second sets of data, wherein each element of the first set is related to each element of the second set. The mapped visual information is displayed on the physical target object using a display module, such as one or more projectors located at various positions around the target object.

摘要： Methods, systems and computer products are provided for tracking objects within a scene using imperceptible structured light. The imperceptible structured light may be used in environments where humans work and therefore avoids disorienting observers. The structured light patterns are generated dynamically, allowing tracking without physical landmarks. Moreover, the occlusion of the generated landmarks is overcome by determining the position of objects using a determined camera position. The imperceptible structured light may be used in systems without tracking. The tracking may be used without imperceptible structured light.

摘要： Methods, systems, and computer readable media for generating autostereo three-dimensional views of a scene for a plurality of viewpoints are disclosed. According to one system, a display is configured to display images from plural different viewpoints using a barrier located in front of the display, where the barrier has a pseudo-random arrangement of light ports through which images on the display are viewable. A renderer coupled to the display simultaneously renders images from the different viewpoints such that pixels that should appear differently from the different viewpoints are displayed in a predetermined manner. The pseudo-random arrangement of the light ports in the barrier smoothes interference between the different viewpoints as perceived by viewers located at the different viewpoints.

摘要： Methods and systems for dynamic virtual convergence (218) and a video see through head mountable display (200) that uses dynamic virtual convergence are disclosed. A dynamic virtual convergence algorithm (218) includes sampling an image with two cameras. The cameras each have a field of view that is larger than a field of view of displays used to display images sampled by the cameras (210). A heuristic is used to estimate the gaze distance of the viewer. The display frustums are transformed so that they converge at the estimated gaze distance. The images sampled by the cameras (210) are then reprojected into the transformed display frustums. The reprojected images are displayed to the user to simulate viewing of close range objects.

摘要： A real-time structured light depth extraction system includes a projector for projecting structured light patterns onto an object of interest. A camera positioned off-axis from the projector samples light reflected from the object synchronously with the projection of structured light patterns and outputs digital signals indicative of the reflected light. An image processor/controller receives the digital signals from the camera and processes the digital signals to extract depth information of the object in real time.
