Abstract: A method for registering multiple projectors on a vertically extruded three dimensional display surface with a known aspect ratio includes recovering both the camera parameters and the three dimensional shape of the surface from a single image of the display surface from an uncalibrated camera, capturing images from the projectors to relate the projector coordinates with the display surface points, and segmenting parts of the image for each projector to register the projectors to create a seamlessly wall-paper projection on the display surface using a representation between the projector coordinates with display surface points using a rational Bezier patch. A method for performing a deterministic geometric auto-calibration to find intrinsic and extrinsic parameters of each projector is included.

Abstract: A projector configured to provide higher resolution output without increasing pixel resolution in a light modulator is disclosed. The projector may introduce an optical element between a light modulator and an imaging lens. The optical element may provide pixel sharing of a target image. The pixel sharing may be produced by, for example, making smaller copies of pixels. Selected copies of pixels may be passed to the imaging lens to display an output image with selected areas of higher density pixels.

Abstract: An augmented reality scene may be registered onto an arbitrary surface. A camera may capture an image of the arbitrary surface. The camera may analyze the surface geometry of the arbitrary surface. In some embodiments, a processing computing device may analyze data captured by the camera and an adjacent camera to reconstruct the surface geometry of the arbitrary surface. A scene may be registered to a three dimensional coordinate system corresponding to the arbitrary surface. A projector may project the scene onto the arbitrary surface according to the registration so that the scene may not display as being distorted.

Abstract: A method includes generating in a computer a representation for the color transfer function both direct and inverse, of a nonideal source device to those in a target device significantly different than the source device, using higher-dimensional Bezier patches by using a non-linear parameterization of the Bezier patches in the XYZ space for converting the RGB colors in the source device. The method is illustrated in an application for processing spatial variation in luminance and chrominance in a multiple projector display, which include the steps of balancing per projector white point, morphing per pixel chrominance gamut, constraining per pixel perceptual luminance; and smoothing per pixel Bezier based luminance.

Abstract: A method of distributed/cooperative/collaborative gesture management may comprise queuing actions of gestures as the gestures move across a display, processing the actions of each of the gestures by a projector in which the projector's display is close to a gesture, sending an anticipatory action message that one of the gestures is predicted to enter a display region of a projector, processing the actions of one of the gestures by a projector in which the projector's display is close to the one of the gestures, and in response to the one of the gestures being in an overlapping display projected by overlapping projectors, the actions of the one of the gestures are processed by the overlapping projector with the smallest identifier.

Abstract: An asynchronous, distributed, and calibrated apparatus provides a composite display from a plurality of plug-and-play projectors. The apparatus comprises a plurality of self-sufficient modules. Each module comprises at least one plug-and-play projector of the plurality of plug-and-play projectors. A camera is coupled to the projector. A software or firmware controlled, computation and communication circuit is coupled to the projector and executes a single-program-multiple-data (SPMD) calibration algorithm that simultaneously runs on each self-sufficient module to generate a scalable and reconfigurable composite display without any need for user input or a central server.

Abstract: A method is provided to smooth photometric variations across multi-projector displays. Photometric calibration is performed to generate a luminance attenuation map (LAM) for each projector. An image for each projector is modified using the luminance attenuation map (LAM) for each projector to provide image correction in real time. In the photometric calibration step a digital camera is used to measure the color response of the multi-projector display. Using the generated luminance attenuation map (LAM) for each projector for image correction in real time smoothes out distracting color variations across the multi-projector display while maximizing a perceived dynamic range of the display.
