摘要： A method for compensating for cross-talk in a 3-D projector-camera system having a controller including a processor and system memory and at least two channels, includes the steps of calibrating the projector-camera system, computing cross-talk factors applicable to the projector-camera system, and correcting new image data for cross-talk based upon the computed cross-talk factors. The system is calibrated by sequentially projecting and capturing, with a camera, a calibration image for each channel, to capture cross-talk between the channels. The controller can compute the cross-talk factors based upon the captured calibration images.

摘要： A method for reducing view-dependent artifacts in a multi-projector system includes the steps of measuring, from multiple viewpoints, projection characteristics of an image projected by a multi-projector system, estimating view-dependent projection parameters that can reduce view-dependent artifacts, and computing rendering parameters for each projector so as to reduce the view-dependent artifacts.

摘要： A method for reducing cross-talk in a 3D display is disclosed. The cross-talk in the 3D display is characterized with a plurality of test signals to generate a forward transformation model. Input image signals are applied to the forward transformation model to generate modeled signals. The modeled signals are applied to a visual model to generate a visual measure. The input signals are modified based on the visual measure.

摘要： Embodiments of the present invention disclose a system and method for multi-viewpoint video capture. According to one embodiment, the system includes a camera housing for accommodating both a first multi-imager set and a second multi-imager set, with each multi-imager set including a plurality of optical cameras having different viewpoint directions and configured to produce a source image. Furthermore, each camera in the first multi-imager set and the second multi-imager set include corresponding cameras facing in approximately the same viewpoint direction. The first multi-imager set is positioned laterally adjacent to the second multi-imager set such that lines joining a center of projection of corresponding cameras in the first multi-imager set and second multi-imager set are approximately parallel.
摘要翻译：本发明的实施例公开了一种用于多视点视频捕获的系统和方法。根据一个实施例，该系统包括用于容纳第一多成像仪组和第二多次成像器组的照相机外壳，每个多成像仪组包括具有不同视点方向的多个光学照相机，并且被配置为产生源图片。此外，第一多次成像器组和第二多次成像器组中的每个摄像机包括面向大致相同视点方向的相应摄像机。第一多成像仪组被定位成横向邻近第二多成像仪组，使得连接第一多成像仪组和第二多成像仪组中的相应摄像机的投影中心的线近似平行。

摘要： A method for automatic delivery of consistent imagery in a multi-projector system includes the steps of dividing the projectors into a plurality of sub-groups of projectors, each projector oriented to project a sub-frame to a sub-group display location, and adjusting the output of each projector in each sub-group to provide selected target display characteristics across all sub-groups.
