  • Patent number: 6788333
    Abstract: A system and process for generating a panoramic video. Essentially, the panoramic video is created by first acquiring multiple videos of the scene being depicted. Preferably, these videos collectively depict a full 360 degree view of the surrounding scene and are captured using a multiple camera rig. The acquisition phase also includes a calibration procedure that provides information about the camera rig used to capture the videos that is used in the next phase for creating the panoramic video. This next phase, which is referred to as the authoring phase, involves mosaicing or stitching individual frames of the videos, which were captured at approximately the same moment in time, to form each frame of the panoramic video. A series of texture maps are then constructed for each frame of the panoramic video. Each texture map coincides with a portion of a prescribed environment model of the scene.

  • Patent number: 6778207
    Abstract: A virtual PTZ camera is described which forms a virtual image using multiple cameras whose fields of view overlap. Images from the cameras are merged by transforming to a common surface and property-blending overlapping regions to smooth transitions due to differences in image formation of common portions of a scene. To achieve high speed, the images may be merged to a common planar surface or set of surfaces so that transforms can be linear. Image information alone may be used to calculate the transforms from common feature points located in the images so that there is no need for three-dimensional geometric information about the cameras.

  • Patent number: 6762794
    Abstract: An image pick-up apparatus for capturing parallax images for the left eye and right eye which meet a fusion condition. A stereo camera image-captures a subject and displays captured parallax images on a stereoscopic display. An observer looks at the screen of the display. The lines of sight of both eyes of the observer are then detected, and a distance from the view point of the observer to the subject is measured based on the line-of-sight data. Instead of the observer, the apparatus determines whether the subject distance satisfies the fusion condition. The apparatus thus determines an image-fusible range, based on a (known) convergence angle, a (known) base line distance, a (known) size of the display, and the distance of distinct vision of the observer.

  • Publication number: 20040041905
    Abstract: Just after starting, right and left images, each of which includes a fixed object and does not include an intruding object, are read as background images. Background parallaxes are obtained from the background images. Subsequently, when an intruding object exists in the background images, motion pictures of the intruding object which is moving are read. The brightness of an arbitrary pixel in the right image is compared to the brightness of a pixel, deviated from the pixel by the background parallax, in the left image. As the result of the comparison, the image corresponding to the intruding object is cut from the right image. Consequently, the influences of a three-dimensional object existing in the background and an environmental condition are eliminated. The intruding object can be detected with high accuracy and high reliability.

  • Patent number: 6697100
    Abstract: Left and right video cameras 18L and 18R are disposed on both sides of a front video camera 18M. Solid-pictorial video signals used upon signal transmission are generated by using video signals outputted from the left and right video cameras with respect to a video signal outputted from the front video camera. The left and right video cameras make use of simplified video cameras and are cameras with no zoom functions or the like. The video signals obtained from the left and right video cameras are used as signals for forming a solid picture. In the present example, only solid information with respect to a main picture is transmitted as a video signal to reduce the amount of transmission. Since a motion-compensated DCT encode process using the front video signal as a reference picture is performed to extract only the video signal having the solid information from the left and right video signals. Since the simplified video cameras can be utilized, solid-pictorial video signals can be generated at low cost.

    Abstract: A client-server arrangement for camera viewing using digital cameras across a computer network. A camera server controls a motorized gimbal which determines the viewing angle of a camera, according to signals from a client computer which is equipped with an eye movement tracking system. Movements of the viewer's eyes result in changes in viewing angle of the remote cameras. The original full-resolution image is divided into a foveal area and a peripheral area. Subsequently, if a change in the peripheral area of a field of view is detected relative to the most recently displayed image, the viewing angle of the cameras is changed to center on the detected change, and an image is captured of this anticipated future field of view. When the viewer eventually changes his or her point of interest to the area of detected change, the pre-captured image is transmitted immediately for viewing.

  • Patent number: 6597807
    Abstract: Red-Green-Blue color-coding of overlaid registered stereo pair imagery from different spectral regions (for example, near-, mid-, and far-infrared) can be used to derive depth perception information. The human preattentive vision process uses coarse spatial structure in the scene to fuse the images for the detection of depth and motion cues. Optimization is accomplished by assigning green to the lowest spatial frequency content image, then red to the next lowest, and finally blue. If the fusion of one of the colored imagery layers produces depth perception information in one portion of the scene whereas the other two colored layers do not, the human mind can retain the information from this color and discard the inputs from the other two colors as noise. The same is true for the other two colors. Human color discrimination and depth perception are combined to greatly enhance preattentive object recognition in the fused stereo pair imagery.

  • Publication number: 20030025788
    Abstract: A 3D model of a scene is constructed by acquiring first images of a scene having unknown characteristics with a first camera. Corresponding second images of a another scene having known characteristics are acquired by a second camera. The first and second cameras have a fixed physical relationship to each other. Only the second images are analyzed to determine corresponding positions of the second camera while acquiring the first images. Then, the first images are assembled into the 3D model using the corresponding positions and the fixed physical relationship of the first and second camera.

  • Patent number: 6507359
    Abstract: Convergence angle information and image information of video cameras is transmitted from a multi-eye image-taking apparatus having two video cameras through a recording medium to a displaying apparatus. A convergence angle of display units in the displaying apparatus is controlled in accordance with the convergence angle information of the video cameras, permitting an observer to observe natural images. Since the convergence angle information is made ahead of the image information, the convergence angle of the display units can be changed with a natural feeling.

  • Publication number: 20020176499
    Abstract: Left and right video cameras 18L and 18R are disposed on both sides of a front video camera 18M. Solid-pictorial video signals used upon signal transmission are generated by using video signals outputted from the left and right video cameras with respect to a video signal outputted from the front video camera. The left and right video cameras make use of simplified video cameras and are cameras with no zoom functions or the like. The video signals obtained from the left and right video cameras are used as signals for forming a solid picture. In the present example, only solid information with respect to a main picture is transmitted as a video signal to reduce the amount of transmission. Since a motion-compensated DCT encode process using the front video signal as a reference picture is performed to extract only the video signal having the solid information from the left and right video signals. Since the simplified video cameras can be utilized, solid-pictorial video signals can be generated at low cost.
