摘要:
A method and apparatus for sequencing views retrieved from a spherical still image file (6) provide the viewer the perception of video performance with low bandwidth transmission. The method incorporates digital transmission (9) and automatic sequencing (7) of the playback of the view. The apparatus provides video-motion rate images via low bandwidth digital transmissions or small data files from a still image taken of an inanimate environment. The resulting method and apparatus allows the viewer to experience a video display of any environment (for example, real estate locations, malls, museums, and hotels) and view a 'video' tour of the location through a low bandwidth transmission.

The present invention includes at least one camera (601) having a lens (602) with at least a 180 degree field-of-view for capturing a hemispherical image (603) corresponding to a mirror image of the hemispherical image (603) captured by the camera (601) and capturing the second image from a second camera. A converter combines (216) the two images along with their outside edges (207, 208) to form a single, spherical image (209). The apparatus for interactive display of any portion of a spherical image preferably comprises a digital processor apparatus (219) for storing digital data representative of at least one image having a 180 degree field-of-view. In order to view a selected image portion without warp or distortion at the seam between opposite hemispherical images, edge filtering is applied to eliminate a halo effect.
摘要:
A method and system for the creation and viewing of stereoscopic immersive images. By creating two immersive images from an offset camera platform (120), the illusion of depth can be provided by left and right view in the form of an interactive panoramic image. By capturing two immersive images on a fixture (110) with horizontal separation of the centers of each immersive image, each constructed from a sequence of fisheye images that are captured in a constant direction and seamed together, two files (294, 298) that can be used to produce a stereoscopic display are created. The resulting files can be displayed using any number of stereoscopic displays (440) including dual monitors, one for each eye, or shuttered displays for each eye from a single monitor, or displays with polarized filters directing separate views to each eye.

Computer software (150) and an associated digital camera system (100) for capturing digital wide angle such as hemispherical images, for processing two or more wide angle or hemispherical images to seam the wide angle or hemispherical images together to form a spherical image, for linking sound data files (105), location data (110), time and date data (100b) and horizontal reference data to the captured image data, for selecting for display (175) or for printing (165) undistorted portions of the spherical images (170), for posting the spherical images to a web site (160) or transmitting the spherical images via the Internet (155), for time and date stamping (100b) digital wide angle images as they are captured along with horizontal reference data, location data, for example, from the global positioning system (110), and environmental data.
摘要:
A device for omnidirectional image viewing providing pan-and-tilt orientation, rotation, and magnification within a selected field-of-view for use in any application including inspection, monitoring, surveillance, and target acquisition.. The imaging device (using optical or infrared images) is based on the effect that the image from a wide angle lens, which produces a circular image of an entire field-of-view, can be mathematically corrected using high speed electronic circuitry. More specifically, an incoming image from any image acquisition source is captured in memory of the device, a transformation is performed for the viewing region of interest and viewing direction, and a corrected image is output as a video image signal for viewing, recording, or analysis. Multiple simultaneous images can be output from a single input image. As a result, this device can accomplish the functions of pan, tilt, rotation, and zoom throughout the selected field-of-view without the need for any mechanical mechanisms to move a camera. The preferred embodiment of the image transformation device can provide corrected images at real-time rates compatible with standard video equipment. The device can be controlled by discrete user input, automatic computer scanning, or discrete environmental inputs to select desired output images.
摘要:
A method of inserting a high resolution image into a low resolution interactive image provides a greater sensation of virtual reality (presence) because increased magnification of the low resolution image, typically a wide angle image, reduces the sensation of virtual presence in the image. For example, according to the invention, as an image of the wall (2) of an art gallery becomes magnified in a virtual presence experience, a rectangular or other planar image portion such as a painting (3) that the user zooms on is replaced with a high resolution image stored and associated in memory. The virtual presence may be achieved by high resolution scanning a desired section of an image portion for overlay into the image scanned into a second memory at lower resolution. The high resolution image for insertion may be a dewarped portion of a fish-eye lens captured interactive image. Preferably, at least three reference points in the wide angle image and the planar image portion for insertion, such as the painting image (3), are identified and stored with the image data and a selected or predetermined magnification level. In this manner, the three image points can be manipulated and matched from the high resolution image to the perspective of the wide angle image. Also, for identity of perspective, the wide angle and high resolution images may be captured from the identical camera location. As the user inputs viewing angle criteria, such as pan and tilt angles, the rectangular image may be manipulated to match. The camera may be digital or analog, video, movie or still. Also, a high resolution photographic image may be inserted into a graphic image or vice versa.
