    摘要： 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 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.

    摘要： A device for omnidirectional image viewing providing pan-and-tilt orientation, rotation, and magnification within a hemispherical field-of-view that utilizes no moving parts. The imaging device is based on the effect that the image from a fisheye lens (1), which produces a circular image of an entire hemispherical field-of-view, which can be mathematically corrected using high speed electronic circuitry (5, 6, 7, 12 and 13). More specifically, an incoming fisheye image from any image acquisition source (2) is captured in memory (4) 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. As a result, this device can be accomplish the functions of pan, tilt, rotation, and zoom throughout a hemispherical field-of-view without the need for any mechanical mechanisms. 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 used for any application where a conventional pan-and-tilt or orientation mechanism might be considered including inspection, monitoring, surveillance, and target acquisition.
