  • Patent number: 7327897
    Abstract: Disclosed herein is a method of precisely correcting geometrically distorted satellite images. In order to correct a geometrically distorted satellite image, the position and attitude of a satellite must be accurately recognized. In this case, a correlation between the position and attitude values of the satellite exists, so accurate position and attitude values cannot be obtained. Therefore, the present invention accurately obtains position and attitude information of the satellite by separating variables having a high correlation to minimize the correlation between the position and attitude of the satellite and then calculating corresponding variables, and precisely corrects a geometrically distorted satellite image using the position and attitude information of the satellite.

  • Publication number: 20070223900
    Abstract: When composition of a first captured image having a tilted subject image is corrected, the first image is rotated such that the subject image stands in an erect position, according to the attitude of the camera achieved during capture of the first image. Images corresponding to missing portions, which arise in the image area for recording due to rotation, are extracted from a second captured image as compensation images. The second image is obtained by capturing an image of the same subject as that captured by the first image, at the different angle of view and attitude of the camera. An image obtained by enlarging the compensation images extracted from the second image according to the angle of view employed for capturing the first image is synthesized with the rotated first image, to thus make the subject image stand in an erect position and to obtain a corrected image without involving a decreased number of pixels.

    Abstract: Methods and apparatus for introducing a plurality of optical markers to a field of view, capturing a two-dimensional image of said field of view on an image plate comprising a pixel array, determining a set of marker origin offset values and using said offset values to establish a set of orientation values describing the relationship between the field of view and the image plate are disclosed. These orientation values are used to relate the area of image captured by each pixel in the image plate to the real world. By applying projective geometry, vector analysis and trigonometrical surveys an image analysis is conducted to establish a three-dimensional positional data set describing the three-dimensional position of regions of reflectivity in the captured two-dimensional image. From this data set a three-dimensional model of the field of view can be reconstructed.

  • Patent number: 5937213
    Abstract: A camera, such as a video camera or other electrically recordable camera, has scale imprintable capabilities and a method for imprinting a scale onto memory storage media. The camera and method imprints, optically or electrically, a standard scale on memory storage media for the purpose of estimating the size of a subject image. A photographic magnification calculation circuit calculates the photographic magnification based on a subject distance, and a reference scale setting circuit sets a reference scale for the purpose of estimating the size of the subject image on the memory storage media regardless of the magnification during picture taking or print size. An imprinting circuit imprints, optically or electrically, the reference scale onto the memory storage media in accordance with the reference scale setting circuit, and only when needed or wanted. The reference scale can be imprinted in a vertical or horizontal direction in accordance with a mode selection switch.

  • Patent number: 5903782
    Abstract: The present invention is directed to an apparatus and method for producing a three-hundred and sixty degree spherical visual data set using at least one lens. The lens encompasses a field of view of not less than one-hundred and eighty degrees. The field of view is represented by a hemisphere defined by a half-space which is, in turn, defined by a first plane having an origin point through which a vertical axis of the plane extends. The apparatus includes a mounting support member and a plumbing device. The mounting support member positions at least one camera having the at least one lens. The mounting support member is aligned with the vertical axis and rotatable in first and second directions through at least one-hundred and eighty degrees from a first position to a second position. The plumbing device is mounted to one of the camera, lens and mounting means and maintains the vertical axis plumb.

  • Patent number: 5764291
    Abstract: An orientation sensor generates a left orientation signal and a right orientation signal to indicate whether a camera is in an upright orientation, a left orientation, a right orientation, or an inverted orientation. A setting unit retrieves the left and right orientation signals and light intensity signals corresponding to image measurement zones. Based upon the values of the left and right orientation signals, the setting unit uses different weighted combinations of the light intensity signals to determine optimum exposure and focus settings. The orientation sensor includes a first tube and a second tube that each contain an indicating object. The indicating object within each tube selectively provides two orientation signals based upon the camera's orientation relative to an image, thereby changing an orientation signal from a binary "0" signal to a binary "1" signal.
