20080252728 | Airborne Laser Image Capturing System and Method - The present invention relates to an airborne laser image capturing system which comprises: (a) A laser source and laser focal plan array, both being mounted on a same gimbals platform; (b) A pulse generator for providing a series of pulses to said laser source during a scanning period, thereby activating laser illumination by said laser source during each of said pulses, the laser source being characterized in that its illumination beam is so concentrated that each pulse provides illumination of only a portion of the expected target; (c) A scanning unit for receiving a line of sight direction to a target, and for providing to the gimbals a scanning signal for effecting a sequential stepping-scanning movement in such a manner as to scan an area in which the target is included; (d) A motion compensation unit for providing to said gimbals, in addition to said scanning signal a motion compensation signal for compensating for the aircraft motion and for the aircraft vibrations; (e) A timing unit for: (e.i) Activating, in coordination with the said scanning unit, said pulse generator during the scanning period, in order to produce over the target a series of illumination spots, each relating to one of said laser pulses, and wherein each of said spots overlaps at least a portion of one or more adjacent spots; and (e.ii) Activating said laser focal plan array during the illumination of the target by each specific pulse in order to capture many of distinct spot-images, each relating to one illumination pulse; (f) A memory unit for receiving from said focal plan array the captured spot-images, and for storing them; (g) A correlating unit for correlating images stored in said memory by finding similarity between features of overlapping portions of neighboring spot-images; and (h) A combining unit receiving information from said correlating unit for combining the spot-images to form a complete image of the scanned area. | 10-16-2008 |
20100245571 | Global hawk image mosaic - A method of producing a mosaic image comprises the steps of capturing a plurality of overlapping images in a plurality of swaths, computing the relative displacement between adjacent ones of the overlapping images within the swaths, computing the relative displacement between adjacent ones of the overlapping images in adjacent ones of the swaths, and using the relative displacements to assemble the images into a composite image. | 09-30-2010 |
20130093885 | Aerial Imaging Array - An aerial imaging array including at least two imaging devices provided on a mount attachable to an aircraft, such that the imaging devices view downwards. Each imaging device has a field of view, and the imaging devices are arranged such that there is a gap between adjacent fields of view. Each imaging device has an image frame, and each image frame has a vertical centerline and a transverse centerline. The imaging devices are posed within the mount such that the projections of the vertical centerlines onto a horizontal plane are substantially parallel. The gap between adjacent fields of view is at least a quarter of the width of the smaller of the adjacent fields of view, and the viewing directions of imaging devices providing adjacent fields of view are less than 20 degrees apart. | 04-18-2013 |
20130258106 | METHOD OF USING AN IMAGE SENSOR - A method of using an image sensor onboard a satellite or an aircraft comprises two simultaneous sequences of image capture. The first sequence corresponds to a capture of observation images, and the second sequence corresponds to a capture of images dedicated to the detection of a shifting of the observation images. The images dedicated to the detection of the shifting are restricted to windows that are at least in part contained in a main window the of observation images. Furthermore, said images dedicated to the detection of shifting are captured at a frequency greater than a frequency of the observation images. | 10-03-2013 |
20130321626 | IMAGE CAPTURING - A camera assembly is disclosed for mounting on a vehicle (e.g. an aircraft). An exemplary camera assembly can include: a fixture (e.g. a rotatable drum); a camera; and a mirror; wherein the fixture is arranged to be rotated relative to the vehicle about an axis; the camera is mounted on the fixture such that the camera has a substantially fixed position relative to the fixture; the mirror is mounted on the fixture such that, if the fixture rotates, the mirror rotates; the mirror is rotatable relative to the fixture about a further axis, the further axis being substantially perpendicular to the axis; and the camera is arranged to detect electromagnetic radiation reflected by the mirror. The axis and the further axis may intersect. | 12-05-2013 |
20140211006 | IMAGING MACHINE WITH SEVERAL DETECTOR ARRAYS ARRANGED IN A FOCAL PLANE - An imaging device intended to be placed on board a satellite or an aircraft comprises at least two detector arrays that are arranged in the same focal plane. Each detector array itself comprises a unidirectional detector and at least one additional detector, produced on one same single-piece substrate dedicated to said detector array. The arrangement of the detectors in the focal plane is then carried out in a modular fashion, by positioning the respective substrates of the detector arrays. Several arrangements are proposed that are compatible with the unidirectional and bidirectional push-broom scanning modes. | 07-31-2014 |
