摘要： A method and apparatus for processing imagery using images acquired via any known Electro-Optical (EO) system. In accordance with exemplary embodiments of the present invention, a first frame of data is selected as a template frame (e.g., a given frame). A second frame of data can be captured using the EO system. At least a portion of the second frame can be correlated with the template frame to generate a shift vector. The second frame can then be registered with the template frame by interpolating the second frame using the shift vector and re-sampling at least a portion of the second frame to produce a registered frame. The template frame can also be re-sampled. The registered frame and the re-sampled template frame can then be combined to generate an averaged frame. The averaged frame can be spatially filtered to enhance edges within the averaged frame.

摘要： A system and method are described for automatically determining the modulation transfer function (MTF) of an optical system. In accordance with exemplary embodiments of the present invention, optical information is collected from the optical system by imaging a bar target having at least one associated frequency to provide a bar target image for a first focus setting of the optical system. A first MTF of the optical system is determined for the at least one associated frequency at the first focus setting from the bar target image. The steps of collecting and determining are repeated by automatically selecting at least a second focus setting of the optical system to determine at least a second MTF for the at least one associated frequency. An MTF for the at least one associated frequency of the optical system is determined by interpolating the first and at least second MTFs. According to exemplary embodiments, a bar target with alignment holes is used for automatically determining the orientation of the bar target. In an alternate exemplary embodiment, an open-hole DC target is used to calculate the DC response of the optical system.

摘要： A method and apparatus for processing image data is described, comprising acquiring a frame of image data and compressing the dynamic range of the frame of image data using a dynamic range compression (DRC) algorithm that utilizes down-sampling, median filtering, and up-sampling. The DRC algorithm comprises down-sampling a frame of image data comprising a first array of pixels to generate a second array of pixels, applying a first median filter to the second array of pixels to generate a blurred array of pixels, up-sampling the blurred array of pixels, and removing at least a portion of low-frequency gradient data generated by previous steps from the frame of image data.

摘要： A method and apparatus for providing corrected values of gain and level coefficients of a set of correction coefficients for a scanning detector array, such as an IR detector array, comprising a plurality of detector channels is described. First values of the gain and level coefficients can be modified using at least one frame of image data collected by the scanning detector array from out-of-focus multiple-temperature imagery. Updated values of the gain and level coefficients can be determined using a scene-based non-uniformity correction (SBNUC) routine applied to scene data corresponding to focused scene imagery. The SBNUC routine can be applied iteratively such that updated values of gain and level coefficients converge to stable values.

摘要： A multi-mode detector and detection method that utilize shared optical components to detect multiple different incoming wavelengths of energy. Partial de-focusing of incoming light enables imaging and non-imaging outputs from the same detector. Analog and digital pixels enable mixed-mode output. Selective filtering at the detector enables the simultaneous detection of two or more wavelengths of light. Signal processing hardware and algorithms enable the system to simultaneously provide integrated and multi-channel analog outputs to guidance and display systems.

摘要： In a FLIR/laser based targeting and imaging system, the ability to recognize, detect, locate, and/or track targets in an area of interest is significantly improved by reducing the fixed and dynamic alignment errors between the IR LOS and the laser LOS. Fixed alignment errors are reduced with an improved internal boresight module and corresponding boresight method. Dynamic alignment errors are reduced with an opto-electric subsystem that employs a single pitch bearing and a common pitch/yaw afocal for both the laser energy and the IR energy. A segmented window in the system housing includes a circular EMI grid pattern which significantly reduces the amount of off-axis EMI entering the optical pathways, and improved signal processing techniques are employed to enhance the quality of the IR image after the image has been digitized.
