摘要： A system and method for radiographic inspection of aircraft fuselages includes a radiation source preferably located inside of the fuselage and a radiation detector preferably located outside of the fuselage. A source positioning system is provided for moving the radiation source longitudinally with respect to the fuselage, and a detector positioning system is provided for positioning the radiation detector in longitudinal alignment with the radiation source. The detector positioning system also moves the radiation detector circumferentially with respect to the fuselage. In operation, the radiation detector is moved over the fuselage in a circumferential direction while the radiation source illuminates an adjacent region of the fuselage with radiation.

摘要： A system and method for radiographic inspection of airfoil structure on aircraft includes a radiation source located on one side of the airfoil structure and an X-Y scanning device located on an opposing side of the airfoil structure. The X-Y scanning device is positioned to receive radiation from the radiation source. A radiation detector is mounted on the X-Y scanning device so as to be moveable relative to the airfoil structure along t two mutually orthogonal axes. In operation, the radiation detector is moved in a predetermined raster pattern while the radiation source is emitting radiation. This allows a large area to be inspected with single positioning of the X-Y scanning device, thereby improving throughput. The radiation detector converts impinging radiation into electrical signals, and a computer system processes the signals to generate radiographic images of the airfoil structure.

摘要： A method, system and apparatus for processing a radiographic image of a scanned object is disclosed. A pixel offset correction is performed in integer format on the radiographic image using saturation arithmetic to produce an image in integer format with any negative corrected values clipped to a value of zero. The resulting pixels are converted to floating point format and the converted pixels are multiplied by a gain factor. Optionally the resulting pixels are recursively averaged with previous results. The resulting pixels are converted to integer format and the converted pixel values are clamped to a maximum value using saturation arithmetic. Non-functional pixel correction is performed in integer format and the resulting pixel values are clamped to a maximum value using saturation arithmetic. An optional processing path replaces the recursive average by a linear average. The resulting pixel values are optionally filtered to enhance features of interest. The resulting pixel value is mapped in integer format to a palette index to establish an output pixel intensity having one of many intensity levels. The optional processing is controlled through the hardware interface of a real-time image controller as images are acquired.

摘要： A method (28) for manufacturing a precision part (18) utilizing a non-precision fixture (10). The non-precision fixture is precisely measured (40) and modeled in a CAD program (42) together with a model of the part (30). The part model is nested (48) into the fixture model, and a transformation matrix describing the movement of a coordinate system of the part during the step of nesting is recorded (50). The transformation matrix may then be used to transform (52) a tool path that had been developed for the originally designed shape of the fixture. Accordingly, imprecision in the location of a part within an imprecisely measured fixture may be accounted for during subsequent manufacturing operations.
