摘要： A system and method for identifying flaws in a part being inspected includes generating a 3-d representation of the part, the 3-d representation comprising 3-d spatial coordinates corresponding to different locations on the part, and registering the 3-d spatial coordinates with corresponding locations of a part being inspected. An image of the part being inspected is generated, and a flaw in the part being inspected is identified from the generated image. A location of the flaw is correlated to a corresponding 3-d spatial coordinate, and a device is controlled to perform an operation on the part being inspected at the flaw location using information of the corresponding 3-d spatial coordinate.

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.
