Computed tomography inspection of composite ply structure |
摘要 |
A method of computed tomographic inspection which uses a Euclidian reference ply model having a corresponding Non-Euclidian ply model which includes reference model plies to extract intensity data from Euclidian slice data (typically having a pixel format) derived from multiple slice X-ray scans using an X-ray scanning system such as the CT system. The multiple slice data is analyzed to determine intensity values for points corresponding to a subject ply of a corresponding reference model ply. The reference model may be a predetermined model such as a mathematically described CAD model file or based on such a CAD model. A preferred method of the present invention includes a transformation of the CAD model data to register the CAD model data to multiple slice data of a standardized object to generate the reference model. Intensity values preferably gray scale pixel values are assigned to points on the reference ply model from the slice data and displayed as a Non-Euclidian image on a monitor.
