Software prototype of the turbine blade cone-beam volume CT inspection system

The general architecture and data flow design for the software prototype of the inspection system were presented in this paper. The related research work were mainly focused on the implementing methods for the key modules of the software prototype, including: slice image stack fast reconstruction, high accuracy image edge detection, inspection model and CAD model alignment, wall thickness inspection and casting defects extraction etc. The software prototype was developed with Visual CH-6.0. Simulation results show that the software prototype is of the ability to perform hollow turbine blade profile deviation, wall thickness, and casting defects analysis based on its CBVCT scanning data.
