Super-Resolution Reconstruction for X-Ray of Turbine Blade

  • Based on non-destructive testing system for turbine blade,propose a resolution enhancement approach for X-ray DR digital image.In detail,firstly,we present a frequency domain technique to precisely register a set of digital X-ray image of turbine blade,which are translated,rotated against each other within at least the subpixel dimension,then a high-resolution image is reconstructed by using nonuniform interpolation.We demonstrate the ability of the approach to improve resolution of X-ray image of turbine blade,and the resulting high-resolution image show good visual results;it also contains more detail that can be exploited for zooming in non-destructive inspection.
