概要

Abstract: The use of portable and high-energy x-ray system can provide a very promising approach for the inspection of aged concrete structures. However, due to the effect of large scattering of low-energy x-ray in a thick concrete, the noise properties and contrast of the radiographic images need to be optimized to ensure reliable interpretation. Therefore, in order to improve the inspection ability, an image denoising method with the combination of wavelet and curvelet transform and image contrast enhancement approach using neighborhood operation is proposed to enhance the x-ray image for concrete bridge inspection in this work. To investigate the performance of this method for our system, we have performed several experiments with simulated and experimental data. It shows that the proposed image processing method can significantly improve the inspection performance.
