A pipeline for enhanced multimodal 2D imaging of concrete structures

We present an imaging pipeline to achieve enhanced images of the interior concrete from ground penetrating radar (GPR) and ultrasonic echo array (UEA) measurements. This work lays foundation for advanced yet practical tool assess structures. Specifically, we propose two-dimensional (2D) total focusing method (XTFM) reconstruct raw GPR UEA data. The proposed XTFM algorithm integrates (TFM) synthetic aperture technique (SAFT) concepts post-process large independent interelement measurements both modalities in a computationally efficient way. Furthermore, introduce novel 2D image fusion using wavelet multilevel decomposition NDT knowledge-based rule fuse images. then compare our with conventional algorithms such as averaging, maximum, product. results three laboratory reference specimens are evaluated detail. fused compared each other well benchmarked original output obtained is structures that eases interpretation by human inspector it has potential improve computer vision analysis algorithms.
