“…Data fusion is more and more employed in the NDT domain. The more commonly used methods are based on classification (like Dempster-Shafer theory) in particular for image fusion [3][4][5][6][7]. Data fusion is also already used for assessing civil engineering components [4][5]8].…”

“…These types of systems have been developed to allow for precise measurement grids that provide reconstructions of larger areas by stacking individually processed ultrasonic scans [40]. There have been multiple systems developed to accomplish these types of measurements [41][42][43]. However, the drawbacks of these systems include high cost as well as low flexibility and productivity.…”

a b s t r a c tQuantitative nondestructive characterization of defects and inclusions in portland cement concrete structures are realized in this paper via extended reconstructions for linear array ultrasound systems. This is accomplished through generalization of traditional Kirchhoff-based synthetic aperture focusing technique migration to mitigate the effects of limited aperture and handle multiple scans as a single virtual array with increased effective aperture. Pearson's correlation is utilized to account for uncertainty in relative position of individual measurement and mitigate the need for robotic precision when placing adjacent scans. The robustness of the method is demonstrated on artificially generated data as well as insitu measurements for assessment of internal portland cement concrete characteristics such as inclusions and cracks.

“…Ultrasonic inspection is used for non-destructive evaluation of concrete, typically, as a complementary tool to Ground Penetrating Radar (GPR) [1,2]. The Ground Penetrating Radar is mainly used to detect rebars and metallic tendon ducts in concrete bridge decks.…”
