Abstract
An effective multisensor data fusion and visualization framework is proposed for accurate localization and effective visualization of delamination in concrete bridge decks based on impact echo (IE) nondestructive evaluation method. The fusion rules are developed by analyzing the spatial distribution of surface motion resulting from mechanical impacts applied at different locations based on numerical simulation. The proposed approach can process, integrate and interpret the data from a series IE source-receiver arrays to improve the accuracy and reliability of delamination characterization for bridge decks. The visualization approach provides an intuitive way for users to visualize the internal defects of concrete bridge decks.
