Multisensor Data Fusion for Nondestructive Evaluation of Bridge Decks

摘要

The nondestructive evaluation (NDE) of bridge decks often requires a combination of different methods for deterioration identification and characterization. Each individual NDE method also needs the responses of an array of spatially distributed sensors to better detect damages. Proper interpretation techniques are needed to effectively integrate data from different NDE technologies and sensor arrays of a single NDE method. A hybrid multisensor data fusion framework is presented in the paper for the NDE of bridge decks. The multisensor data fusion approach process, integrate and interpret the data from multisensor data of a single NDE method and a combination of various NDE technologies in a way that improves the accuracy and reliability of deterioration identification and characterization.
