| 摘要： | The primary nondestructive testing devices currently in use by TxDOT are the falling weight deflectometer, the seismic pavement analyzer, the portable seismic pavement analyzer, and ground penetrating radar, which provide thickness or modulus information. In many projects a number of these devices are used. Results do not always coincide and thus decisions on either to combine values or decide on one value need not be made. Each device has unique strengths and weaknesses. Data fusion can be used to integrate the results from different devise in a synergistic way by utilizing the strengths of each method while minimizing the weaknesses. Data fusion allows for logical combining and filtering of information to obtain a composite value or a basis for decision. This report presents several data fusion alternatives for the synergistic analysis of data from multiple nondestructive testing devices. |
