Abstract:
Recently, vision-based measurement techniques have emerged as an important non-destructive evaluation (NDE) method, due to the availability of low cost but high image resolution commercial digital cameras and effective image processing algorithms. In this chapter, some important issues that might affect the accuracy of the vision-based measurement techniques are presented and discussed. Results from laboratory tests and field tests are obtained to illustrate the accuracy and applicability of some vision-based measurement techniques.
