We have already proposed the techniques to identify the parameters and to detect a small crack in the cantilever beam using the image processing. In this paper, we intend to improve an accuracy and to reduce the calculation time in our proposed techniques. By optimizing the location of nodes in the Spline smoothing, we could reduce the error in the image data and get more precise deflection data of the beam. The time consuming part in the damage detection program using the simulated annealing technique was the FEM calculation of the deflection of the beam. After introducing the nonlinear but exact model of the beam element into the calculation of the beam deflection, the significant reduction of the calculation time was achieved in this paper.
