Abstract
A novel three-dimensional reconstruction method based on MATLAB and μCT scanning technology is used to rebuild the FEM model of aluminum foam. First of all, the μCT is employed to scan the aluminum foam, which is shown in (a). Secondly, the maximum entropy algorithm is employed to obtain the binarization image, and median filtering algorithm is used to reduce the “salt & pepper” noise after binarization; the external contour and internal pore boundary is extracted by the “edge” function in MATLAB, which is shown in (b). Thirdly, geometrical model for the foam plate is reconstructed as shown in (c). Finally, a two-step mesh algorithm is used to mesh the reconstructing geometrical model shown in (d).
