Abstract: The reverse modeling based on CT tomography technology provides an effective way for the three-dimensional (3D) modeling of metal rubber. However, due to the hooking and contact between the metal rubber wires, the 3D model has metal wire adhesion problems. From the scanned image, there are adhesions between part of the metal wire. In order to solve the adhesion segmentation problem, the marker-based watershed algorithm is adopted to deal with relatively simple adhesions in the cross section firstly, and then the axis coordinates of the wire are extracted by the 3D image skeleton thinning algorithm according to the geometric structure characteristics of the metal rubber wire diameter constant. Finally the 3D model of the metal rubber is reconstructed by using the sweep algorithm in the CAD system. Experimental results prove that this method can not only effectively realize the reverse 3D modeling of metal rubber and provide 3D digital models for metal rubber 3D simulation calculation and digital manufacturing, but also construct different porosities by changing the diameter of the metal wire or deleting part of the metal wire. The metal rubber provides a new idea for the limited parametric modeling of metal rubber.
