Abstract: | This paper describes a stereophotogrammetry method that reconstructs 3D microstructure surfaces from Scanning Electron Microscope (SEM) images. The microstructure surfaces are represented as 3D meshes with texture. The method's algorithm is based on the following stages: a) computing 3D points from 2D matched points; b) triangulating the 3D points into a 3D mesh; and c) mapping a 2D image as a texture on the surface. The textured 3D surface exhibits very realistic 3D microstructure surfaces for 3D visualization and engineering analysis. The performance of the proposed method has been analyzed and demonstrated on a variety of materials and complex geometries. |
