An appropriate response to an emergency situation involving hazardous materials requires a good and accurate knowledge of the characteristics of the materials in question. Inspection and characterization of materials collected from hazardous environments is also of great value to first responders and security personnel. In this paper, we describe 3D modeling of material surfaces from stereo images obtained from a Large Chamber Scanning Electron Microscope (LC-SEM), a one of a kind microscope in the US. By applying an annealing based two-step energy minimization technique, the stereo images are reconstructed into 3D. A virtual 3D view obtained from the stereo pair verifies the validity of the automatic 3D model constructed. The spectral information at two energy levels, one for AlK and the
