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
