Integration of multiple range and intensity image pairs using a volumetric method to create textured three-dimensional models

We present a volumetric approach to three-dimensional (3D) object modeling that differs from previous techniques in that both object texture and geometry are considered in the reconstruction process. The motivation for the research is the simulation of a thermal tire inspection station. Integrating 3D geometry information with two-dimensional thermal images permits the thermal information to be displayed as a texture map on the tire structure, enhancing analysis capabilities. Additionally, constructing the tire geometry during the inspection process allows the tire to be examined for structural defects that might be missed if the thermal data were textured onto a predefined model. Experimental results demonstrate the efficacy of the proposed approach and quantitative experiments indicate that the volumetric integration technique compares favorably to a state-of-the-art, mesh-based integration approach in terms of geometrical accuracy. Future research goals are also noted.
