Paper Abstract

This paper presents a new approach to integrated modeling of three dimensional objects for generating visual and thermal images under different viewing, ambient, and internal conditions. A volume surface octree is used for object modeling. It is shown that the above representation is suitable for thermal modeling of complex objects with non-homogeneities and heat generation. The technique to incorporate non- homogeneities and heat generation using octree intersection is described. The proposed model may be used to predict a discriminatory feature for object recognition based on the surface temperature and intrinsic thermal properties in any desired ambient condition. The model is designed to be used in a multi-sensor vision system using a hypothesize and verify approach. Several examples of the generated thermal and visual images are presented, which illustrate the usefulness of the approach.
