Virtual prototyping of objects with thermal characteristic requirements depends on
several aspects such as the geometry of the component, material properties, ambient
environmental conditions and most importantly temperature curves/heat patterns of the
component when functional. In this case study, we present the data acquisition
methodology towards thermal modeling of as-built automotive parts into their virtual
prototypes. We explain the imaging-based reverse engineering pipeline suitable for our
application towards recovering 3D geometry and identify tools for measuring temperature
curves in the data collection process. Further, we show results of immersing the reverse-
engineered mesh in the thermal simulation environment and verify the finite-element
based simulation results to agree with the thermal image sequences. Our experimental
results based on automobiles are able to address the issue of thermal modeling and
verification of virtual vehicle components even when the computer aided design (CAD)
models are not available. Finally, we conclude our investigation with the experimental
achievability and limitations of imaging-based thermal modeling of vehicle components.
