| Abstract Scope |
Synchronous measurement of temperature distribution with infrared cameras has been increasingly used in the thermomechanical analysis of sheet material behavior. Measured temperatures are used, however, only qualitatively due to absence of well-developed coordinate mapping methods applicable to thermographic measurements. The study introduces a primitive, easy to use, yet effective approach for accurate coordinate mapping from real to image coordinates, and inverse, applicable to even highly oblique thermographic and photographic measurements of planar deformations. The method is not limited to any camera model and precisely counteracts inhomogeneous image distortion. It can be used as a stand-alone optical measurement approach, but at the same time, it allows flawless correlation with commercial DIC systems by allowing accurate mapping between thermographic and photographic measurements of planar deformation in real and image coordinates. |
