This paper illustrates an image processing technique using the Proper Orthogonal Decomposition (POD) of infrared thermal data for the construction of reduced models starting from experimental data. We consider a thin steel plate with a point heat source in the middle activated at time=0. A TELOPS DSP-83 fast IR camera collects a sequence of infrared image data. The 2D samples constitute the data set used to generate a POD empirical basis. Galërkin projection of the heat conduction PDE onto the basis generates the finite dimensional approximate dynamical system. Results are compared with experimental data and analytical solution.
