Abstract: The problem of measuring two-dimensional temperature
field by CCD video camera is researched. The measurement mechanism of
CCD color video camera is analyzed, and tri-color thermometry model is
developed and analyzed. Because of complexity and non-linear of the
model, a method of calculating two-dimensional temperature field by BP
neural network is developed, which make use of the characteristic of BP
neural network in function approximation. Experiments indicated the
method is feasible and has a high degree of accuracy. The method has
bright prospect in industrial application.
Key words: CCD Video camera Temperature field Image processing
