MEASURING TWO-DIMENSIONAL TEMPERATURE FIELD BASED ON DIGITAL IMAGE PROCESSING TECHNIQUE

Abstract

Abstract: The problem of measuring two-dimensional temp- erature field by CCD video camera is researched. The measu- rement mechanism of CCD color video camera is analyzed, and tri-color thermometry model is developed and analyzed. Beca- use of complexity and non-linear of the model, a method of calc-ulating two-dimensional temperature field by BP neural netwo-rk is developed, which make use of the characteristic of BP neu-ral 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: BP neural network, CCD, Image processing, Measurement, Temperature field, Video camera
