In order to make up for the defects of traditional temperature measurement methods, image temperature measurement technology is gradually applied to the measurement of temperature field of high-temperature objects. By analysing and demonstrating the feasibility of three-dimensional temperature field reconstruction in engine combustion chamber, the algorithm of temperature field reconstruction was put forward in this paper, the model between flame radiation energy and temperature field in engine combustion chamber was established, and the application of radiation imaging temperature measurement technology in aero engine annular combustion chamber test was preliminarily realized.
