A reconstruction method of temperature distribution in a 2-D absorbing-emitting system has been established based on radiant image processing. In this method, the radiant energy received by the image-formation elements of a CCD camera is dominated by the radiant energy emitted from the gas medium and the wall surface inside the system. The values of the ratio of the radiant energy received by the elements of the CCD camera to that emitted from every gas and wall element have been calculated using Monte Carlo method. Four CCD cameras are used to capture radiant energy images and the reconstruction problem of the temperature distribution is converted to a linear programming problem and solved through using an interior point method. After introducing random errors into the CCD's energy distribution, the temperature distribution of the system has been reconstructed with acceptable precision, which showed a great potential for application.
