Aiming at the problems of stiff texture generation and realistic deficient in traditional infrared scene simulation,a new infrared texture generation method based on temperature difference disturbance compensation was presented. Taking measured infrared images as data source,the model of infrared imaging link was built through simulating infrared imaging. Environmental impact factors were decoupled to obtain the corresponding temperature of every pixel in infrared image,then objective surface thermal balance equation and one-dimensional heat conduct equation were established to solve the surface mean temperature in measurement time and simulation time,and then surface temperature difference disturbance was obtained through the difference between each point temperature and mean temperature in measurement time. Finally,surface predicted temperature distribution was gotten by temperature difference compensation for mean temperature in simulation time,and the calculated radiance data were saved as DDS textural format to improve the real-time of texture generation. The experimental results indicate that the method takes into account the reliability of real infrared data source adequately and the efficiency of infrared texture generation,and has good practical engineering value in infrared scene simulation.
