From image processing angle, the research on the infrared characteristics of burning decoy based on sets of measured infrared images is developed. After that, the infrared imaging model of the decoy is constructed. At last the lifetime infrared images of decoy are generated. In order to achieve the above objectives, firstly, an accurate segmentation and extraction for burning area, radiation area and burning trail of decoy is accomplished; secondly, the infrared imaging model of the decoy based on lifetime, size and gray of each part of the decoy is constructed; lastly, the infrared images of decoy are simulated by combination of billboard texture mapping technology and particle modeling. This paper provides the method combining Billboard and particle system with the trajectory of nodes, the system can enhance the precision of characteristics simulation and motion simulation for the infrared decoy, thus increase the real-time ability.
