Contrast on infrared tank simulation software system based on 2D/3D

The distributing characteristic of radiation field was actualized by 2D/3D methods. In previous way, the 2D mapping images were classified into several regions and each of the regions reflected one material. Based on the different characteristics of materials, several infrared physics formula were managed to calculate the materials radiant exitance (MRE) in given infrared waveband, then the different MRE were calculated to corresponding gray level. After that, a gray level 2D map was achieved to simulate the radiation field when mapping on tank. In latter way, based on the infrared physics, the factors that affected tank radiation field distributing (TRFD) were analyzed, then TRFD was derived by mathematical model. Adjacent vertex matching was implemented according to the TRFD and then the vertex color was processed. In order to construct a highly precise and equitable infrared environment, both methods adopted the same atmosphere transmission model and detector noise engendered model. Finally, the open-loop experiment with digital micro-mirror device (DMD) was built up to simulate different typical images of tanks.
