Research on Large-Scale Scene Infrared Simulation Based on Image Classification

Vega has been widely used in Virtual Reality (VR) field. Vega infrared (IR) module can implement IR simulation, but Vega IR imaging simulation´s general approach does not apply to large-scale scene´s infrared simulation problem. This article deeps into large-scale scene IR image simulation through Vega infrared module based on visible image, the scene´s corresponding Digital Elevation Model (DEM) data and targets´ 3D model. A real time large-scale IR simulation system is successfully designed and realized in this paper. At the aspect of image classification, a coarse to fine k-means clustering method based on the consistency of image color is proposed. The proposed automatic texture material mapping method based on the development of Vega TMM tool provides a fast and convenient way for large-scale scene´s IR simulation based on Vega IR module. And finally, results of the large-scale scene infrared simulation show the effectiveness of this method.
