基于扩散模型的水雾红外图像仿真研究

摘要

现有红外仿真软件处进行人造水雾图像仿真时，均无法体现出水雾的扩散特性，使仿真图像真实度较低。针对这一问题，基于高斯扩散模型与M IE散射理论，将水雾空间划分为多个子空间，通过计算不同子空间内的水雾特性参数，建立一种新型水雾仿真模型。根据所建模型，利用M atlab编程得到的仿真图像与现有软件仿真结果相比，图像真实程度有很大提高。%The simulation image could not display the scattering of water mist using the existing infrared simulation software, which makes the image unreliable. In order to solve this problem, the water mist space is divided into multi‐subspace. A new type of water simulation model is established using the calculation of water mist of different subspace parameters, based on Gaussian diffu‐sion model and MIE scattering theory. According to the new model, simulation image through Matlab is compared with existing soft‐ware simulation results to show that reliability of the infrared image has been greatly improved.
