多尺度多视点舰船目标红外视景仿真

Simulation of infrared scenes of a warship target with multi-scale and multi-viewpoint

基于模块化方法构建了舰船目标的多尺度多视点三维特征模型.根据大气传输参数、舰船材质的热物性参数和舰船温度分布,通过设置仿真软件Vega的Sensor Vision模块和Sensor Works模块参数,实现了舰船目标的多视点红外视景仿真.在此基础上,由多视点原始级别的红外仿真图像与二维高斯模糊模板进行卷积达到模糊降分辨率的效果,从而仿真出多尺度多视点的舰船目标红外图像.仿真结果表明,仿真生成的红外图像与实际图像较为接近,符合实际成像条件下的成像规律.

A 3D feature model with multi-scale and multi-viewpoint for a warship target was built by the modularization. According to the atmospheric transmission parametesr, the warship thermal properties parameters and the temperature of a warship target, the infrared scene of a warship target was simulated by setting sensor vision module and the SensorWorks module parameters in the simulation software Vega. The infrared simulation images of the original aspect images were blurred by eonvolving with two-dimensional Gaussian template so that the resolution of images was reduced and the warship target infrared images with multi-sca The simulation results indicate that the simu e and multi-viewpoint were simulated at the same time. ated infrared images are very close to the real infrared images, according with the real imaging process.
