基于可见光图像的红外场景仿真

针对景象匹配系统对红外图像的迫切要求,提出了一种利用可见光图像仿真生成红外图像的方法.首先,设计了红外场景仿真的总体方案;其次,对其中的基于可见光图像的材质信息分类、目标表面温度模型的建立及红外特征图像的生成3个关键技术做了初步实现;最后,结合红外场景仿真算法完成了典型电厂目标红外场景序列图的生成.实验结果表明:该方法生成的24 h序列图像与实拍红外图像的变化规律基本一致,从而为可见光图像制备红外基准图提供了一种有效途径.

IR scene simulation based on visual image

Aiming at the exigent request of the scene matching system to IR image, a method of IR image simulation based on visual image was proposed. Firstly, the overall project design of IR image simulation was given; secondly, several key technologies, such as material classification based on visual image, temperature model establishment of object surface, IR characteristic image production, were realized; finally, the IR scene image sequence of typical power objcet was produced with the algorithm of IR scene simu...
