由于应用需求的驱使,红外成像仿真技术越来越受到国际社会的关注,并已成为现代国防科技的关键技术之一。针对深空背景条件下的锥形目标,可利用结点热网络法求解其表面温度分布,然后计算目标与背景的红外辐射,再将探测器接收的辐射照度转化为灰度,并加入探测器自身效应的影响,就可仿真得到锥形目标不同成像状态的图像。此方法完整地实现了空间锥形目标在红外探测器上的成像过程,同时考虑了多种因素的影响,具有很高的真实性与逼真度,可为红外成像系统的研制及目标检测识别算法提供测试场景与依据。
Driven by the application requirements, infrared imaging simulation technology has drawn more and more attention from the international community and has become one of the key technologies in modern national defense science and technology. For the pyramidal target in deep space background, the thermal network of nodes can be used to solve the surface temperature distribution, then the infrared radiation of the target and the background can be calculated, and then the radiation illumination received by the detector can be converted into the gray level and added to the detector The effect of their own effects, you can simulate the conical target different imaging state of the image. This method completely realizes the imaging process of the space cone target on the infrared detector, and takes into account the influence of many factors, with high authenticity and fidelity. It can be used in the research of infrared imaging system and target detection and recognition algorithm Provide test scenarios and basis.
