通过分析海洋背景的人脸红外图像的特点，提出了一种基于概率统计的仿真图像建立方法。该方法首先采集大量的实验样本，统计生成红外人脸图像的概率模板，然后将生成的红外人脸图像通过灰度量化后嵌入到海洋背景红外图像中，再进一步进行平滑滤波，最终生成仿真图像。红外仿真图像的生成是红外仿真平台的主要部分，红外仿真平台可以为海上搜救红外目标检测的算法研究提供实验数据，为海上搜救研究搭建实验室研究平台。

This paper puts forward a method to realize simulation of infrared images, which has the sea background and human targets. The feature of human face on the infrared image has been analyzed, the probability statistical method has been used. Firstly, to collect a lot of experimental samples and realize the probability models. Then, to embed the simulation infrared human face into the infrared image which has sea background, through grey level quantization，and then to perform smooth filter. This image simulation method is an important part of the simulation platform，which can provide experimental images for the research on the infrared target detection of maritime searching and rescue.
