透过复杂介质获取目标物体图像精细信息的能力是光电图像采集处理的一大难点，选用 CMOS光电图像传感器，设计了CMOS成像系统以及后端读取和处理电路，透过毛玻璃对目标物体成像，将采集的图像信息传送到计算机中进行处理。该系统按照相机光学成像系统原理制作，采用通用CMOS图像传感器芯片完成电路设计，加之红外激光辅助照明拍摄采集图像，由远及近不同距离分别对同一目标物成像，对成像图像进行迭代图像增强算法优化，可以解决毛玻璃非匀质问题,使光源重建精度大大提高,得到的可见光图像轮廓清晰，与一般CCD成像系统相比，识别率超过95 %，远大于一般成像系统，且成像性能良好。

The ability to obtain fine information of object images through complex media is a major difficulty in photoelectric image acquisition and processing. The complementary metal oxide semiconductor (CMOS) photoelectric image sensor was adopted to design a CMOS imaging system and a back-end reading and processing circuit,the target object was imaged through the frosted glass, and the acquired image information is transmitted to the computer for processing.The system was fabricated according to the principle of camera optical imaging system. The circuit was completed by the general CMOS image sensor chip, and the image was acquired by infrared laser-assisted illumination shooting. The same target was imaged at far and near distances respectively, and the iterative image enhancement algorithm was optimized for the target image. It can solve the problem of non-uniformity of frosted glass, greatly improve the reconstruction precision of the light source, and obtain a clear outline of the visible light image. Compared with the general CCD imaging system, the recognition rate is over 95%, which is much larger than the general imaging system, and the imaging performance is good.
