摘　　要：灰度CMOS图像传感器由于去掉彩色滤光片,进光量是彩色CMOS图像传感器的三倍,故将灰度CMOS图像传感器和彩色CMOS图像传感器进行融合可以增加融合系统的夜视能力和动态范围。因此提出一种灰度与彩色图像融合算法,该算法是基于小波变换与HSI颜色空间转换的融合方式,同时提出一种基于梯度因子、灰度标准差、均亮度值的动态融合权值确定方式,并运用MATLAB等图像处理工具进行仿真验证。Gray CMOS image sensor due to remove the color filter, into the light are three times as much as for the color CMOS image sensor, so the gray scale CMOS image sensor and color CMOS image sensor fusion system can increase the fusion of night vision and dynamic range. Therefore, presents a gray and color image fusion algorithm, the algorithm is based on wavelet transform and the fusion of HSI color space conversion way, at the same time, puts forward an algorithm that is based on the gradient factor, gray standard deviation, mean brightness value weights to determine the way of dynamic fusion, and uses the MATLAB image processing tools such as simulation test and verify.
