摘　　要：提出了一种基于HSI空间的假彩色异类传感器图像融合算法。该算法从边缘、色彩这两个图像的基本特征着手,在灰度融合图像的基础上,基于HSI空间,用色彩体现特殊传感器的独有信息。选用laplacian金字塔融合算法及一致性融合规则得到边缘灰度融合图像,并将其送至HSI空间的I通道;根据需要,将某特殊传感器获取的图像,送至H通道进行调制;最后将HSI空间的融合图像变换到RGB空间显示。仿真结果显示:本文算法得到的彩色融合图像不仅保留了与灰度融合图像相近的空间分辨率,而且突出了独有信息,是一幅信息量比较完备的融合图像。同时,对于HSI三通道的选择是固定的,具有很好的算法稳健性。A false color image fusion algorithm based on HSI color space for different sensors was proposed. According to two basic features of an image——edge and color,this method used colors to represent special information in HSI color space after obtaining a gray fusion image. First of all,an edge fusion image of two original images was obtained by a laplacian pyramid fusion method and the coherent fusion rule ,and then it was sent to I channel of the fusion image.Secondly,the special information was sent to H channel to be modulated. At last ,the fusion image was transformed from HSI color space to RGB color space to display. Compared to gray fusion image ,the color fusion image generated by this algorithm not only reserved space resolving rate,but also stood out special information. What's more,this algorithm was fixed to the choice of three channels to be more solid.
