摘　　要：针对像素及多传感器图像的融合问题,设计了一种多传感器图像的彩色融合系统。该系统首先采用Laplacian金字塔变换算法得到灰度融合图像,然后产生共有图像、差异图像和细节增强图像,最后将灰度融合图像、细节增强图像,分别送入RGB通道得到彩色融合图像。实验结果表明,本系统可以有效地对多传感器图像进行彩色融合。根据熵和颜色丰富度两个客观评价指标,本系统的彩色融合图像更清晰,更容易识别目标,包含更多的细节信息,图像信息也更加丰富。Focusing on the fusion problem of the multi-sensor images for pixel level,the paper designs a color fusion system for multi-sensor image.There are three steps in the color fusion system.First,a gray fusion image of two sensor images is obtained by the laplacian pyramid transform algorithm.Then,common images,different images and enhanced image details are generated.At last,the enhanced image details and the gray fusion image are sent to R,G,B color channels respectively,and the color fusion image is obtained.Experimental results demonstrate that the designed system can generate the color fusion image for the multi-sensor images with highlight effectively.By using two criterions of entropy and color parameter,the final color fusion image generated by designed system has more color variation,more details using,and the targets is easy to be recognized.
