摘　　要：随着传感器和探测手段的增多，现在人们所面临的问题已由过去的信息匮乏转向了信息过多但应用不充分。多源遥感影像融合技术可提高影像分辨率和改善影像质量，有利于目标定位与识别，提高现有影像的应用价值，对于目标识别、疾病诊断、交通控制、地质探测、自然灾害预报以及安全监测等诸多领域的应用都有积极意义。本文介绍了多源遥感影像融合技术的常用方法以及各方法的优缺点，为实际应用中根据使用目的和侧重点不同进行融合方法选择提供参考。With more sensors and methods for detecting, the current problem has been changed from information lacking to information deluge, and the collected information are not fully developed. Multi - source remote sensing image fusion can improve the resolution and quality of the image, and it will be helpful in object orientation and recognition. Moreover, it can increase the application value of images and has positive significances in various fields such as target recognition, vegetation disease detecting, transportation controlling, geological surveying, natural disaster forecasting and security monitoring. The paper introduces common- ly used technologies for multi- source remote sensing image fusion, and discusses the advantages and disadvantages respectively. The study will provide references for choosing fusion methods according to the purposes of different projects.
