摘　　要：DMCⅢ航空数码相机采用了新型的面阵CMOS传感器代替了原来的CCD传感器,导致影像亮度不平衡,严重影响了后期的空三加密工作。Wallis匀光算法主要用于多幅影像间的差异调整,能够有效地解决DMCⅢ影像的质量问题。本文详细地阐述了DMCⅢ影像的Wallis匀光算法,并结合实例进行验证,匀光效果理想。DMCⅢaerial digital camera uses a new array CMOS sensor instead of the original CCD sensor,which results in the unbalanced brightness of the image,seriously affecting the later work of aerial triangulation.Wallis dodging method is mainly used to adjust the difference between multiple images,which can effectively solve the quality problem of DMCⅢimages.In this paper,the Wallis dodging method of DMCⅢimage is described in detail,and verified by an example.The dodging effect is ideal.
