There are many factors affecting the registration accuracy.According to the application of polynomial registration model in remote sensing image registration,this paper analyzes the following factors such as the terrain relief, the distribution of the control points,the degree of the polynomial,the image heterogeneity and so on.Finally,the multi-source images such as TM,SPOT and SAR images are used to conduct the registration experiment,and the influence rules of the above factors on multi-source image registration is concluded,which is helpful for the practical multi-source remote sensing image registration based on polynomial model.
