| Abstract: | In this paper,a 3-dimensional modeling method is discussed for remote sensing images acquired by UAVRS~().Direct solution algorithm for relative orientation is applied to deal with the relative orientation for remote sensing images of low altitude.Base on experiments,analysis is conducted on accuracy of relative orientation influenced by degree of overlap between adjacent images.With the remote sensing images of big degree of overlap,a method for identification of the conjugate points is put forward to increase the accuracy of matching points.The method is based on the principle of epipolar line constraint among multiple images with big degree of overlap between each other.Experiments indicate that the method for 3-dimensional modeling is applicable to deal with the remote sensing images acquired by unmaned aerial vehicle remote sensing system. |
