3D object reconstruction from image sequences is an economic way to extract spatial information from observed scene. In a long period, people from remote sensing and photogrammetry fields interest the application of 3D reconstruction theory and technologies. However, for the application of 3D reconstruction in the field of photogrammetry, error estimation of the result must be fully demonstrated. In this paper, error propagation rules in 3D reconstruction process has deduced on the base of matrix analysis method, and a calculation method of covariance matrix is presented for estimate errors of elements of the reconstruction result, while the related factors' effects to the result are analyzed. In addition, experiments are introduced to demonstrate the error estimation for 3D reconstruction.
