Abstract

Structure from motion (SfM) comprises techniques for estimating 3D structures from uncalibrated 2D image sequences. This work focuses on two contributions: Firstly, a stability analysis is performed and the error propagation of image noise is studied. Secondly, to stabilize SfM, we present two optimization schemes by using a priori knowledge about collinearity or coplanarity of feature points in the scene.
