Photogrammetry has become an effectual measuring method, and was widely used. Based on adjustment theory model, this paper aims to derive position errors and error propagation model of the ground feature point (generalized point). For further analyzing the qualitative characters (such as precision, reliability, error ellipse) observed quantity, a concrete instance is given to certificate the proved conclusion has reference value on a certain degree.
