| Abstract;The 3-D shape reconstructed from images has a significant amount of uncertainty due to the innaccuracy of the data and the image processing procedures. Recently, Kinoshita and Tonko [7] showed that the accuracy can be improved simply by repeately taking images by an uncalibrated camera. In this paper, we summarize this methodology in a general framework and analyze a prototype problem to better understand the underlying geometric meaning. We point out the effectiveness and limitation of this method by considering the inherent uncertainty in doing projective reconstruction and applying gauge transformations. (author abst.) |
