Abstract: We consider the problem of structure-from-motion (SfM) for images with varying principal point (PP) but otherwise fixed calibration. This scenario occurs for archival imagery taken using historic glass plate and film cameras without fiducial markers,… read more here.

Abstract: Abstract. We present an improved calibration method to optimize and simplify the current principal point estimation model and the zoom lens calibration process. A Euclidean distance weighting model (EDWM) for the principal point is constructed,… read more here.
