Using Scene Constraints during the Calibration Procedure

This paper focuses on the problem of calibration from a single view and a map of a scene. This situation arises quite often when modelling urban scenes, e.g. for augmented reality purposes. We show how some scenes constraints can be used to achieve a calibration like procedure. An example excerpted from a sequence of pictures for which selfcalibration-like techniques consistently fail illustrates some of the benefits of the approach.
