Image mosaics based lens distortion correction of stationary camera

The traditional methods of lens distortion correction need man inference and don't be directly computed. The methods need ether calibrated reference objects or the correspondence information that men input. The paper provides the,way that can directly compute lens-radial distortion parameter. By means of alignment multi frames with rotating motion model, the way can correct the radial lens-distortion parameter. The paper gives a model and trial results. It deduces formulates. The trial results show the good correction for lens-distortion images.
