Recovering Partial Shape from Perspective Matrix Using Simple Zoom-Lens Camera Model

Abstract

In the 3D shape recovering using the perspective matrix, the calibration pattern needed to be contained in the input images. Therefore, it was difficult to use the images using zoom for 3D shape recovering.
  In this research, we used the simple zoom-lens camera model. And we realized the camera calibration in the state where the calibration pattern is not contained in the input images. Moreover, the validity of this research was shown by performing 3D shape recovering from the images using zoom.
