Self-calibration from Planes Using Differential Evolution

摘要

In this work the direct self-calibration of a camera from three views of a unknown planar structure is proposed. Three views of a plane are sufficient to determine the plane structure, the view's positions and orientations and the camera's focal length. This is a non-linear optimization problem that is solved using the heuristic Differential Evolution. Once an initial structure is obtained, the bundle adjustment can be used to incorporate more views and estimate other camera intrinsic parameters and possible lens distortion. This new self-calibration method is tested with real data.
