Camera Calibration with Long Focal Length Using Building Natural Features

摘要：

In recent years, many researches are about building 3D object model in the fields of computer vision and photogrammetry, and camera calibration becomes the key problem. For long focal length digital camera calibration, there’s its particularity. In this paper, aiming at long focal length lens, a camera calibration method based on point-line combination with vanishing points is proposed. This approach overcame the demerit of the conventional calibration theory with vanishing points; therefore the precision of calibration parameters became better.
