GEOMETRIC ACCURACY TEST OF THE NEWEST LARGE FORMAT DIGITAL AERIAL SURVEY CAMERAS

摘要

The latest and technically more perfect digital aerial survey cameras require the further improvement and refinement of the calibration methods. To satisfy this requirement a new method was developed. This process analyses the accuracy of photo measurements by statistical methods in dependency of distance points from image center. The result of this new process led to a general consequence to show a functional connection between accuracy and radial distance and to provide a method how to check and enhance the geometrical capability of the cameras. The latest and most accurate large format digital aerial survey cameras have been tested in this paper with the newly developed radial variance component estimation. The conclusion shows the radial reliability of these cameras in several different real aerial projects.
