An Effective Methods for Non Metric Camera Calibration for Its Use in Accurate Close Range Photogrammetric Surveying

This study is on the effective methods for non metric camera calibration for its use in accurate close range photogrammetric surveying. We tested four estimation methods used for calculating interior orientation parameters and two methods for building calibration field, one is using targets which have three dimensional coordinates and the other is using two dimensional grid targets. By analysing test results effective and accurate calibration methods were suggested.
