Özet

Direct sensor orientation or direct georeferencing is the solution of exterior orientation parameters using GNSS\IMU data without ground control points. Accuracy of the system is based on GNSS\IMU integrated system accuracy. The integrated system containing DGNSS and IMU calculates the approximate exterior orientation parameters during the flight. The exterior orientation accuracy is based on GNSS and IMU accuracy. In this study, the effect of single point, network and PPP GNSS data processes without ground control point on the accuracy of the direct sensor orientation was evaluated. The area of the test region is approximately 1296 km(2). 393 images with 30 cm resolution were used in the study. It was calculated that single point solution horizontal accuracies are (X-Y) +/- 23-30 cm., vertical accuracy is (Z) +/- 40cm, network solution horizontal accuracies are (X-Y) +/- 24-27 cm, vertical accuracy is (Z) +/- 37 cm and PPP solution horizontal accuracies are (X-Y) +/- 20-28 cm, vertical accuracy is (Z) +/- 37 cm.
