A precise direct georeferencing system for UAVs

2014
A georeferencing of the collected data is required for many unmanned aerial vehicle (UAV)-based remote sensing applications in the fields of surveying, precision farming, infrastructure inspection or geography. This georeferencing can generally be done indirectly using ground control points, or directly using an on-board sensor system.

Direct georeferencing of ADS40 using calibrated POS data

2011 International Conference on Multimedia Technology, 2011
The ADS40 is airborne three-line-push broom imaging sensor integrated with POS, which developed by L. H. Corporation. Due to the accuracy of POS, especially the accuracy of orientation cannot meet the requirement for large scale mapping. This paper provides mathematical model for POS data calibration using a few GCPs.

A Comparison of Direct Georeferencing and GPS-supported AT

2006 IEEE International Symposium on Geoscience and Remote Sensing, 2006
One of the major tasks in the evaluation process of photogrammetry is the determination of the exterior orientation. Direct Georeferencing (DG) and GPS-supported AT provide new methods for this task in addition to conventional AT. A test flight was performed with two methods DG and GPS supported AT.
