MULTI-GNSS PPP: An Alternative Positioning Technique for Establishing Ground Control Points
International Journal of Environment and Geoinformatics, 2020 Traditionally, ground control points (GCPs) are utilized to determine absolute image orientations indirectly in aerial triangulation. For a long time, differential and relative GNSS (Global Navigation Satellite System) positioning techniques have been ...

Ground Control Point Automatic Extraction for Spaceborne Georeferencing Based on FPGA [PDF]
IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2020 Feature points that are obtained from the combined speeded-up robust feature (SURF) detector and binary robust independent elementary features (BRIEF) descriptor have a highly robust performance. These points are previously considered the ground control points (GCPs) for building a connection between the image coordinates and the corresponding geodetic

INS-camera calibration without ground control points [PDF]
2014 Sensor Data Fusion: Trends, Solutions, Applications (SDF), 2014 In this paper we present an approach for performing system calibration of a sensor suite consisting of a fixed mounted camera and an inertial navigation system without the usage of a photogrammetric calibration site. The aim of the presented work is to obtain accurate direct georeferencing of camera images collected with manned or unmanned aerial ...
