Direct georeferencing of airborne pushbroom images

Journal of the Chinese Institute of Engineers, 2015
Direct georeferencing (DG) for orthoimage production based on collinearity equations has emerging as a standard photogrammetric operation. In this paper, the basic idea of DG is realized and refined with 19 self-calibration parameters for rectifying airborne pushbroom hyperspectral images collected using the intelligent spectral imaging system (ISIS ...

Resection method for direct georeferencing in Terrestrial Laser Scanner

Journal of Mining and Earth Sciences, 2022
Recently, the direct georeferencing method has been increasingly used in Terrestrial Laser Scanner (TLS). This method has the benefit of saving time, but the low accuracy is a great difficulty to use. This paper proposed a possible approach for direct georeferencing with high accuracy using the resection method.

Direct Georeferencing of Ultrahigh-Resolution UAV Imagery

IEEE Transactions on Geoscience and Remote Sensing, 2014
Micro-unmanned aerial vehicles often collect a large amount of images when mapping an area at an ultrahigh resolution. A direct georeferencing technique potentially eliminates the need for ground control points. In this paper, we developed a camera-global positioning system (GPS) module to allow the synchronization of camera exposure with the airframe ...

Accuracy analysis of MAMS data using direct georeferencing

2012 Second International Workshop on Earth Observation and Remote Sensing Applications, 2012
The conventional airborne photogrammetry is difficult to implement in some areas, such as marine, deserts, grassland and high mountain regions where the installation of ground control point (GCP) is dangerous or impossible. With the availability of integrated GPS and inertial measurement units (IMU), which are also called POS, this situation is ...

Accuracy of direct georeferencing strategies to monitor geomorphological features

2022
<p>Geomorphic systems face significant changes of climate, land uses, vegetation cover and socio-demographic characteristics. In this context, the accurate monitoring of geomorphological features may be a relevant tool to understand the consequences and the risks of these changes.
