Resection method for direct georeferencing in Terrestrial Laser Scanner
Journal of Mining and Earth Sciences, 2022Recently, 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.

Accurate direct georeferencing of aerial imagery in national coordinates
ISPRS Journal of Photogrammetry and Remote Sensing, 2015In aerial photogrammetry, data products are commonly needed in national coordinates, and, in practice, the georeferencing is often performed in the required national map projection frame directly. However, as a map projection frame is not Cartesian, some additional corrections are necessary in the georeferencing process to take account of various map ...

Direct georeferencing of airborne LiDAR data in national coordinates
ISPRS Journal of Photogrammetry and Remote Sensing, 2013Abstract The topographic mapping products of airborne light detection and ranging (LiDAR) are usually required in the national coordinates (i.e., using the national datum and a conformal map projection). Since the spatial scale of the national datum is usually slightly different from the World Geodetic System 1984 (WGS 84) datum, and the map ...

Direct georeferencing of ADS40 using calibrated POS data
2011 International Conference on Multimedia Technology, 2011The 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.

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.

Accuracy analysis of MAMS data using direct georeferencing
2012 Second International Workshop on Earth Observation and Remote Sensing Applications, 2012The 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 ...

Direct georeferencing of oblique and vertical imagery in different coordinate systems
ISPRS Journal of Photogrammetry and Remote Sensing, 2014Reconstruction of 3D models through integrating vertical and oblique imagery has been studied extensively. For a 3D reconstruction, object point cloud coordinates could be calculated using direct georeferencing (DG) obtained from the direct orientation data of a GPS/INS system.

Approximate Correction of Length Distortion for Direct Georeferencing in Map Projection Frame
IEEE Geoscience and Remote Sensing Letters, 2013Many geometric distortions, such as earth curvature distortion and length distortion, exist in the map projection frame. Therefore, in aerial photogrammetry, if direct georeferencing is performed in the map projection frame, the crucial work becomes compensating for the effect of the various geometric distortions.
