DIRECT GEOREFERENCING OF TLS IN SURVEYING OF COMPLEX SITES
Terrestrial Laser Scanning Direct Georeferencing Architectural Surveying Civil Surveying Tunnel
2015/8/7
The high powerfulness of TLS technique for quick 3D data acquisition is extending its use to many fields. To further reduce the
surveying time and to simplify all operational tasks, the TLS direct g...
INVESTIGATIONS ON SYSTEM CALIBRATION OF GPS/IMU AND CAMERA FOR DIRECT GEOREFERENCING
Aerial Triangulation Calibration
2015/3/24
An inevitable task before direct georeferencing can be performed is the calibration of the GPS/IMU system and the imaging sensor.
The permanent calibration fields for large- and medium-scale (1:3 30...
THE IMPACT OF CONFORMAL MAP PROJECTIONS ON DIRECT GEOREFERENCING
Aerial Triangulation Impact Analysis Mathematics
2015/3/24
If an aerial-triangulation (AT) is performed in the National Projection System (NPS), then the conformal map projection (which is
the base for the NPS) effects the results of the AT by raising three...
