OPEN PIT MINE 3D MAPPING BY TLS AND DIGITAL PHOTOGRAMMETRY: 3D MODEL UPDATE THANKS TO A SLAM BASED APPROACH
The state of the art of 3D surveying technologies, if correctly applied, allows to obtain 3D coloured models of large open pit mines using different technologies as terrestrial laser t5 dermatome scanner (TLS), with images, combined with UAV based digital photogrammetry.GNSS and/or total station are also currently used to geo reference the model.Th
