Platforms & Sensors

Given the dimension of the area (ca 750 x 300 m) and the characteristics and complexity of the architectures, an integrated 3D surveying approach was selected. Photogrammetry and terrestrial laser scanning (TLS) methods were integrated in order to fully exploit the intrinsic advantages of the actual 3D recording techniques.

Different UAV platforms (swinglet and multirotor) were used to record aerial views (nadir and oblique images) useful for orthoimages generation and as integration to the terrestrial surveying and modelling. Most of the temples were recorded with terrestrial images, in particular for texturing purposes. The temples were also surveyed with different (TOF and phase-shift) terrestrial laser scanners.

 

Different archaeological artefacts in the museum were surveyed with digital cameras and triangulation-based laser scanners.
