Multi-source data framework: integrated survey for 3D texture mapping on archaeological sites

The aim of the present research is to test an integrated framework between the data obtained from the Unmanned Aerial Vehicle (UAV), a handheld thermographic camera (Infrared thermography) and the Terrestrial Laser Scanner (TLS). Piscina Mirabilis, in the city of Naples, becomes the benchmark to generate a comprehensive database, including a clear geometrical definition of the thermal variations of the wall surfaces by texturing the IR images directly on the RGB mesh surfaces. To measure the performance of mapping, the present research compared the quality of information by using 3D processing algorithms to optimise final the result.
