| Caption | a) The Building A from 2015 acquisition by drone: orthoimage and extracted natural GCPs; b) The Building A from 2002 Rolleiflex acquisition: orthoimage; c) Views of point cloud densification (sx) and triangulated mesh (dx) with and without radiometric information, regarding the 3D model dated 2002 with Rolleiflex film camera acquisition; d) Investigation on density distribution of points clouds for (A-2002), mean density 36,400 pt/m³ (st.dev 11395), for (B-2015), mean density 1,500 pt/m³ (st.dev 358), and comparison between points clouds spatial geometry (mean discrepancy 0.06 m) and the mapping of changing areas. |
