In the following figures we show the results of acquisition with 
the information about color in Fig. n. 7 and about brightness in 
the Fig. n. 8. 
Figure n. 7 The 3D model of the interior surface with RGB. 
Figure n. 5 Photogrammetric survey of stalagmites group. 
3.LASER SURVEY 
MENSI GS100 3D laser scanner is the exceptionally versatile 
solution for accurately capturing large sets of coordinates. With 
a 360° x 60° field of view and a range of 2-100 meters can 
capture large scenes or objects with less individual viewpoints. 
GS100 is capable of collecting up to 5000 points per second 
resulting in an highly detailed point-cloud data. 
GS100 provides highly accurate data after the merging of 
individual viewpoints. The scanner offers an uninterrupted 
panoramic capture of a scene up to 200m x 200m x 60m indoors 
or outdoors. As well as capturing 3D coordinates, GS100 
provides easy recognition of scanned data combined with color 
images of the objects created by an integrated video camera 
equipped with digital zoom. 
S.Caterine’s church 
The laser survey has been effected in two steps with the aid of 
3D targets of spherical form positioned in each one acquisitions. 
The first acquisition for the exterior surface and the second one 
for all the interior surface has been merged and we have 
obtained the 3D model. 
We see the plan projection of the cloud of over a million points 
in the Fig. n. 6. 
Figure n. 6 Two merged acquisitions (Plan View) 
Figure n. 8 The 3D model of the exterior surface with brightness 
From the 3D model so obtained, we can extract the mesh 
surface shown in the next figure n. 9 and all the section we need 
as we see also in figure n. 6 and n. 7.
