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.

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.
