The underwater forest of Lake Tovel
As I wrote in a previous post, since 2005 Arc-Team is supporting Prof. Tiziano Camagna and Andrea Forti in their exploration of the underwater forest located in Tovel Lake (in Trentino - Italy). This project gave us some interesting data to test different techniques for underwater archeology, especially in the documentation field (like the use of SfM and IBM in extreme conditions).
I already reported some results of our experiments in this post and today I would like to publish the complete video we used to extract the 3d geometries of a flooded tree, thanks to the courtesy of Prof. Camagna, who kindly gave me the original record.
To help English reader, I translate here the superimposed text in the initial and final sequences:
"The underwater forest of Tovel Lake" (title)
"A landslide, as claimed by the studies conducted in 1992 by Oetheimer, caused the damming of the then envoy in 1597-1598, resulting in rising waters at the present level, submerging the forest located in the northeast of the lake" (intro)
"A photograph of the early '900 shows a tree of considerable size emerging from the water surface. This video shows the same tree today still firmly planted with its roots at the bottom of the lake." (intro)
"The under water forest of Tovel Lake;
people who participated in the making of the video:
Tiziano Camagna, Andrea Forti, Nicola Maganzini, Samuele Sozzi, Nadia Morani and Arc-Team (Cles) - Luca Bezzi and Alessandro Bezzi.

Currently Prof. Camagna started again with the exploration, while we will join him at the end of September (after +Alessandro Bezzi will return from the archaeological mission in Armenia). Soon we will post news and other reports regarding the project.
Have a nice day!
