DRONE AERIAL PHOTOGRAMMETRY
OLD CASTLE SITE OF ROUGEMONT-LE-CHÂTEAU
CULTURAL PRODUCTION ™ has performed an aerial photogrammetry project by drone at the Old Castle ruins site of Rougemont-le-Château in Territoire de Belfort – France
The objective was to realize the 3D textured model, the solid model and the orthomosaic map for integration on Google Map
Aerial photogrammetry takes all its sens on this old site
It makes possible to exploit the high potential of efficiency and precision of aerial photogrammetry by drone in relation of nearest old constructions or historical monuments restoration, but also of archaeological works and art structural inspection
Location: Boulles Mountains
Altitude: 736m
Description: Small castle from the Middle Ages whose foundations are intact. Recent excavations and restoration works have found the condition of the place hundreds of years ago
Information: The defined precision is 1.39 cm / px
For the validity of the project, 300 photographies are necessary from different angles, side and top views for best image resolution
Aerial photogrammetry by drone can achieve millimeter precision, which ensures high performance and less cost
Scouting location and flight verifications made, the aerial shooting started with ideal conditions on a day of may 2021, light wind and no cloud
The flight went perfectly, the aerial photographies necessary for the project were successful
After processing the captured aerial images, here are the achievements of dense cloud, textured 3D model, solid model and orthophoto by drone

ORTHOPHOTO BY DRONE
A LITTLE HISTORY...
• End of the 12th century: construction by Frédéric II, Count of Ferrette and Lord of Rougemont, of this fortress to monitor the Porte de Bourgogne and the road along the foot of the Southern Vosges
The trapezoidal-shaped enclosure enclosing a quadrilateral-shaped tower does not yet have a barbican. The stately home leans against the south wall
• 1295 Jean de Ferrette donates his “châtel haut de Rougemont” to his uncle Thiébaud de Ferrette
• Around 1300 reorganization of the castle following a fire, addition of the barbican, reconstruction of the circular tower on the basis of the rectangular tower
The stately home is moved against the north wall
• 1347 the Archduke of Austria, Albert II of Habsburg, inherits the seigneury of Rougemont. The village will remain Austrian until 1648
• 1375 siege and destruction of the castle by the bands of Enguerrand Sire de Coucy who ravaged southern Alsace at the same time
• 1648 treaties of Westphalia, the seigneury of Rougemont becomes French
• 1977 start of excavations by a team of volunteers from the Foyer Rural de Rougemont
• 1990 end of the excavation site, the site can accommodate the public
Some of the unearthed material is visible at the Historical Museum of the Château de Belfort
