Leica Geosystems helps preserve French cultural heritage

Heerbrugg/Besançon - Leica Geosystems from the canton of St.Gallen is using modern laser scanners to produce a 3D model of the Citadelle de Besançon. Modern reality capture technology will help preserve and protect the structure, which is a UNESECO World Heritage Site.

The joint project of the French Government and Capture4Cad will use laser scanners from Leica Geosystems’ BLK portfolio for autonomous scanning of the Citadelle de Besançon. A press release explains that the modern scanners will be used to create a precise 3D model of the massive, 17th-century structure. This model will digitally preserve the citadel and allow visitors to explore it through augmented reality. Both these factors will help protect the future of the fortress, which is part of France’s cultural heritage and a UNESCO World Heritage Site.

A number of Leica Geosystems’ laser scanners are being used in the project. The Leica BLK2FLY autonomous flying scanner captured the towering ramparts, sheer cliffs, roofs and facades of the citadel. The versatile Leica BLK ARC was lowered 120 meters into France’s deepest well to thoroughly map the well shaft. It was also mounted to Boston Dynamics’ autonomous robotic carrier to independently map the grounds of the citadel. The handheld Leica BLK2GO scanner enabled uninterrupted scanning on the move through the underground tunnels.

“This ambitious project highlights how autonomous scanning solutions are uniquely positioned to help companies like Capture4Cad access complex sites to capture and process huge amounts of data,” says Giuseppe Mazzara, Director Sales Development at BLK Autonomy, Leica Geosystems.

“The range of Leica BLK autonomous scanners was essential to create the reality capture model of this expansive and intricate site. From capturing the point clouds to generating the 3D model, we’ve used Leica Geosystems solutions throughout this project to bring all the elements together,” adds Hugo Parent, Head of the Heritage Department at Capture4Cad. ce/ww
