    Roquefavour Aqueduct

    Ventabren, France

Project Summary

Project

The project required ADG Drones Realisations (ADG ) to capture photos of the Roman aqueduct, Aqueduc de Roquefavour, in Ventabren, France, that could be used to generate a 3D reality model to inspect and assess the structural integrity of the national heritage site. Given the difficult access to the site and level of analysis necessary, ADG needed high resolution, aerial photographs and accurate reality modeling software to produce a precise textural mesh revealing the current condition of the aqueduct.

Solution

ADG used unmanned aerial vehicles (UAVs) flown at a low altitude to capture photos at a millimeter-scale resolution. The aerial imagery was first properly orientated and then used in ContextCapture to generate a precise 3D reality mesh revealing all cracks and existing conditions of the structure.

Outcome

Using Bentley ContextCapture saved ADG significant time, automatically producing a reality mesh from thousands of UAV photos of otherwise unreachable areas of the aqueduct. ContextCapture provided an accurate 3D mesh model that allowed users to extract valuable data for analysis. Leveraging the capability of ADG UAVs to capture millimeter-scale resolution photos with ContextCapture’s ability to automatically extract the finest details from the imagery obtained provided a cost-effective solution to assess the structural integrity of Roquefavour Aqueduct.

Software

ADG used ContextCapture to automatically extract fine details and valuable data from thousands of UAV photos to produce a 3D reality mesh of the Roquefavour Aqueduct. The textured mesh could then be used as a navigable model with the precise geometric accuracy to analyze damage and assess the structural integrity of the historic site, optimizing inspection and enhancing decision making for preservation.


Outcome/Facts
  • The 3D reality model provided the necessary detail to help analyze the damage and structural integrity of the aqueduct and enhance decision making to ensure preservation of the architectural site.
  • Using UAVs to capture millimeter-scale resolution photos and Bentley reality modeling software allowed ADG to obtain a precise 3D mesh revealing all cracks and existing conditions of the national heritage site quickly and efficiently.
  • ADG used ContextCapture to automatically generate a 3D reality mesh of Roquefavour Aqueduct from thousands of photos taken with their low altitude UAVs.
