Acquisition date :2021
Approximative floor area : over 40 000 sq. ft
Level of details requested: LOD200 & LOD300
Number of scans:over 1 500
Cost of the project : 45 000$

Tools used :

  • Leica RTC 360 scanner
  • DJI Phantom 4 pro drone
  • Tersus bi-phase GPS (control points)

Softwares used:

  • Register 360 – Assembly of scans/point clouds
  • Autodesk Recap – Visualization and transfer of point clouds to Revit
  • Autodesk Revit 2019 – 3D modeling and BIM from point clouds
  • Autodesk 3D civil Autocad 2019 – Vectorization of point clouds
  • Agisoft Metashape – Photogrammetry

Methodology used – workflow:

  • Acquisition of control points using GPS to control the scan quality and ease the assembly
  • Drone flight and image acquisition required fir stereo-matching (photogrammetry)
  • Scanning interior and exteriors using scanners
  • Assembly and georeferencing of scanners scans with Register 360 software
  • Data processing of drone images by autocorrelation with Agisoft Metashape software and creation of the point cloud
  • Association of the point cloud form the drone data with the point clouds from the scanner to cover the areas not covered by the scanner
  • Revit modelling from point clouds
