Acquisition date: January 2020
Objective: Creation of a REVIT model of the interior and exterior as well as a Matterport
Approximate floor area: over 105 000 sq. ft
Level of details requested: LOD200 et LOD300
Number of scans: over 5 000
Cost of the project: 120 000$
Tools used:
- Leica RTC 360 scanner
- DJI Phantom 4 pro drone
- Tersus bi-phase GPS (control points)
- Matterport Pro 2 camera
Software used:
- Register 360 – Assembly of scans/point clouds
- Autodesk Recap – Visualisation 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
Methodologie used – Workflow:
- Acquisition of control points using GPS to control the scan quality and ease the assembly
- Drone flight and image acquisition needed for stereo-matching (photogrammetry)
- Scanning interiors and exteriors using scanners
- Acquiring 3D captures with a Matterport camera
- Assembly and georeferencing scanner scans with the 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 from the drone data with the point clouds from the scanner to cover the areas not covered by the scanner
- Revit modeling from point clouds
- Extraction of elevations and cleaning of vectors in 3D civil Autocad
