Project Objective
The project was aimed to capture 'as-built' data (Fig 2) of the entire Ta Prohm complex, which also includes the fallen members on each side of the temple for effective restoration works. The 'as-built' data should be able to provide sufficient data with better accuracy for restoration like: 2D Drawings, 3D Models and virtual tour of the site. The main objective of using 3D Laser Scanning instrument was to have better measurements and minimum survey time. The output data is directly kept in digital format for future reference.
Instruments used
1. Cyrax 2500 3D Laser Scanner with enhanced laptop loaded with specific software's (Cyclone Model, Survey, Register, Scan, Server and CloudWorx).
Cyrax can be used for the following applications:
- 'As-built' model of the existing structure for power plants, refineries
- Verification of existing drawings
- 2D Drawings & 3D models for heritage structure
- Topographic surveys of bridges & roads, terrain, rock faces, rail, tunnels
- Recording architectural details of buildings
- Quickly collect detail forensic evidence
- Rock & slope stability analysis
- For calculating the volume of excavated material from coal mines
2. TCR 307 Total Station from Leica Geosystems.
3. GS 5 GPS from Leica Geosystems.
Benefits of using 3D Laser Scanning in Archaeology
- Much faster than manual documentation methods
- Ability to measure inaccessible structures accurately
- Rapid scanning time reduced the minimized the project life cycle
- Collection of additional measurements for future use
- Ability to do as-builts without disrupting the tourists and ongoing works
- Captured details of the complex structures
New Dimension in Archaeological Documentation
Three-dimensional imaging has many useful adaptations. Museum curators wishing to create educational virtual reality displays can benefit from 3D Laser Scanning technology. It is quite another to feel as though you are stepping into the ancient tomb itself by means of a 3D model.
