Mobile SLAM scanning and terrestrial (tripod) scanning are complementary technologies. The right choice depends on your project's size, accuracy requirements, and timeline constraints.
Mobile SLAM Scanning (NavVis VLX 3, NavVis MLX):
- Speed: 200,000-300,000 sqft/day
- Accuracy: ±5mm (±3mm with control points)
- Setup: Operator walks through space continuously
- Best for: Large facilities, active environments, speed-critical projects
- Limitation: Not suitable for sub-millimeter precision work
Terrestrial Scanning (Trimble X12, FARO Focus Premium, Leica RTC360):
- Speed: 20,000-30,000 sqft/day
- Accuracy: ±1-2mm at typical distances
- Setup: Tripod placement at each position (2-5 min per scan)
- Best for: Engineering-grade documentation, structural analysis, high-precision metrology
- Limitation: Slow for large facilities, requires clear line of sight
When to Choose Mobile:
- Facility is over 50,000 sqft
- Speed is more important than sub-millimeter precision
- Scanning during active operations (no shutdown)
- Digital twin or facility management documentation
- Budget-conscious projects where speed reduces field days
When to Choose Terrestrial:
- Engineering or construction tolerance requirements (±1-2mm)
- Structural assessment or deviation analysis
- Regulatory documentation requiring survey-grade accuracy
- Small to medium spaces (under 20,000 sqft)
Hybrid Approach (Best of Both): THE FUTURE 3D frequently deploys both technologies on the same project. Mobile SLAM rapidly captures the overall facility, while tripod scanning provides high-accuracy data for critical areas (structural connections, mechanical rooms, control points). This approach combines the speed of mobile with the precision of terrestrial.
