Option A Mobile Technology

SLAM Scanning

Walk-and-scan mobile capture for 10x faster documentation

SLAM (Simultaneous Localization and Mapping) scanning uses continuous motion capture for rapid area documentation. Walk-through systems like NavVis VLX 3 can scan 500,000+ sq ft facilities in a single day—work that would take weeks with tripod scanners.

Pros

10x faster data collection
Large area coverage in hours
No tripod setup per station
Natural walk-through workflow
Handles stairs and multi-level
5mm accuracy with loop closure

Cons

Lower accuracy than static (5-20mm vs 1-2mm)
SLAM drift on long routes without loop closure
Lower point density than static
Not suitable for flatness testing
Repetitive features can cause tracking issues

Best For

Large facilitiesQuick as-built documentationMulti-story buildingsTime-critical projects

Option B Tripod-Based Technology

Static Scanning

Station-based scanning for 1-2mm survey-grade accuracy

Static (tripod) scanning uses fixed scanner positions for maximum accuracy and point density. Systems like Trimble X12 achieve 1mm accuracy—essential for floor flatness, bolt location documentation, and contractually defensible survey work.

Pros

Survey-grade accuracy (1-2mm)
Highest point density
Contractually defensible measurements
Floor flatness testing capability
Bolt-by-bolt location documentation
Best for engineering deliverables

Cons

Slower capture (tripod setup each position)
More scan positions required
Tripod access limitations
More expensive per sq ft for large areas
Multi-story requires separate setups per floor

Our Expert Verdict

Depends on Your Needs

SLAM is 10x faster for large area coverage with 5-20mm accuracy. Static achieves 1-2mm survey-grade accuracy required for engineering work. A 2024 study found "comparable accuracy" between methods, though static remains essential for flatness testing and bolt locations.

Choose SLAM Scanning if...

Choose SLAM (NavVis VLX 3, BLK2GO) when speed matters and 5mm accuracy is acceptable: large facilities, as-built documentation, time-critical projects.

Choose Static Scanning if...

Choose Static (Trimble X12, RTC360) when 1-2mm accuracy is required: floor flatness, engineering measurements, legal documentation, bolt locations.

Frequently Asked Questions

Can SLAM replace static scanning?

For many applications, yes. A 2024 research study found "comparable accuracy of static and new-generation SLAM scanners" with 20mm RMSD in 120m tunnels. However, flatness testing and bolt-by-bolt documentation still require static scanning.

How fast is SLAM vs static?

NavVis VLX 3 is up to 10x faster than tripod scanning. A 500,000 sq ft warehouse can be scanned in one day with SLAM vs. a week or more with tripod scanners.

What accuracy can SLAM achieve?

Top SLAM systems like NavVis VLX 3 achieve 5mm accuracy with proper loop closure and control point integration. Without optimization, typical accuracy is 10-20mm.

When is static scanning mandatory?

Static is required when measuring floor flatness, documenting exact bolt locations, creating contractually defensible surveys, or when specifications require 1-2mm accuracy.

Which does THE FUTURE 3D use?

We use both methods strategically: NavVis VLX 3 SLAM for large facilities and rapid documentation; Trimble X12 and Leica RTC360 static scanning for survey-grade engineering projects requiring millimeter accuracy.
