Laser Scanning (LiDAR)

Long-Range 3D Capture

Laser scanning (LiDAR) uses laser pulses to measure distances, creating point clouds of buildings, infrastructure, and large spaces. Works in any lighting.

Pros

  • Long-range capture (up to 1,000m+)
  • Works in any lighting conditions
  • Survey-grade accuracy (±1-2mm)
  • Penetrates vegetation
  • Excellent for large spaces
  • No surface preparation required

Cons

  • Higher equipment cost ($50K-$150K+)
  • Point cloud may lack color detail
  • Struggles with very dark/reflective surfaces
  • Larger, heavier equipment

Structured Light Scanning

High-Resolution Object Capture

Structured light scanning projects patterns onto surfaces to capture extremely high-resolution 3D data. Ideal for small objects and quality inspection.

Pros

  • Extremely high resolution (sub-millimeter)
  • Excellent surface detail & texture
  • Ideal for small/medium objects
  • Lower equipment cost ($5K-$50K)
  • Superior for organic shapes
  • Great for 3D printing output

Cons

  • Limited range (typically <2m)
  • Requires controlled lighting
  • Sensitive to ambient light
  • Multiple scans for large objects
  • May require spray for shiny surfaces

Our Expert Verdict

Tie - Choose Based on Your Needs

The choice depends primarily on scale and application. Laser scanning excels at architectural and infrastructure documentation. Structured light wins for small-to-medium objects requiring sub-millimeter accuracy.

Choose Laser Scanning (LiDAR) if...

Choose laser scanning for buildings, infrastructure, construction sites, and large-scale documentation.

Choose Structured Light Scanning if...

Choose structured light for product design, quality inspection, and small object digitization.

Frequently Asked Questions

Can laser scanning capture small parts?

Yes, but structured light provides better resolution for objects under 1 meter.

Which is better for reverse engineering?

Structured light for small parts; laser scanning for equipment and facilities.

Can I use both technologies?

Yes! Many facilities use laser scanning for buildings and structured light for product/equipment details.
