3D Laser Scanning
(Terrestrial LIDAR)

  • Highest level of accuracy
  • Applicable indoors and outdoors
  • Highest possible point density
  • Farthest range (~1000 feet)
  • Best technique to record structural information
  • Cloudy weather is preferred for color scans
  • Black and white scans can be recorded in total darkness
  • Only what is visible from the ground or accessible neighboring buildings can be recorded.
  • Can tie data into a previously surveyed coordinate system.

Photogrammetry
(3D Reconstruction)

  • No LIDAR shadows due to occlusions
  • Can be augmented with LIDAR scans as additional 'survey control' to attain similar accuracy levels
  • Less data processing in the office
  • See/record what's not visible from the ground
  • Full photographic color
  • Scalable resolution, photo-scan a door knob, or an entire city.

3D Camera
(Matterport)

  • Lower accuracy (99.95%)
  • Faster recording per location
  • Least data processing in office
  • Full color
  • Lower point density
  • Needs ambient light
  • Sunlight interference (can be used indoors only)
  • Least range (20' between scans)
  • Virtual tour hosted online, 1 year included, can be extended
