Agenda

  • History
    • Why Scanning?
    • Technology
  • Current Scanning Technology
    • Type of Scanners
    • Improved Office and Field Work Flows
    • Where Used
  • What Lies Ahead
  • Questions
history
History
  • First Scanner for sale to public: 1998
  • Founder Ben Kycara
    • challenge yet to be solved: the ability to map “as builts” in 3D
  • Very specialized
  • Lots of training needed
  • Software limitations
history i st generation 1998 2000
HistoryIst Generation 1998 - 2000
  • Time-of-flight technology: laser rangefinder finds distance of surface by timing round-trip time of pulse of light (speed of light multiplied by time / 2)
  • 100 pnts/sec
  • 40o x 40o FOV
  • Costs for full system: Over $250,000
  • Sometimes they worked

HDS Executive Overview

in comparison to autocad release history
In Comparison to Autocad Release History
  • Laser Scanning Software about where Autocad was 20 years ago
slide8

Current Technology (Software)

  • Cyclone Software at Ver. 7
  • Registration: Automatic
  • Depending on task, some software very easy to learn
  • Getting more and more automated
  • Market Segment Specific Software
slide9

Current Technology (Software)

  • Market Segment Specific Software
  • Native point cloud support with no “Import” process required for Cyclone data
slide10

Current Technology (Hardware)

  • TOF
  • 50,000 pnts/sec
  • Distances up to 300m
  • FOV = Full Dome
  • Accuracy: 2mm on modeled surfaces
  • Phase Shift
  • 1,000,000 pnts/sec
  • Distances up to 187m
  • FOV = Full Dome
  • Accuracy: 2mm on modeled surfaces

Current Technology (Hardware)

  • MMI (Man Machine Interface)
    • Easy to learn
    • Press one button to scan
    • Touch screen control with stylus
    • Full color graphic display
    • No need for laptops
    • Review scans in MMI
what s next
What’s Next
  • Hardware: Merging speeds of Time-of-flight with phase shift
  • Hardware: total scantion like
  • Everthing more automated
  • Software much easier
  • Consumer grade scanners
  • Will be a part of process not an exotic tool
