  2. Agenda • History • Why Scanning? • Technology • Current Scanning Technology • Type of Scanners • Improved Office and Field Work Flows • Where Used • What Lies Ahead • Questions

  3. 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

  4. 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

  5. Leica HDS Evolution High Definition Surveying

  6. HDS Markets and Applications (Now)Fast, Accurate, Detailed Geometry Capture of Sites, Scene and Structures •  Building • As-built 3D BIM • As-built 2D drawings • Full colour visualisation • Clash detection • Industrial Plant  • Intelligent 3D CAD as-builts • Revamp design clash detection • Construction planning •  Civil & Survey • Topographic road, rail surveys • Volumes • Tunnel surveys • Forensics  • Crash investigation • Collapse analysis • Security planning HDS Executive Overview

  7. In Comparison to Autocad Release History • Laser Scanning Software about where Autocad was 20 years ago

  8. 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

  9. Current Technology (Software) • Market Segment Specific Software • Native point cloud support with no “Import” process required for Cyclone data

  10. 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

  11. Smart X-Mirror Design Camera LIDAR

  12. Current Technology Time-of-Flight Total Station on Steroids Removable carrying handle Radio antenna Rotating vertical mirror and camera Touch screen with color graphic display Rotating horizontal turret Internal hard disk External bubble Internal battery Dual Axis Compensator ON/OFF button Power connector in non-rotating base USB port Ethernet connector in non-rotating base Stylus Laser plummet

  13. HDS7000 Phase-Shift Radio antenna Stylus Carrying handle ON/OFF button Rotating vertical mirror USB ports Lemo ports Internal flash drive Touchscreen with color graphic display Dual Axis Compensator Rotating horizontal turret Internal battery Power connector in non-rotating base Ethernet connector in non-rotating base Laser plummet

  14. 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

  15. 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
