Agenda • History • Why Scanning? • Technology • Current Scanning Technology • Type of Scanners • Improved Office and Field Work Flows • Where Used • What Lies Ahead • Questions
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
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
Leica HDS Evolution High Definition Surveying
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
In Comparison to Autocad Release History • Laser Scanning Software about where Autocad was 20 years ago
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
Current Technology (Software) • Market Segment Specific Software • Native point cloud support with no “Import” process required for Cyclone data
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

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
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 • 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
