  1. 3D LASER IMAGING FOR ASSETT MANAGEMENT By Dr. Frank Young

  2. Interactive real-time 3D display, analysis, editing and modelling. Scanner Computer Tripod Battery Features of I-SiTE …… • A three-dimensional Laser Imaging System measures the position or object definition. • Records true colour and reflective intensity of 6000 points per second. • Uses a pulsed laser rangefinder and scanning system. • Ground based - easily incorporated with conventional survey or GPS.

  3. Specifications • Eye safe, class 1 laser • Range from 2m to 700m (or 350m optimum) • Extents < 340o horizontal < 80o vertical (± 40o) • Accuracy ±2.5cm per point (± 8mm for multiple scans) • Laser wavelength is 0.9 µm (near infrared) • 15kg in weight (including battery)

  4. How does it work? Scanning head Rotating mirror Laser Pulse and reflection Detector Pulsed Laser diode Target

  5. Scan resolution example: Geotechnical/slip failure

  6. ScannerSoftware • Computer controlled data acquisition and scanner control • Create lines, polygons, points and construction planes. • Can edit scanned data. • Automatic edge detection, filtering, smoothing, shading, transparency and colour manipulation. • Variety of export formats.

  7. Edit example: filter to remove high or low points. High objects Low object

  8. Precise volumetric measurements. • Stockpile monitoring and management. • Geological face mapping. • Virtual scene creation. Applications • Detailed survey of complex surfaces, industrial sites and hazardous areas. • Underground void, stope and geological face mapping. • Local Government/city Mapping, GIS Data collection. • Accident and crime scene Mapping.

  9. Some advantages …….. • Single person operation. • Accurate and rapid data acquisition. • Combined multiple scans coverage of a scene. • Feature mapping, texture draping and mosaicing. • Accurately maps - full 3D. • Safe, remote stand-off and high speed operation. • Portable. • Rapid digital recreation for analysis and real time visualisation.

  10. The real World to ScanData image to 3D Model Mapping complex scenes in full 3D from a single remote stand-off vantage point

  11. Detailed heritage asset recording with 3D accuracy
