  1. Title: Basics of 3D Scanning Data 04/21/2010 Prepared by Morgan Baron, Fellow – GK12 Program Presented at BCTS, Teterboro Campus Supported by:  NSF Graduate Teaching Fellow in K-12 Education Program Associated Institution: Stevens Institute of Technology - Hoboken, NJ  Introduce students to 3D scanning

  2. Basics of 3D Scanning • Use light to evaluate the surface of an object

  3. Time Of Flight Signal sent @ t = 0 Impact @ t = 1ns Object Transceiver Signal received @ t=3ns Return @ t = 1ns Distance = c x t/2 = 3x10^8 x 1.5 x10^-9 Transceiver Object

Golden Compass‘Best Visual Effects’2008 Academy Award Winner "The task of creating such highly realistic, computer-generated bears does not start on the computer," states Sean Varney, Sean Varney goes on to say, "We use the VI-910 digitizer from Konica Minolta to capture 3D data sets of each of the models

  9. Other Laser Applications NOAA's Aerial Photo of World Trade Center Image taken by NOAA's Cessna Citation Jet on Sept. 23, 2001 from an altitude of 3,300 feet using a Leica/LH systems RC30 camera. Image released Oct. 2, 2001 at 6:15 p.m. EDT (Image Credit: NOAA/U.S. Army JPSD) Remote Sensing

  10. Other Applications Do you know why I stopped you? Traffic Enforcement

  11. Other Applications Autonomous Vehicle Guidance

  12. Safety First

  13. Class 1 Laser Class I lasers are low powered devices that are considered safe from all potential hazards. Some examples of Class I laser use are: laser printers, CD players, CD ROM devices, geological survey equipment and laboratory analytical equipment. No individual, regardless of exposure conditions to the eyes or skin, would be expected to be injured by a Class I laser. No safety requirements are needed to use Class I laser devices.

  14. Procedure • Describe object and dimensions • Calculate distance of scanner • Place object • Adjust scanner • Scan • Evaluate

  15. Notes for Scanning • Consider using flat/featureless side for bottom • Capture side or sides with most features • We are using the telephoto lens • We will be using One Scan mode • Accuracy increases as distance increases, shadowing decreases as distance decreases

  16. Vivid 910 Guidelines
