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

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

Time Of Flight t = 1ns TransceiverObject Signal t = 0 t = 1ns Transceiver Object Signal t=3ns Distance = c x t/2 = 3x10^8 x 1.5 x10^-9

Safety First

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.

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

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
