Title: 3DCS Part 1 Data 3/04/2010 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 GK12 fellow’s research
Topics for Today • Purpose of 3DCS at Stevens • Components of system • LIDAR
Purpose of 3DCS • Large scale Data Collection • Test Bed for Next Generation Car Sensors • Symantec Description of Scene • Hierarchical System of Objects
Components • Velodyne HDL-64E LIDAR • Point Grey Research Ladybug 3 Camera • Six Point Grey Flea 2 video cameras • Applanix Position and Orientation System (POS LV)
LIDAR What is LIDAR? Light Detection and Ranging. What does that mean? Light used to determine distance to an object. How does it work? Any Guesses?
Time Of Flight We know some things • Velocity of light • Time that signal is sent • Time that signal is received
Distance from TOF 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
