Re: Day 3: Processor Choices for Embedded Vision
Eric Gregori   9/12/2012 1:13:23 PM

I'm thinking about "time of flight" for vision systems and seems it should use a reference pulse of light to measure the time-of-flight.

Do these systems use an expanded time sampling system to stretch 1ft/ns (2ft/ns RADAR time) to something much more measurable?


There are two methods used to measure TOF.  The first method measure the TOF directly using counters on each pixel clocked in the Ghz range.  The second method modulates the pulse using RF frequencies and measure TOF by the phase difference between the outgoing and incoming light pulse.
