Object Tracking using Camera and Lasers
Hey folks! Here's a little something I built about a month ago, but
couldn't get enough time from college to write about it. Well, it's an
object tracking camera panner which tracks any object moving in close
range. Unlike my previous method for object tracking, this technique
will track almost any moving object, irrespective of its color, using
two lasers for edge detection. Depending on which laser is focused on
the object, the computer decides which direction to drive. I came up
with this idea after watching a video on SoR (Society of Robots) of a
sumo robot, called Stampy. Stampy uses a single IR rangefinder for
edge detection. Watch the video below:
I used lasers instead of IR rangefinders. My initial plan was to use a
single laser..but then it occurred to me that I would have to shake
the laser left/right continuously for tracking the trailing edge of an
object. So, I decided to go with two lasers instead of one. :)
Well, I guess I've finally put my computer controlled stepper motor to
some use. I might be using this object tracking technique in my future
