DRC: object recognition using Raspberry Pi

Well... now for some simple object recognition...

The program flow:

a) take an image; take a subsection as the reference object - calculate and store the SIFT descriptors for this image

SIFT descriptors

b) rotate DRC by 180 degrees.

c) take an image

d) calc SIFT descriptors and look for matches with the reference

e) if not many matches - rotate a little and go back to c)

Short post on Successful data out of OSLRF-01 Laser Range Finder

It's late and I'm going to bed. My eyes are blurry, and I've got a headache... but!!!

I'm getting reliable (for the most part) Distance readings out of the OSLRF-01 as evidenced here in my putty dump.  The "ACTUAL" distance to target was in fact 2.67m.  I've got a fairly consistent reflection or ghost at 0.67 and few more stragglers that I will work to filter, but I'm quite pleased.
