Re: Measure distances w 1mm precision



As I know a sensor with 10000 x 10000 Pixel is not available. I know a
sensor with 13 000 x 7 000 and this cost approx "only" 20 000 Euro, of
course without housing and lenses :-).

Oyoyoyoyoy!

Faaar out of the window of the house where there was even a question
mentioning the budget of it. In that secret whispering way you know.
And in a foreign language. Faaar....

you
will have an field of view of 850 mm at a distance of 2 m. Lenses with a
smaller focal length are also really expensive and not accurate enough
for measurement systems.

Anyway, 85cm area surveilled sound good enough for me I think. Good
enough to make a try.

Yes, you can measure object positions better than 1 pixel in a image.
The easiest one is to have a round target.
Oh thank the God Of Round Objects (GORO?): my object is fairly round!
But for me to say even: a perfect sphere...

I think I have the holy advantage of trying, trying and trying again.
That is, I can collect samples. Pretty freely. As many as you want. And
even a few more if you´re kind.
