Hi Guys,

I found a great lens calculator if you are trying to figure out which lens to get for your camera:
http://www.videologyinc.com/lens%20focal%20length%20calculator.htm

Also this company makes more precise lens if you want to tune your FOV for optimal resolution.

Nice calculator.  I use a lot of Computar lenses so here is another lens calulator.

It also tells you the models and part number to use when you enter the perameters of your application.  Very Cool!

I’ve uploaded an excel chart on my store to help with calculating the m12 lens needed specifically for the ps3 eye camera.  Download it here: http://peauproductions.com/docs/ps3_lens_distance_calculator.xlsx

@ Peau: (I already post this in your blog, but it’s better post it here in the forum maybe)

Hi Peau, first of all, thanks for all the work that you share with all the MT community

I have a question, maybe a little obvious, but a make it just to be sure (I’m learning on the way smile)

In the excel, what it means exactly ‘Target’? The rectangle formed by Horizontal and Vertical lenght of the image projeted? or the rectangle formed by the edges of the surface? (in some cases, this could not be the same)

Thanks in advance, regards

The camera is in charge of seeing the touch surface where the blobs will be formed, so you want to put in only the area which you want the camera to track.  This usually is the area that the image is projected, as that is the area that the user is wanting to manipulate.
