I know this is a little late coming in on this , but someone asked “which program opens this excel chart”.
If you don’t have excel, you could try Open office. It’s free:-)

Awesome man!!! Thanks a lot for these formulas! I didn’t know about how the CMOS size can alter FOV! Excellent!

Well, yes, but the angle of FOV is just a number that is usually given by the manufacturer, so you can’t really figure too much out using that number. See the excel sheet, it shows you the correct formulas on it.

Ha! Math class (trig) triangle, with 116 degrees (PS3 camera) on angle A, side a is the horizontal view so say 17.5″ (widescreen 19″). Assuming the camera is in the middle the other two angles are 32 degrees. Use Sine law to determine the sides, and then basic trig to solve for distance from angle A to side a

Am I right?

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.

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

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

Well, we are coming up on 3 years of it being out, so I am assuming everyone has the most recent Microsoft Office Excel 2007. If you don’t , download the compatibility pack. Guess I’ll have to put up a 2003 version for all of you late adopters.
Excel 2007 file extension = .xlsx
Excel 2003 file extension = .xls
