Mapping pixels for distance

[Zumbalamambo]

How do I select a point in 2d image (either from the right camera or the left camera) and get the distance through the stereo vision?

I am also interested in the distance measurement of this code.

The measuring is not quite correct, I guess the parameters do not match my focal length.

In line 244 last parameters should be "disp", not filt_Color, I believe.

In line 31 - here happens the "measuring", add

disp = param

Then, when double-clicking in the stereo picture, it will output distances.

Have fun.
