This calculator helps you selecting the right lenses for your cameras. It does so by computing
the desired focal length, the corresponding field of view and the expected depth of field. In case of a stereo camera,
such as our Karmin2 3D stereo camera, the
calculator also helps you selecting the baseline distance and it provides information on the expected depth error.
You have several options for determining the focal length: you can enter the focal length manually,
specify the desired field of view, or determine the focal length from the object of interest's size and distance.
For computing the baseline distance of a stereo camera you further have to enter the minimum depth at which
you want to be able to perform stereo matching and the considered disparity range. The baseline distance is then
computed such that depth measurements at the minimum depth will have the maximum disparity value.
