Put something of known dimensions in your scene, then find it and measure it's length in pixels and in cm or whatever. Then compute the spatial calibration ratio of (real distance in cm)/(distance in pixels) to create a linear spatial calibration factor that you can then multiply by your pixel distances to get distances in cm.

See attached demo.
