correcting for perspective

[lucas418]

Hi: I'm trying to use ImageJ to measure lengths within an image. Is there
a way to correct for perspective? Many thanks.

Here's one page on camera calibration: http://kwon3d.com/theory/calib.html

And some basic theory and implementation details can be found in Tyson
Hilmer's senior thesis, which uses video:
