calib is a calibration routine for estimating the intrinsic and extrinsic
parameters of a camera. It accepts two kinds of input. The first kind of
input is the data file describing the correspondence between reference 3D
points and their image coordinates. The second kind of input is an image
in .pgm format and in square size. For further information about the .pgm
data see the .pgm man pages.
Output of this routine is a text file describing the estimated intrinsic
and extrinsic parameters including focal length, rotation matrix and
translation vector between the world coordinate system and the camera
coordinate system.
