Abstract
A fast camera calibration technique to estimate the cen-
ter of perspective projection of an imaging camera has been
described. The proposed technique requires a single im-
age of two planar calibration charts arranged in a special
manner. The special arrangement of the calibration charts
simplifies the projection equations relating the 3-D scene
coordinates to the 2-D image coordinates and they can be
suitably combined to eliminate the unknown intrinsic pa-
rameters other than the desired center. We have analyzed
the error in the center estimate due to various alignment er-
rors in the experimental setup, and shown that the scheme
