ABSTRACT
We present a computationally efficient method for estimat-
ing the trifocal tensor corresponding to three images ac-
quired by a freely moving camera. The proposed method
represents projective space through a "plane + parallax" de-
composition and employs a novel technique for estimating
the homographies induced by a virtual 3D plane between
successive image pairs. Knowledge of these homographies
allows the corresponding camera projection matrices to be
expressed in a common projective frame and, therefore, to
be recovered directly. The trifocal tensor can then be recov-
ered in a straightforward manner from the estimated pro-
jection matrices. Sample experimental results demonstrate
that the method performs considerably faster compared to a
