Rectification is a useful method to simplify sterescopic matching. In
this paper, a method for rectification of three independent views is
proposed. Using more views improves matching accuracy but there is no
linear rectification method for more than three cameras. This is the
reason we concentrate on trinocular rectification. Through
decomposition to projective and affine components, we obtain the
rectifing homographies with a linear computational method. It is shown
experimentally on real data that our algorithm performs the
rectification task correctly.
