Abstract
Generally, due to the partial occlusion, it is very
difficult to correctly estimate the central catadioptric line
image from its visible part. Except for the necessary and
sufficient conditions that must be satisfied by a set of paracatadioptric
line images, we find that if the antipodal points of
image points on the visible arc are known, the fitting accuracy
can be improved greatly. In this paper, we propose a
new method for fitting line images, which can be applied to
all central catadioptric projection. Firstly, a new relationship
between a pair of antipodal image points and the camera
principal point is derived. Next, using this relationship, a
new method is proposed to estimate the line images. These
estimated line images are used to calibrate camera intrinsic
parameters to evaluate the performance of our fitting method.
Experimental results on both simulated and real data have
demonstrated the effectiveness of our method.
