4. CONCLUSION
Focusing on the buildings occlusion problem in matching with
city image, as well as the multiple solutions in matching due to
repetitive texture, this paper summarizes the existing multi-
view image matching algorithms, and proposes a multi-view
image matching algorithm for feature point supported by the
moving Z-Plane constraint. This paper selects three UCX digital
aerial images of a typical building area in the same strip for
matching experiments, and verifies the validity of the proposed
algorithm. The conclusions are as follows.
(1) The matching algorithm proposed in this paper can
simultaneously match with any number of multi-view image,
and obtains the matching results in any overlapping areas in
multi-view image ;
(2) Based on the selective matching, the MZPC algorithm
effectively avoids the effects by occlusion image, and improves
the reliability of the matched results;
(3) The MZPC algorithm does not need the iterative calculation
of height, and avoids the appearance of multiple peaks in the
cross-correlation curve caused by similar texture, and reduces
the probability of mismatches.
(4) The MZPC algorithm is entirely based on the matching with
feature points. The uniformity and the density of feature points
distribution directly determine the density of matching results.
It needs to further research the dense matching with other
matching primitives.
(5) The experimental results also have a few mismatched
homologous points. It needs to research a high reliable method
to reject the mistakes.
