5. CONCLUSION
Due to the dramatic change of the radiation information on the
CE-limageries, the traditional method based on the gray and
line characters shows the limitation of achieving a satisfied
result. Moreover, the registration process among lunar images
which cover the whole moon has proved to be very time-
consuming. In this paper, based on the standard SIFT algorithm
a parallel and adaptive uniform-distributed registration method
for Chang'e-1 lunar remote sensed imagery was proposed. The
experimental results show the applicability of the proposed
method for CE-1 lunar imageries registration: it could generate
the matching points uniformly and effectively, and thereby be
used for the establishment of the lunar topographic map and
lunar geodetic network. However, due to the limited
experimental conditions, only the CE-llunar imageries were
applied for the registration. With the launch of the CE-2 and the
other lunar satellites, the further researches should conduct
higher multi-threads parallel processing experiment on large
amount and multi-source data, and then establish a foundation
for the automatic full-moon image matching and processing in
the next step.
