In this paper we present a robust method for the recog­
nition of 3D landmarks. Firstly the stereo and color
information are extracted and combined together to ac­
quire candidate 3D primitives of landmarks as super­
segments, and then structured indexing is incorporated
with pyramid and fuzzy methods. These approaches
prove to be successful in the off­line experiment for lo­
cating and recognizing many artificial objects from a
single view in indoor or outdoor scenes. The algorithms
to the approaches have been implemented on a parallel
computer system real­timely. A prototype navigation
system upon these algorithms and the parallel system
