Registration, correspondence, geometric descriptor.
For constructing a tri-dimensional model from range images, they must be registered, i.e., it must be put together
into the same coordinate system. There are good algorithms available to perform this, but only after the range
images have been brought into positions that are close to
the true ones with respect to an arbitrarily chosen reference
system. These initial estimates are often provided manually. This paper deals with a technique to compute them
automatically. We present a way to determine parameter
values that are necessary to control the control ﬂow of a
simpliﬁed mesh based crude registration, which is characterized by two novel features: drastic data reduction and an
expressive shape descriptor.
