ICP fit Points in data to the Points in model. Fit with respect to minimize the sum of square errors with the closest model Points and data Points.
Ordinary usage:
[R, T] = icp(model,data)
INPUT:
model - matrix with model Points,
data - matrix with data Points,
OUTPUT:
R - rotation matrix and
T - translation vector accordingly
so
newdata = R*data + T .
newdata are transformed data Points to fit model
see help icp for more information
Example - 3-D Stem Plot of an FFTFor example, fast Fourier transforms are calculated at Points around the unit circle on the complex plane. So, it is interesting to visualize the plot around the unit circle. Calculating the unit circle.
Generate a great circle "trajectory" from [lat1,lon1] to [lat2, lon2].
％ Resulting Points will be seperated by approximately delta_ft feet.
％ By default, delta_ft = 100 feet. All lat/lon inputs & outputs are in
％ degrees.
KML 2 SHP Converter for Points, lines and polygons
Extension for ArcView 3.x will convert KML files from Google Earth to ShapeFiles, adding a new field called “Name” in the shapefile attribute table, automatically storing the name entered on the “Google Earth – New” window.
We describe and demonstrate an algorithm that takes as input an
unorganized set of Points fx1 xng IR3 on or near an unknown
manifold M, and produces as output a simplicial surface that
approximates M. Neither the topology, the presence of boundaries,
nor the geometry of M are assumed to be known in advance — all
are inferred automatically from the data. This problem naturally
arises in a variety of practical situations such as range scanning
an object from multiple view Points, recovery of biological shapes
from two-dimensional slices, and interactive surface sketching.
