Description: BMyCrust take as input a 3D scatter points cloud and return a tight, manifold, triangulation.
Remember that crust algorithm needs a cloud representing a volume, so open surface may give inaccurate results. For example : a plane can not be triangulated, half-sphere is in doubt, a sphere with a small hole shoud be good.
The more points are given the best the surface will be fitted, of course in this case you would have to wait more and in the worst case a memory help error may occurs. The best results are obtained with more points in high curvature feature.
The old version did not ensure the output surface to be a manifold so it could be used only for graphical purpose. In the new one a tight, regular manifold is returned. It as outward normals orientation, after using this algorithm is very easy to get an STL file from a point cloud.
I added a manifold extraction tool that also correct the errors (slivers) generated by delaunayn during the initial tessellation.-BMyCrust take as input a 3D scatter points cloud and return a tight, manifold, triangulation.

Description: With the rapid development of remote sensing technology, three dimensional coordinates and intensity information of observation
target can be obtained directly from LIDAR system. It is one of the important issues in the study on LIDAR data processing that
how to extract the object from the point cloud data captured by laser scanning effectively without the help of spectral information as
well as other auxiliary data. In this paper, a method for the target extraction from the point cloud data in the absence of other
auxiliary data is proposed. Experiment results indicate that the mentioned method can extract interesting object points from LIDAR
point cloud data powerfully.

Description: The Makefile is for MacOS X 10.6. The scanner is int 3Dscanner.cpp and uses OpenCV. he "ducky" subdirectory holds a set of test images. There are a couple of example .txt point cloud files included in the top-level directory (shrek-16.txt, ducky-points.txt, LPS-points.txt). The grabframes.{py.cpp} utility uses OpenCV to capture frames: hit c to capture "calib.jpg" and " " to capture scanner frames. You ll need to find the calibration target correspondences using Gimp or similar tool, and edit these into 3Dscanner.cpp. Be sure to se-The Makefile is for MacOS X 10.6.
