Surface reconstruction from point cloud is
the process which approximate or interpolate the surface from the point data
produced by laser range scanning system and also called reverse engineering.
This problem is very difficult because the point data don’t have any connection
information between points. So many methods have developed and each method has
both the advantage and the disadvantage. The methods can be classified into two
groups largely, i.e. explicit method. The first one connects points directly,
that is, interpolates points. And the second one approximates the underlying
surface of point data by implicit function.
There are many applications for this job, for
example, design for mechanical parts or medical appliance, restoration for
damaged artifacts, etc. So many methods have been developed and commercial
software market about this field is active and grows.
