24.2.1.1. Splitting profile points into fragments
The procedure of splitting into fragments is intended to combine the points
belonging to one surface, but separated by random outliers or features of the scanned
object. At this stage, the profile fragments containing less than a specified number of points
are excluded from further processing.
The following parameters from Profile segmentation section affect the splitting
results:
·
Minimum size, points - the minimum required number of points in a profile
fragment for its participation in further processing.
·
Divide threshold, mm - the minimum distance in millimeters between two
successive profile points (left to right) required to combine these points into a
single fragment.
The splitting is done automatically by manipulating the specified parameters. The
control of merging the points into fragments is carried out visually according to the results of
approximating the profile by segments. Namely, if the ends of successive segments are not
connected, then they belong to different contours. Examples:
Source profile The profile is split into 1 fragments - all segments are
connected
The profile is split into 2 fragments - the contour from
above consists of one segment, and the contour from
below consists of 10 segments (the shortest one
forms the apex of the triangle)
The profile is split into 5 fragments (the shortest one
forms the apex of the triangle)
