Description
mass, Top, Butt
center)
of mass of a hill, Top – the highest point, Butt center - a middle point
between two joining surfaces.
Circle criterion
0.1
The maximum value of the circle quality, with which a profile will be
defined as a circle. The circle quality = the standard deviation of the
profile points from the circle / circle radius. The range of values: 0..1
(the higher the value, the "worse" the circle). The "0" value is
supposed to be set for detecting a perfect circle.

Cut-Off border state
Off
Enable / Disable the border, beyond which the found points are not
valid.
Cut-Off border range,
%
5
The size of the cut-off border. This parameter specifies a percentage
of reducing the range of valid values.
Search distance
15
The distance from the previous point, within which the emergence of a
new point is valid. Unit of measurement - millimeters.
Invalid sequence
20
The number of invalid points. The points are considered invalid if the
distance between these points is greater than the "Search distance".
After the end of the invalid sequence, a new point will be taken as
valid.
Search range
1.5
The tolerance for the "X coordinate" parameter. Unit of measurement -
millimeters.
3D offset Х
0
3D offset of one point selected in the "Select" tab. These parameters
are applied only for the Riftek P2 protocol.
3D offset Y
0
3D offset Z
0
2D offset Х
0
2D offset of all points selected in the "Select" tab. These parameters
are applied for all protocols.
2D offset Z
0
* The scanner obtains a profile as a set of points. When searching for a template in
a profile, the software combines points into contour lines in accordance with the rules
described in the Table below.
Rule
Description
Maximum distance
between points
This rule sets the maximum distance between points along Z axis. If the distance
between points is less than this value, these points will be taken as one contour
line.
Unit of measurement - millimeters. An example of splitting the profile into
contour lines:
Maximum line half-
width
This rule sets the maximum distance from a point to a line. If the distance is less
than this value, the point will be considered belonging to this line. Unit of
measurement - millimeters.
Minimum line length
This rule sets the minimum length of the line. All lines, which less than this value,
will be considered as a noise, and will be cut off. Unit of measurement - millimeters.
