24.2. Creating a Smart function
The Smart function is created in two stages:
Stage 1 - Profile approximation.
Stage 2 - Building a graph.
24.2.1. Stage 1. Profile approximation
Profile approximation is the first stage in configuring the smart function of the
scanner. The "Profile Approximation" tab provides access to the parameters of the profile
approximation algorithm. The stability and accuracy of the measurement results directly
depend on the quality of the approximation. The optimal approximation is achieved when
each straight line on the profile forms a segment, not a broken line, and a circle (arc) is
approximated by a circular arc. In difficult cases, when the profile features do not allow
approximating a circle with an arc with sufficient accuracy, approximation by a set of
segments is possible, followed by approximation by a circle with a special smart block.
To perform the approximation, it is necessary to place a sample of the controlled
object in the scanner's field of view and achieve the required profile quality in accordance
with the procedures described in Section
The profile approximation algorithm can be divided into three sequentially
performed stages:
1. Splitting the entire set of profile points into fragments.
2. Splitting each fragment into a set of approximating line segments and arcs.
3. Clarification of approximating line segments and arcs.
