24.2.1.3. Clarification of approximating line segments and arcs
This stage includes the precise determination of the coordinates of the beginning
and end of the line segments that approximate the profile, and the coordinates of the
intersections of the segments. This stage does not contain any parameters.
Approximation is disabled - the beginning of the line
segment lies at the first point of the profile, which
does not allow accurate approximation of all points
Approximation is enabled - the beginning of the line
segment is recalculated taking into account the first
point of the profile and the optimal approximation of
all points of the profile
Approximation is disabled - the intersection of the
line segments forming the angle lies on the profile
point and is displaced relative to the true vertex of the
angle
Approximation is enabled - the intersection of the line
segments forming the angle is recalculated and lies
on the extension of the sides of the angle, which
corresponds to the true vertex of the angle
24.2.2. Stage 2. Building a graph
Upon completion of the profile approximation procedure, it is necessary to build a
computational graph.
The computation graph is a set of blocks and connections between them. It is
recommended (but not necessary) to orient the graph horizontally - smart blocks that extract
features from the profile (points, line segments, etc.) are placed on the left. Processing
blocks are placed in the middle. On the right are blocks for transmitting measurement
results to external systems and receiving messages from external systems.
In the current revision of the firmware, it is possible to save only one graph in the
internal memory of the scanner - it is the basic graph, which is loaded when you turn on the
scanner and starts working automatically. The graph can be saved to a computer for use in
other scanners of the “Smart” series or for use in the future, i.e. the saved graph can be
loaded into the scanner as a basic one.
The graph building area also displays the time (in microseconds) spent on profile
approximation and graph rendering. If this time is less than 1/(frequency of profiles in
seconds), each profile is processed, if greater - some profiles may be skipped and not
processed.
