The standard deviation and variance are measures of how spread out operands values
are. StdDev (Standard
Deviation) and
Variance
Use of Constants
In general, a user-defined constant can be selected as one of the Operands for the Math tool. This allows for
a number of things, including scaling the output of a vision tool in real units (by dividing that output by a known
conversion factor). Along the same lines, dynamic scaling of outputs is also possible by dividing one Operand
by another and then multiplying by a constant conversion factor. In this case, two Math tools would be used:
one set for Division, the other for Multiplication. The output of the first Math tool would be an Operand for the
second Math tool.
Results
The output of the math operation selected for the inputs is diplayed in the results area of the Math tool Input
tab.
Math Tool and the Remote Command Channel (RCC)
Description Syntax
Sets the specified tool operand, if it is a
constant. Value should be a floating number. set mathtool tool_name|tool_number operand_1|operand_2
Gets the value of the specified tool operand, if
it is a constant. get mathtool tool_name|tool_number operand_1|operand_2
7.4.4 Measure Tool
Measure tool can be used to measure distance, calculate angles, and create points and lines for use as inputs
to other Measure Tools.
There are three Measure Tool operations:
• Measure from a point to a point
• Intersect two lines
• Measure from a line to a point
• Measure a curve to a point
• Measure a curve to a line
In these operations, points are generated by a variety of vision tools and lines are created by other Measure
Tools.
Usage
• Determine the location of a Blob
