How to use the Point to Point Measurement tool
Click the Setup tab to use the setup for this tool.
General
1. Image: To use a different image source, click the Link button. The tool works only with greyscale
images.
Points
1. Point One Tab -Point One: You define the beginning measurement point on the Point One tab. You
can manually enter the X and Y coordinates of the point or click the Link button to link a point.
2. Point One Tab - Origin: When you link Point One, Setup will complete the Origin location, based on
the following order:
2a. If Point One’s link source property
contains "RWC" (it uses Real World Coordinates), the Origin is
set to (0, 0, 0) since Point One’s location is relative to those coordinates. The Origin Link button is
disabled.
2b. If Point One’s link source tool
has a Tool Origin property, the Origin is linked to it. The Origin Link
button is disabled.
2c. If Point One’s link source tool
does NOT have a Tool Origin property (e.g. the Data Instance tool),
the Origin is left unchanged. The Origin Link button is enabled. Click the Link button to link an Ori-
gin for Point One.
Point Two Origin The origin the tool will use when Point Two Origin Source is set to the
value Use Point Two Origin
Point Two The x and y coordinates of the ending measurement point
Distance Type Euclidean: Measure direct distance between the points
AbsoluteX: Measure the distance between Point One and a line through
Point Two's X coordinate and perpendicular to the X axis
AbsoluteY: Measure the distance between Point One and a line through
Point Two's Y coordinate and perpendicular to the Y axis
Tolerance If the distance between the two points is greater than this value, the tool
will fail. The parameters are minus, nominal, and plus.
Output Name What it is
Scale Factor The scale factor applied to the output distance. This is applied after any
camera calibration. (See“Scale Factor” on page 3-125.)
Scale Factor Train
Distance
When the tool is trained, this scale factor is calculated so that the mea-
sured distance is scaled to this value.
Distance The measured distance between Point One and Point Two
In Tolerance True if the Distance is within the tolerance range
Distance Error The difference between the Tolerance Nominal and the Distance
Line Segment The distance line segment.
