3. Point One Tab - Measurement Type: Select how you want the tool to measure the distance between
the points.
Euclidean: Measures the direct distance between the points
AbsoluteX: Measures the distance between Point One and a line that runs through Point Two's X
coordinate and is perpendicular to the X axis
AbsoluteY: Measures the distance between Point One and a line that runs through Point Two's Y
coordinate and is perpendicular to the Y axis
4. Point Two Tab - Point Two: You define the ending measurement point on Point Two tab. Manually
enter the X and Y coordinates of the point or click the Link button to link a point.
5. Point Two Tab - Origin: When you link Point Two, Setup will complete the Origin location, based on
the following order:
5a. If Point Two’s link source property
contains "RWC" (it uses Real World Coordinates), the Origin is
set to (0, 0, 0) since Point Two’s location is relative to those coordinates. The Origin Link button is
disabled.
5b. If Point Two’s link source tool
has a Tool Origin property, the Origin is linked to it. The Origin Link
button is disabled.
5c. If Point Two’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 Two.
Pass/Fail
1. Train the Scale Factor: The tool can be calibrated so that the distance measured in pixels on the image
relates correctly to the measurement’s real-world units. For example, you run the tool and the Mea-
surement Length displayed is 100, but the distance in the real world is 200. Enter 200 in the Train
Measurement Length field and click Train. The tool will calculates the Scale Factor so that the mea-
sured distance in pixels (the Measurement Length) equals the Train Measurement Length. The Scale
Factor is applied after any camera calibration factor. The Reset button resets the Measurement Length
and Scale Factor to their original values.
