Banner PresencePLUS Pro COLOR—PROII Camera - Manual (Page 281)

The Measure tool window to the left shows the settings and results of the inspection to the right.
In the Inspection image, the center point of BLOB_1 and the nearest point in the input line MT_1 define the dashed
red line that runs from bottom left to top right. The actual measured distance between BLOB_1 and MT_1 is labeled
MT_2. The solid red triangle shows where MT_1 and MT_2 intersect. The Results section of the Measure Tool window
lists the distance between the intersection point and the Blob midpoint as 197.55 pixels.
The two shorter dashed lines represent the x- and y-components. The angle between MT_2 and the horizontal plane
is the curved counterclockwise arrow. In the Results section of the Measure Tool window, this angle is listed as -36.89
degrees.
Measurement Type
The PresencePLUS software can perform all three Measure tool operations using the default Absolute type or the
alternate Relative type. The types differ in how the Rotation Enable feature of a one of the Location tools—Locate,
Geometric Find, and Pattern Find—affect the Measure tool.
Absolute
When the measurement type is set to Absolute, the x- and y-components of the measured distance use the absolute, or
fi
xed, coordinate system of the camera’s field of view (FOV). If a rotation enabled Location tool precedes the Measure
tool in the order of operation (that is, if the Location tool is to the left of the Measure tool in the Navigation/Results
window), then the x- and ycomponent values and the angle of the line change as rotation occurs.
