Impact Reference Guide Line Gauge Datum Line
3-127 Datalogic Automation Inc.
Datum Line Type The tool measures from the Wide Line ROI point: Absolute Distance to
Datum Line: the absolute distance to the Datum Line
Signed Distance to Datum Origin X Axis: the signed distance to the
Datum Origin’s X axis
Signed Distance to Datum Origin Y Axis: the signed distance to the
Datum Origin’s Y axis
Absolute Distance to Datum Origin X Axis: the absolute distance to the
Datum Origin’s X axis
Absolute Distance to Datum Origin Y Axis: the absolute distance to the
Datum Origin’s Y axis
Signed Distance to Datum Line: The Datum Line is treated as an origin X
axis. If the endpoint is below the datum line, then the reported distance is
positive. If the endpoint is above the line, then the reported distance is
negative.
Signed Distance to Tool Origin X Axis: the signed distance to the tool ori-
gin’s X axis
Signed Distance to Tool Origin Y Axis: the signed distance to the tool ori-
gin’s Y axis
Absolute Distance to Tool Origin X Axis: the absolute distance to the tool
origin’s X axis
Absolute Distance to Tool Origin Y Axis: the absolute distance to the tool
origin’s X axis
Distance Tolerance If the distance between the beginning and ending measurement points
exceeds this value, the tool will fail. The parameters are minus, nominal,
and plus.
Endpoint Position If Use Center is false, this is the found point to use for measuring (point
number one is at the beginning end of the Wide Line ROI)
Use Center If True, the measurement end point is half way between the Endpoint
Position, and the next point beyond it
Blob Color to Find Bright or Dark objects
Blob Threshold
Method
See “Grey Level Threshold Types” on page 3-68 for more details.
Fixed Blob Thresh-
old Percentage
The grey level threshold value for fixed single threshold types (in per-
centage)
Adaptive Blob
Threshold Offset
If Adaptive Threshold Method is selected, this offset is added to the
adaptive threshold. This allows you to weight the adaptive threshold up
or down.
Noise Level The amount of background noise present in the image. Higher noise
means the edges must be farther apart. Lower noise allows edges that
are closer together.
Maximum Number
of Edges To Find
Limits the number of edges found to those with the strongest transition
Edge Pattern The edge pattern to find (Rising indicates a transition from dark to light;
Falling indicates a transition from light to dark)
