Setting Description
third-party software such as HexSight, Halcon, etc.
Padding Length Determines the amount of extra data on the Y axis from the surface surrounding the
detectedpart that will be included. This is mostly useful when processing part data with
third-party software such as HexSight, Halcon, etc.
Min Area Determines the minimum area for a detected part. Set this value to a reasonable
minimum in order to filter out small objects or noise.
Max Part Length Determines the maximum length of the part object. When the object exceeds the
maximum length, it is automatically separated into two parts. This is useful to break a
long object into multiple sections and perform measurements on each section.
Frame of Reference Determines the coordinate reference for surface measurements.
Sensor
When Frame of Reference is set to Sensor, the sensor's frame of reference is used.
The way the sensor's frame of reference is defined changes depending on the surface
generation Type setting ( see on page 113 for more information):
l
When parts are segmented from a continuous surface (the surface generation Type
setting is set to Continuous), measurement values are relative to a Yorigin at the
center of the part (the same as for Part frame of reference; see below).
l
When parts are segmented from other types of surfaces (the surface generation Type
setting is set to Fixed Length, Variable Length, or Rotational), measurement
values are relative to a Yorigin at the center of the surface from which the part is
segmented.
The Surface Bounding Box GlobalXand GlobalYmeasurements (see Bounding Box on
page 200) are exceptions:regardless of the Frame of Reference setting, these
measurements produce the Sensor frame of reference values of the Part frame of
reference origin (which is the bounding box center), except for GlobalY when parts are
segmented from continuous surfaces. In this case the GlobalY value is the Y value relative
to the encoder zero position. These values can be used to locate Part frame of reference
measurements in a world space.
Part
When Frame of Reference is set to Part, all measurements except Bounding Box X and
Y are relative to the center of the bounding box of the part. For Bounding Box X and Y,
the measurement values are always relative to the sensor frame of reference (see
Bounding Box on page 200).
Edge Filtering
See Edge Filtering on the next page.
To set up part detection:
1. Go to the Scan page and choose Surface in the Scan Mode panel.
If this mode is not selected, you will not be able to configure part detection.
