Gocator Line Profile Sensors: User Manual
Gocator Web Interface • 199
For each script output that is added, an index will be added to the Output drop-down and a unique ID
will be generated.
To remove a script output, click on the button next to it.
4. Click the Save button to save the script code.
If there is a mistake in the script syntax, the result will be shown as a "Invalid" with a red border in the
data viewer when you run the sensor.
Outputs from multiple measurement tools can be used as inputs to the script. A typical script would
take results from other measurement tools using the value and decision function, and output the result
using the output function. Stamp information, such as time and encoder stamps, are available in the
script, whereas the actual profile data is not. (The script engine is not powerful enough to process the
data itself.) Only one script can be created.
Surface Measurement
Surface measurement involves capturing a sequence of laser profiles, optionally identifying discrete
objects, and measuring properties of the surface or the objects, such as the volume of the object or the
height at a certain position of the object. All volumetric tools have the ability to operate either on the
entire surface or the full object, or within a region of interest at a certain position in relation to the
surface or an object.
Multiple measurements can be performed on the entire surface or each discrete object, limited only by
the available CPU resources.
The frame of reference for the coordinate system of the detected object can be set to Sensor or Part in
the Part Detection panel (see on page 117). This setting determines what coordinate system the region
of interest for a measurement is positioned in, as well as the coordinate reference used to output
measurement values.
For example, if you need to measure the average height in a certain location relative to the sensor's field
of view regardless of the objects passing under the sensor, the frame of reference should be set to
Sensor. This is typical in applications where a wide web of material is continuously scanned, such as
paper, rubber, fabrics, etc. If on the other hand you need to measure the average height in a certain
location of a scanned object, the frame of reference should be set to Part. This is typical in applications
where discrete objects pass under the sensor and specific locations on the objects need to be inspected.
