whose decision you need to configure.
If one of these modes is not selected, tools will not be available in the Measure panel.
3. Expand the Sensor panel by clicking on the panel header.
4. Click the button corresponding to the sensor you want to configure.
The button is labeled Top , Bottom , Top-Left , or Top-Right , depending on the system.
Transformations can be configured separately for each sensor.
5. Expand the Transformations area by clicking on the expand button .
See the table above for more information.
6. Set the parameter values.
See the table above for more information.
7. Save the job in the Toolbar by clicking the Save button .
8. Check that the transformation settings are applied correctly after profiling is restarted.
Exposure
Exposure determines the duration of camera and laser on-time. Longer exposures can be helpful to
detect laser signals on dark or distant surfaces, but increasing exposure time decreases the maximum
speed. Different target surfaces may require different exposures for optimal results. Gocator sensors
provide three exposure modes for the flexibility needed to scan different types of target surfaces.
Exposure Mode Description
Single Uses a single exposure for all objects. Used when the surface is uniform and is the same for
all targets.
Dynamic Automatically adjusts the exposure after each frame. Used when the target surface varies
between scans.
Multiple Uses multiple exposures to create a single profile. Used when the target surface has a varying
reflectance within a single profile (e.g., white and black).
Video mode lets you see how the laser line appears on the camera and identify any stray light or
ambient light problems. When exposure is tuned correctly, the laser should be clearly visible along the
entire length of the viewer. If it is too dim, increase the exposure value; if it is too bright decrease
exposure value.
Under-exposure:
Laser line is not detected.
Increase the exposure value.
Over-exposure:
Laser line is too bright.
Decrease the exposure value.
