Gocator sensors support two types of transformation sources: Global or Current Configuration. The
choice for the transformation source depends on how the sensor will be used.
You can switch between these transformation sources at any time.
Source Description
Global transformation A single global transformation is applied to the laser
profile that is acquired, regardless of what configuration
is currently loaded on the sensor.
The global transformation is saved on the sensor in a
separate hidden file and is retained when the sensor is
reset or powered off.
Global transformation is typically used when the sensor
mounting is constant over time and between scans, e.g.
when the sensor is mounted in a permanent position
over a conveyor belt.
Current Configuration The transformation is associated with the current
configuration.
The transformation is saved with the same file name
as the current configuration (but with a different
extension). The transformation is accessible to the
user through the File Manager (see page 58).
When a configuration is loaded on the sensor, the
transformation is automatically loaded together with it.
Current Configuration is typically used when the
sensor’s position relative to the object scanned is always
changing, e.g. when the sensor is mounted on a robot
arm moving to different scanning locations.
