About Using a Dynamic Reference Frame with 3DCreator Probes
3DCreator devices support the use of a Dynamic Reference Frame when capturing data. A DRF is an auxiliary piece of hardware with a configuration of infrared emitters, similar to a probe. Unlike a probe, DRFs are meant to be situated in a static relationship to the part being measured. DRFs establish a localized coordinate system that is independent of the camera position. This allows you to generate a stable coordinate system, related to the part being measured, even if the camera is being moved. DRFs are associated with probes and controlled by the individual probe definitions.
RevWorks sees the location information supplied by the 3DCreator when a DRF is used as raw device coordinates. Alignments you specify with the Alignment Manager may be used with or without the presence of a DRF.
The major benefit of a DRF is that you can establish a stable coordinate system that is statically related to your part, even if the camera array is being moved. The disadvantage is that data gathered when a DRF is employed is less accurate than data gathered without the use of a DRF. When not using a DRF, the 3DCreator camera array must be securely fixed and static relative to your part.
