This DF represents the actual perception capabilities available to the transmitting ITS-S, offering additional (often dynamic) details to the information provided in the sensor information container.

 It shall include the following components:

Fields:

* _measurementDeltaTime_ of type [**DeltaTimeMilliSecondSigned**](ETSI-ITS-CDD.md#DeltaTimeMilliSecondSigned) <br>

  difference between the time of estimation of the perceived region and the reference time. Positive values indicates that the provided information refers to a point in time after the reference time.

* _perceivedRegionConfidence_ of type [**ConfidenceLevel**](ETSI-ITS-CDD.md#ConfidenceLevel) <br>

* _perceptionRegionConfidence_ of type [**ConfidenceLevel**](ETSI-ITS-CDD.md#ConfidenceLevel) <br>

  the perception confidence.

* _perceivedRegionShape_ of type [**Shape**](ETSI-ITS-CDD.md#Shape)  (WITH COMPONENTS{..., radial ABSENT, radialShapes ABSENT})<br>

  specification of the shape of the perceived region.

* _perceptionRegionShape_ of type [**Shape**](ETSI-ITS-CDD.md#Shape)  (WITH COMPONENTS{..., radial ABSENT, radialShapes ABSENT})<br>

  specification of the shape of the perception region.

* _shadowingApplies_ of type **BOOLEAN** <br>

  indicates if the standard shadowing approach applies to the described perceived region.

  indicates if the standard shadowing approach applies to the described perception region.

* _numberOfPerceivedObjects_ of type [**CardinalNumber1B**](ETSI-ITS-CDD.md#CardinalNumber1B)  OPTIONAL<br>

  the optional number of perceived objects contained in the perceived region specified in the component perceivedRegionShape. 

  the optional number of perceived objects contained in the perception region specified in the component perceptionRegionShape. 

* _perceivedObjectIds_ of type [**PerceivedObjectIds**](#PerceivedObjectIds)  OPTIONAL<br>

  the optional list of identifiers of the objects specified in the Perceived Object Container that are contained in the perceived region specified in the component perceivedRegionShape.
