Class ObjectTrackingAnnotation (2.13.2)

ObjectTrackingAnnotation(mapping=None, *, ignore_unknown_fields=False, **kwargs)

Annotations corresponding to one tracked object.

This message has oneof_ fields (mutually exclusive fields). For each oneof, at most one member field can be set at the same time. Setting any member of the oneof automatically clears all other members.

.. _oneof:


Non-streaming batch mode ONLY. Each object track corresponds to one video segment where it appears. This field is a member of oneof_ track_info.
track_id int
Streaming mode ONLY. In streaming mode, we do not know the end time of a tracked object before it is completed. Hence, there is no VideoSegment info returned. Instead, we provide a unique identifiable integer track_id so that the customers can correlate the results of the ongoing ObjectTrackAnnotation of the same track_id over time. This field is a member of oneof_ track_info.
Entity to specify the object category that this track is labeled as.
confidence float
Object category's labeling confidence of this track.
frames MutableSequence[]
Information corresponding to all frames where this object track appears. Non-streaming batch mode: it may be one or multiple ObjectTrackingFrame messages in frames. Streaming mode: it can only be one ObjectTrackingFrame message in frames.
