Annotation System

The UnrealCV Dev For UnrealZoo annotation commands apply semantic labels to actors or to the complete world. They support segmentation and object-detection capture workflows.

Python API

• annotate_object(actor_name)

• annotate_world()

• clear_world_annotation()

• set_annotation_cache_enabled(enabled)

• clear_annotation_cache()

import unrealcv

client = unrealcv.Client('127.0.0.1', 9000)
client.annotate_object('Chair_01')
client.annotate_world()
client.set_annotation_cache_enabled(True)
client.clear_annotation_cache()
client.clear_world_annotation()

Use the cache when the same semantic setup is reused across many frames. Clear the cache after changing actor labels or material metadata.
