PointcloudEpisodeTag

class PointcloudEpisodeTag[source]

Bases: supervisely.video_annotation.video_tag.VideoTag

PointcloudEpisodeTag object for PointcloudEpisodeAnnotation. PointcloudEpisodeTag object is immutable.

Parameters
meta : TagMeta

General information about point cloud episodes Tag.

value : Optional[Union[str, int, float]]

point cloud episodes Tag value. Depends on TagValueType of TagMeta.

frame_range : Tuple[int, int] or List[int, int], optional

point cloud episodes Tag frame range.

key : uuid.UUID, optional

uuid.UUID object.

sly_id : int, optional

PointcloudEpisodeTag ID in Supervisely.

labeler_login : str, optional

Login of user who created PointcloudEpisodeTag.

updated_at : str, optional

Date and Time when PointcloudEpisodeTag was modified last. Date Format: Year:Month:Day:Hour:Minute:Seconds. Example: ‘2021-01-22T19:37:50.158Z’.

created_at : str, optional

Date and Time when PointcloudEpisodeTag was created. Date Format is the same as in “updated_at” parameter.

Usage example
import supervisely as sly

meta_car = sly.TagMeta('car', sly.TagValueType.NONE)
# Now we can create a VideoTag using our TagMeta
tag_car = sly.PointcloudEpisodeTag(meta_car)
# When you are creating a new Tag
# Tag.value is automatically cross-checked against your TagMeta value type to make sure the value is valid.
# If we now try to add a value to our newly created Tag, we receive "ValueError", because our TagMeta value type is "NONE"
tag_car = sly.PointcloudEpisodeTag(meta_car, value="Bus")
# Output: ValueError: Tag car can not have value Bus

# Let's create another Tag with a string value type and frame range
meta_car = sly.TagMeta('cat', sly.TagValueType.ANY_STRING)
tag_car = sly.PointcloudEpisodeTag(meta_car, value="red", frame_range=(5, 10))

# Now let's create a Tag using TagMeta with "ONEOF_STRING" value type
# In order to use "oneof_string value type", you must initialize a variable with possible values(see class TagMeta for more information)
colors = ["brown", "white", "black", "red", "chocolate", "gold", "grey"]
meta_car_color = sly.TagMeta('car color', sly.TagValueType.ONEOF_STRING, possible_values=colors)
tag_car_color = sly.PointcloudEpisodeTag(meta_car_color, value="white", frame_range=(15, 20))

# If given value is not in a list of possible Tags, ValueError will be raised
tag_car_color = sly.PointcloudEpisodeTag(meta_car_color, value="yellow")
# Output: ValueError: Tag car color can not have value yellow
