class OpenLABELAnnotations(object): (source)

Annotations parsed from OpenLABEL format able to be converted to FiftyOne labels.

Method	`__init__`	Undocumented
Method	`get_dimensions`	Get the width and height of a given URI or file id
Method	`get_labels`	Get the FiftyOne labels corresponding to the annotations of a given URI. The results are two dictionaries, sample- and frame-level, mapping field names to values and label objects.
Method	`parse_labels`	Parses a single OpenLABEL labels file.

def get_dimensions(self, file_id): (source) ¶

Get the width and height of a given URI or file id

Parameters
file_id	the unique identifier to a media file
Returns
(width, height) of the given file

def get_labels(self, uri, label_types, frame_size, seg_type, skeleton=None, skeleton_key=None): (source) ¶

Get the FiftyOne labels corresponding to the annotations of a given URI. The results are two dictionaries, sample- and frame-level, mapping field names to values and label objects.

Parameters
uri	the unique identifier to a media file
label_types	a list of label types to load. The supported values are `("detections", "segmentations", "keypoints")`.
frame_size	the (width, height) tuple for the media frame
seg_type	the `SegmentationType` to use for segmentation annotations
skeleton:`None`	a `fiftyone.core.odm.dataset.KeypointSkeleton` to use as a reference when loading keypoints
skeleton_key:`None`	the name of the field in the OpenLABEL annotations containing the labels of keypoints matching the labels of the given skeleton
Returns
a dictionary of sample level fields and label objects and a dictionary of frame numbers to frame level fields and label objects

def parse_labels(self, base_dir, labels_path): (source) ¶

Parses a single OpenLABEL labels file.

Parameters
base_dir	path to the directory containing the labels file
labels_path	path to the labels json file
Returns
a list of potential file_ids that the parsed labels correspond to
