robokudo.io.cas_annotation_codecs¶

KRROOD-backed codecs for CAS annotation serialization.

Classes¶

`Open3DPointCloudJSONSerializer`	Serialize Open3D point clouds using base64-encoded PCD payloads.
`NumpyScalarJSONSerializer`	Serialize NumPy scalar values with dtype-preserving metadata.

`serialize_annotations`(...)	Serialize annotation objects with the KRROOD serializer.
`deserialize_annotations`(...)	Deserialize annotation payloads with optional constructor keyword arguments.
`krrood_to_json`(→ typing_extensions.Any)	Serialize an arbitrary value with KRROOD.
`krrood_from_json`(→ typing_extensions.Any)	Deserialize an arbitrary value with KRROOD.

class robokudo.io.cas_annotation_codecs.Open3DPointCloudJSONSerializer¶

Bases: krrood.adapters.json_serializer.ExternalClassJSONSerializer[robokudo.io.open3d_codec_utils.o3d.geometry.PointCloud]

Serialize Open3D point clouds using base64-encoded PCD payloads.

classmethod to_json(obj: robokudo.io.open3d_codec_utils.o3d.geometry.PointCloud) → typing_extensions.Dict[str, typing_extensions.Any]¶: Convert an Open3D point cloud into a JSON-compatible payload.

classmethod from_json(data: typing_extensions.Dict[str, typing_extensions.Any], clazz: type[robokudo.io.open3d_codec_utils.o3d.geometry.PointCloud], **kwargs: typing_extensions.Any) → robokudo.io.open3d_codec_utils.o3d.geometry.PointCloud¶: Restore an Open3D point cloud from a JSON payload.

class robokudo.io.cas_annotation_codecs.NumpyScalarJSONSerializer¶

Bases: krrood.adapters.json_serializer.ExternalClassJSONSerializer[numpy.generic]

Serialize NumPy scalar values with dtype-preserving metadata.

classmethod to_json(obj: numpy.generic) → typing_extensions.Dict[str, typing_extensions.Any]¶: Convert a NumPy scalar value to JSON-compatible data.

classmethod from_json(data: typing_extensions.Dict[str, typing_extensions.Any], clazz: type[numpy.generic], **kwargs: typing_extensions.Any) → typing_extensions.Any¶: Recreate a NumPy scalar value from serialized data.

robokudo.io.cas_annotation_codecs.serialize_annotations(annotations: typing_extensions.List[typing_extensions.Any]) → typing_extensions.List[typing_extensions.Dict[str, typing_extensions.Any]]¶: Serialize annotation objects with the KRROOD serializer.

robokudo.io.cas_annotation_codecs.deserialize_annotations(data: typing_extensions.Any, **kwargs: typing_extensions.Any) → typing_extensions.List[typing_extensions.Any]¶: Deserialize annotation payloads with optional constructor keyword arguments.

robokudo.io.cas_annotation_codecs.krrood_to_json(value: typing_extensions.Any) → typing_extensions.Any¶: Serialize an arbitrary value with KRROOD.

robokudo.io.cas_annotation_codecs.krrood_from_json(value: typing_extensions.Any, **kwargs: typing_extensions.Any) → typing_extensions.Any¶: Deserialize an arbitrary value with KRROOD.
