paralleldomain.model.annotation.polygon_3d

class Polygon3D(lines, class_id, instance_id=-1, attributes=<factory>)

A closed polygon made a collection of 3D Lines.

Parameters:

• lines (List[Line3DBaseGeometry[TypeVar(T, int, float)]]) – Polygon3D.lines

• class_id (int) – Polygon3D.class_id

• instance_id (int) – Polygon3D.instance_id

• attributes (Dict[str, Any]) – Polygon3D.attributes

lines

Ordered list of Line3D instances

class_id

Class ID of the polygon. Can be used to lookup more details in ClassMap.

instance_id

Instance ID of annotated object. Can be used to cross-reference with other instance annotation types, e.g., InstanceSegmentation3D or InstanceSegmentation3D. If unknown defaults to -1.

attributes

Dictionary of arbitrary object attributes.

to_numpy()

Returns all ordered vertices as a numpy array of shape (N x 3).

property length

Returns the length of the line.

class Polygons3D(polygons)

Collection of 3D Polygons

Parameters:

polygons (List[Polygon3D]) – Polygons3D.polygons

polygons

Ordered list of Polygon3D instances
