open3d.ml.tf.vis.BoundingBox3D

class open3d.ml.tf.vis.BoundingBox3D(center, front, up, left, size, label_class, confidence, meta=None, show_class=False, show_confidence=False, show_meta=None, identifier=None, arrow_length=1.0)

Class that defines an axially-oriented bounding box.

__init__(center, front, up, left, size, label_class, confidence, meta=None, show_class=False, show_confidence=False, show_meta=None, identifier=None, arrow_length=1.0)

Creates a bounding box. Front, up, left define the axis of the box and must be normalized and mutually orthogonal.

center: (x, y, z) that defines the center of the box front: normalized (i, j, k) that defines the front direction of the box up: normalized (i, j, k) that defines the up direction of the box left: normalized (i, j, k) that defines the left direction of the box size: (width, height, depth) that defines the size of the box, as

measured from edge to edge

label_class: integer specifying the classification label. If an LUT is

specified in create_lines() this will be used to determine the color of the box.

confidence: confidence level of the box meta: a user-defined string (optional) show_class: displays the class label in text near the box (optional) show_confidence: displays the confidence value in text near the box

(optional)

show_meta: displays the meta string in text near the box (optional) identifier: a unique integer that defines the id for the box (optional,

will be generated if not provided)

arrow_length: the length of the arrow in the front_direct. Set to zero

to disable the arrow (optional)

static create_lines(boxes, lut=None)

Creates and returns an open3d.geometry.LineSet that can be used to render the boxes.

boxes: the list of bounding boxes lut: a ml3d.vis.LabelLUT that is used to look up the color based on the

label_class argument of the BoundingBox3D constructor. If not provided, a color of 50% grey will be used. (optional)
