Visualizing the 3D bounding boxes created by BasicWriter

How can I visualize the 3D bounding boxes created by BasicWriter in Replicator?

The question has been asked before but I couldn’t reply to it.

Visualization Bounding Box Image using script for offline generation replicator

Hi @jiehanw I solved the issue. I used replicator generated bbox .npy data. In the tutorial, it was written like this: def colorize_bbox_2d(rgb_path, data, id_to_labels, file_path): rgb_img = Image.open(rgb_path) colors = [data_to_colour(bbox["semanticId"]) for bbox in data] fig, ax = plt.subplots(figsize=(10, 10)) ax.imshow(rgb_img) for bbox_2d, color, index in zip(data, colors, range(len(data))): #this one is the issue labels = id_to_labels[str(index)] r…

Here are the files we have:

bounding_box_3d_0020.npy

and

bounding_box_3d_labels_0020.json

The visualization documentation only includes 2D bounding box visualization:
