Tried to extract bbox from 'Rendered.ai' Dataset.

object_bbox_extraction_from_rendered_ai_dataset.py

from PIL import ImageDraw as D
from PIL import Image
from PIL import ImagePath
import json

with open('syn_sample/annotations/0000000000-1-Image-ana.json','r') as f:
    annotation = json.load(f)
i = Image.open("syn_sample/images/0000000000-1-Image.png")
draw = D.Draw(i)
objects = annotation['annotations']
for obj in objects:
    x,y,w,h = obj['bbox']
    draw.rectangle(((x,y), (x+w, y+h)), outline="white")
i.show()

bbox format is [originX, originY, width, height]

So solution would be:
for obj in objects:
x,y,w,h = obj['bbox']
draw.rectangle(((x,y), (x+w, y+h)), outline="white")

@3dhedges Thanks. It works!

Is it possible to get Rotated BBox?
