Out-of-Bounds Indices in Scene 12kitchen and Missing Annotations in Scene 13bathroom

by SizheZ - opened

Thank you for your excellent work and for providing this dataset! I encountered a couple of issues when trying to visualize the data:

Scene 12kitchen
In the annotations file (FunGraph3D.annotations.json), some indices exceed the total number of points (2,109,537).
Scene 13bathroom
There are no elements for this scene in FunGraph3D.annotations.json.

Below is the code I used to check each scene:

import json
from plyfile import PlyData
import trimesh

scene_names = [
    '0kitchen',  '1bathroom',  '2livingroom', '3kitchen',
    '4livingroom', '5kitchen',  '6kitchen',    '7bedroom',
    '8bathroom',  '9bedroom',   '10kitchen',   '11bedroom',
    '12kitchen',  '13bathroom'
]

with open("./FunGraph3D/FunGraph3D/FunGraph3D.annotations.json") as f:
    data = json.load(f)

for scene in scene_names:
    plydata = PlyData.read(f"./FunGraph3D/FunGraph3D/{scene}/{scene}.ply")
    n_header = plydata['vertex'].count
    print(scene, n_header)

    mesh = trimesh.load(f"./FunGraph3D/FunGraph3D/{scene}/{scene}.ply", process=False)
    
    scene_annos = [anno for anno in data if anno["scene_id"] == scene]
    print("This scene has", len(scene_annos), "items")
    
    for anno in scene_annos:
        if anno["indices"][-1] > n_header:
            print(anno["indices"][-1], ">", n_header)

Output:

13bathroom 1939755 
This scene has  0 items

I found that the "scene_id" in "FunGraph3D.annotations.json" are :

['0kitchen', '1bathroom', '2livingroom', '3kitchen', '4livingroom', '5kitchen', '7kitchen', '9bedroom', '10bathroom', '11bedroom', '12kitchen', '13bedroom', '14kitchen', '15bathroom', 'extra_lab']

While the dataset includes:

['0kitchen', '1bathroom', '2livingroom', '3kitchen', '4livingroom', '5kitchen', '6kitchen', '7bedroom','8bathroom', '9bedroom',  '10kitchen',  '11bedroom', '12kitchen',  '13bathroom']

After remapping the scene names, everything works correctly.
