Share sample dataset

[datvuthanh]

Hi Rice,

1. Can you share one sample data (including image, mask and camera's calibration)? I cannot debug your source code.
2. How can I generate mask for each camera?

a = MultiCamDataset(
    index_file="../../openape/snapshots/out-mar23/index.txt",
    mask_dir="../../openape/masks",
    cameras=["main", "narrow", "fisheye", "leftpillar", "leftrepeater", "rightpillar", "rightrepeater", "backup"],
    cam_shape=(480, 640),
    nframes_per_point=5,
    limit_size=1000,
    dynamic=True,
)

Thank you very much!
