调研方向

打开 lyft_dataset_sdk/utils/geometry_utils.py,将 BoxVisibility 的 docstring 和注释与现有的 box_in_image docstring 进行比较。更新措辞,使可见性明确表示角点位于图像内,而不考虑遮挡,然后检查周围的文档以确保术语一致。

描述

documentation

Hey,

We have three levels of box visibility:

    """Enumerates the various level of box visibility in an image."""

    ALL = 0  # Requires all corners are inside the image.
    ANY = 1  # Requires at least one corner visible in the image.
    NONE = 2  # Requires no corners to be inside, i.e. box can be fully outside the image.

Notice how the description of ANY says "at least one corner visible in the image" and rest say "corners inside the image" This creates the confusion. As by visibility, people infer that the object should actually be visible in that particular image without occlusions.

Also, the docstring of box_in_image says

"""Check if a box is visible inside an image without accounting for occlusions.
...
...
   Returns: True if visibility condition is satisfied.
"""

Here it talks about "visible inside an image without accounting for occlusions". I think this clears the confusion, and BoxVisiblity should also explicitly mention this in its docstring. I propose new docstring and comments for BoxVisiblity class:

class BoxVisibility(IntEnum):
    """Enumerates the various level of box visibility inside an image without accounting for occlusions"""

    ALL = 0  # Requires all corners are visible inside the image.
    ANY = 1  # Requires at least one corner is visible inside the image.
    NONE = 2  # Requires no corners to be visible inside, i.e. box can be fully outside the image.

I would love to know your thoughts.
