    Note:
        The box is bottom centered, i.e. the relative position of origin in the

        tensor (Tensor or np.ndarray or Sequence[Sequence[float]]): The boxes
            data with shape (N, box_dim).
        box_dim (int): Number of the dimension of a box. Each row is

        with_yaw (bool): Whether the box is with yaw rotation. If False, the
            value of yaw will be set to 0 as minmax boxes. Defaults to True.
        origin (Tuple[float]): Relative position of the box origin.
            Defaults to (0.5, 0.5, 0). This will guide the box be converted to
