mmcv.ops.nms_bev(boxes: torch.Tensor, scores: torch.Tensor, thresh: float, pre_max_size: Optional[int] = None, post_max_size: Optional[int] = None)torch.Tensor[源代码]

NMS function GPU implementation (for BEV boxes).

The overlap of two boxes for IoU calculation is defined as the exact overlapping area of the two boxes. In this function, one can also set pre_max_size and post_max_size.

参数
  • boxes (torch.Tensor) – Input boxes with the shape of (N, 5) ([x1, y1, x2, y2, ry]).

  • scores (torch.Tensor) – Scores of boxes with the shape of (N,).

  • thresh (float) – Overlap threshold of NMS.

  • pre_max_size (int, optional) – Max size of boxes before NMS. Default: None.

  • post_max_size (int, optional) – Max size of boxes after NMS. Default: None.

返回

Indexes after NMS.
