以下是一个计算三维IoU的Python代码示例:
```python
def iou_3d(box1, box2):
"""
Compute the 3D Intersection over Union (IoU) between two 3D bounding boxes.
"""
# Compute box1 volume
box1_volume = (box1[3] - box1[0]) * (box1[4] - box1[1]) * (box1[5] - box1[2])
# Compute box2 volume
box2_volume = (box2[3] - box2[0]) * (box2[4] - box2[1]) * (box2[5] - box2[2])
# Compute intersection volume
intersection = [max(box1[0], box2[0]), max(box1[1], box2[1]), max(box1[2], box2[2]), min(box1[3], box2[3]), min(box1[4], box2[4]), min(box1[5], box2[5])]
if intersection[0] >= intersection[3] or intersection[1] >= intersection[4] or intersection[2] >= intersection[5]:
return 0.0 # No overlap
intersection_volume = (intersection[3] - intersection[0]) * (intersection[4] - intersection[1]) * (intersection[5] - intersection[2])
# Compute union volume
union_volume = box1_volume + box2_volume - intersection_volume
# Compute IoU
iou = intersection_volume / union_volume
return iou
```
