可以将 colors = [[0, 0, 0] for i in range(len(lines))],将所有的颜色设置为黑色。然后再将 line_set.colors 赋值为 o3d.utility.Vector3dVector(colors)。修改后的代码如下:
```
def draw_bounding_box(pcd, label):
corners = get_box_corners(label)
lines = [[0,1],[1,2],[2,3],[3,0],[4,5],[5,6],[6,7],[7,4],[0,4],[1,5],[2,6],[3,7]]
colors = [[0, 0, 0] for i in range(len(lines))]
line_set = o3d.geometry.LineSet(points=o3d.utility.Vector3dVector(corners), lines=o3d.utility.Vector2iVector(lines))
line_set.colors = o3d.utility.Vector3dVector(colors)
pcd += line_set
return pcd
```

可以将colors修改为[[1, 1, 0] for i in range(len(lines))],即将红色和绿色的值都设为1,蓝色的值为0,表示黄色。修改后的代码如下:
```
def draw_bounding_box(pcd, label):
corners = get_box_corners(label)
lines = [[0,1],[1,2],[2,3],[3,0],[4,5],[5,6],[6,7],[7,4],[0,4],[1,5],[2,6],[3,7]]
colors = [[1, 1, 0] for i in range(len(lines))] # 将颜色修改为黄色
line_set = o3d.geometry.LineSet(points=o3d.utility.Vector3dVector(corners), lines=o3d.utility.Vector2iVector(lines))
line_set.colors = o3d.utility.Vector3dVector(colors)
pcd += line_set
return pcd
```
def draw_bounding_box(pcd, label): corners = get_box_corners(label) lines = [[0, 1], [1, 2], [2, 3], [3, 0], [4, 5], [5, 6], [6, 7], [7, 4], [0, 4], [1, 5], [2, 6], [3, 7]]
这段代码的作用是在点云数据中绘制一个包围盒(bounding box)来表示目标物体的位置和大小。其中,pcd是点云数据,label是目标物体的标签信息。函数中调用了get_box_corners函数来获取包围盒的8个顶点坐标,然后通过lines数组来定义包围盒的12条边线段,最后可以使用绘图库如Matplotlib或Open3D来将这些线段绘制出来。
