要修改点云的颜色,可以通过以下步骤使用 open3d 库:
1. 加载点云文件:
```python
import open3d as o3d
pcd = o3d.io.read_point_cloud("path/to/pointcloud.ply")
```
2. 创建自定义颜色:
```python
import numpy as np
# 随机生成颜色数组
colors = np.random.uniform(0, 1, size=(pcd.points.shape[0], 3))
```
3. 将颜色应用到点云:
```python
pcd.colors = o3d.utility.Vector3dVector(colors)
```
4. 可视化修改后的点云:
```python
o3d.visualization.draw_geometries([pcd])
```
完整示例代码:
```python
import open3d as o3d
import numpy as np
# 加载点云文件
pcd = o3d.io.read_point_cloud("path/to/pointcloud.ply")
# 随机生成颜色数组
colors = np.random.uniform(0, 1, size=(pcd.points.shape[0], 3))
# 将颜色应用到点云
pcd.colors = o3d.utility.Vector3dVector(colors)
# 可视化修改后的点云
o3d.visualization.draw_geometries([pcd])
```
运行后将会显示修改后的点云。
