Nuscenes的open3d可视化是一种基于Python的可视化工具,可用于展示Nuscenes数据集中的3D场景。下面是一个简单的例子:
1.首先,需要安装open3d库和nuscenes库:
```
pip install open3d nuscenes-devkit
```
2.导入必要的库:
```python
import open3d as o3d
from nuscenes.nuscenes import NuScenes
from nuscenes.utils.data_classes import LidarPointCloud
```
3.加载Nuscenes数据集:
```python
nusc = NuScenes(version='v1.0-mini', dataroot='/path/to/nuscenes')
scene = nusc.scene[0]
sample_token = scene['first_sample_token']
sample = nusc.get('sample', sample_token)
lidar_token = sample['data']['LIDAR_TOP']
lidar_data = nusc.get('lidar', lidar_token)
point_cloud = LidarPointCloud.from_file(nusc.get('lidar', lidar_token)['filename'])
```
4.将点云数据转换为open3d格式:
```python
pcd = o3d.geometry.PointCloud()
pcd.points = o3d.utility.Vector3dVector(point_cloud.points.T)
```
5.可视化点云:
```python
o3d.visualization.draw_geometries([pcd])
```
这将打开一个3D窗口,展示Nuscenes数据集中的第一个场景的点云。您可以使用鼠标旋转和缩放视角,以便更好地查看场景。
