点云数据文件,ply格式
好的,我可以为您解答这个问题。首先,您需要确保已经安装了pyrealsense2库和其它依赖库。接下来,您可以按照以下步骤进行操作:
1. 导入所需的库:
```python
import pyrealsense2 as rs
import numpy as np
import open3d as o3d
```
2. 创建一个Realsense的pipeline对象:
```python
pipe = rs.pipeline()
config = rs.config()
config.enable_stream(rs.stream.depth, 640, 480, rs.format.z16, 30)
config.enable_stream(rs.stream.color, 640, 480, rs.format.bgr8, 30)
profile = pipe.start(config)
```
3. 循环读取Realsense的数据,保存点云到ply文件:
```python
try:
while True:
# Wait for a coherent pair of frames: depth and color
frames = pipe.wait_for_frames()
depth_frame = frames.get_depth_frame()
color_frame = frames.get_color_frame()
if not depth_frame or not color_frame:
continue
# Convert images to numpy arrays
depth_image = np.asanyarray(depth_frame.get_data())
color_image = np.asanyarray(color_frame.get_data())
# Create point cloud from depth image and color image
pc = rs.pointcloud()
points = pc.calculate(depth_frame)
pc.map_to(color_frame)
colors = np.asanyarray(color_frame.get_data())
verts = np.asanyarray(points.get_vertices())
pcd = o3d.geometry.PointCloud()
pcd.points = o3d.utility.Vector3dVector(verts)
pcd.colors = o3d.utility.Vector3dVector(colors.astype(np.float) / 255)
# Save point cloud to ply file
o3d.io.write_point_cloud("point_cloud.ply", pcd, write_ascii=True)
except KeyboardInterrupt:
pass
finally:
pipe.stop()
```
在上述代码中,我们使用了Open3D库来保存点云到ply文件,并且将颜色信息也保存在了文件中。您可以根据自己的需求修改保存文件的路径和文件名。此外,我们使用了try-except语句和KeyboardInterrupt异常来处理程序的退出。
