Read and write PCL .pcd files in python

Reason this release was yanked:

This release is broken on some python versions.

Project description

pypcd4

Description

pypcd4 is a modern reimagining of the original pypcd library, offering enhanced capabilities and performance for working with Point Cloud Data (PCD) files.

This library builds upon the foundation laid by the original pypcd while incorporating modern Python3 syntax and methodologies to provide a more efficient and user-friendly experience.

Install

You can install pypcd4 via pip,

pip install pypcd4

How to use

Import pypcd4

from pypcd4 import PointCloud

Read from .pcd file

pc: PointCloud = PointCloud.from_path("xyzi.pcd")

PointCloud -> NumPy array

array: np.ndarray = pc.numpy()

array.shape
# (1000, 4)

NumPy array -> PointCloud

# Depends on number of features of your array

# If PointXYZI,
pc = PointCloud.from_xyzi_points(array)

# If PointXYZL,
pc = PointCloud.from_xyzl_points(array, label_type=np.uint32)

Create custom conversion method

If you cannot find preferred point type in pre-defined conversion methods, you can create it easily like,

fields = ("x", "y", "z", "intensity", "new_field")
types = (np.float32, np.float32, np.float32, np.float32, np.float64)

pc = PointCloud.from_points(array, fields, types)

Save as .pcd file

pc.save("nice_point_cloud.pcd")

License

The library was rewritten and does not borrow any code from the original pypcd library. Since it was heavily inspired by the original author's work, we extend his original BSD 3-Clause License and include his Copyright notice.
