ply-file-format

问题 I've a .ply format model and trying to create a .pcd file one. After checking how .pcd format should look like and writing some code to convert it to .pcd format, my results are that the model is black colored only, instead of multi-colored like the .ply format model. In the .ply format there are 7 parameters in every point line (x,y,z,r,g,b,a) and on .pcd one it should be (x y z rgb). I'm not sure how to evaluate the rgb from the .ply file. Here's some of my .ply file data: ply format ascii

问题 I have a 3D point cloud each with different color/values attribute attached to each vertex of XYZ points. The Raw data is in simple .txt / csv form in columns i.e x, y, z, V1, V2, V3 and a new line for next point I am trying to use .ply to make images. I want to create a 3D image such as: . What is the appropriate code in ply format to color each surface or vertex based on each of these values? I want to create multiple maps with the same shape but mapping different colors to the surface. 回答1

问题 I am working with a project that requires accessing point cloud data in the form of .ply files and converting them into numpy arrays for running a deep learning algorithm. When I try to access my .ply files from my directory, I get the error "ValueError: two properties with same name" The following is my code - import glob import numpy as np from plyfile import PlyData, PlyElement arr = np.array([]) for filepath in glob.iglob('/content/drive/My Drive/PLY Files/*.ply'): plyFile = PlyData.read

问题 I have 3d point cloud data as .npy file and .pts data. To use these data for 3d classification neural net, I have to change these data to .h5 file. So, first I am trying to convert .npy or .pts file to .ply file using python. Could you refer to me example codes or help me for converting file format? Also, I will really appreciate for ways to convert .ply to .h5 format.. Sorry for my poor english skills. 回答1: I hope this code will get you started, it shows how to create a h5 file from a npy
