Python如何从点云数据中提取x,y,z (How to unpack point data into x,y,z)

Problem:

Have PointsData as numpy array, with row as point, and column x, y, z

PointsData.shape

(9483,3)

How to extract x,y,z coordinate as vectors, this is useful using argmax to find point index with max value.

Solution:

x,y,z = PointsData.T

就是将Nx3的矩阵，转置成3xN的矩阵，然后unpack分别给x,y,z
