matlab读取点云文件

%matlab读取ply格式,效果较好，可以旋转

ptCloud = pcread("2111.ply"); % read from a PLY file
figure
pcshow(ptCloud);
title("Original Data");

%matlab 读取txt格式，不能旋转

clear;clc;
sig=importdata("tree.txt");
x=sig(:,1);
y=sig(:,2);
z=sig(:,3);

plot3(x, y, z,"k.","MarkerSize",1)
xlabel("X","Fontsize",13),ylabel("Y","Fontsize",13),zlabel("Z","Fontsize",13);
grid on

据说matlab2017a可以实现点云.ply--->.pcd格式的转换

ptCloud = pcread(‘0.ply’); % read from a PLY file
pcwrite(ptCloud,"0.pcd");
