Matlab 显示追踪点云 PLY格式

用的matlab，可以用来显示文件夹下的所有ply点云。

path=strcat('E:\WorkDatas\argoverse-tracking\train1\dcdcd8b3-0ba1-3218-b2ea-7bb965aad3f0\lidar\');       %当前所在目录
file = dir(fullfile(path,'*.ply'));    %读取所有ply格式文件
filenames = {file.name}';

close all;
figure('units','normalized','outerposition',[0 0 1 1]);


for idx = 1 : filelength               %批处理
    filedir = strcat(path, filenames(idx));
    ptCloud=pcread(filedir{1});   %ply格式文件用pcread读取
   

    ptCX = ptCloud.Location(:,1);
    ptCY = ptCloud.Location(:,2);
    ptCZ = ptCloud.Location(:,3);

    c = ptCZ;%c表示对z轴进行着色
    scatter3(ptCX, ptCY, ptCZ,10,c,'.')
    
    xlim([-200 200]);%限制坐标轴范围
    ylim([-200 200]);
    zlim([0 100]);
    view([1,1,1]);
    
    pause(0.1)%调整两帧间延迟时间
    
end
