First of all, we must ensure that the xyz data dimension is n × 3, otherwise it will be converted by matrix operation, for example:
Data=[spotx;spoty;spotz]';%注意有求逆运算
Then convert it through the pcwrite function that comes with matlab. The 2016b version does not have this function, and the 2018a version needs to be installed.
Data＝single(Data)；
ptCloud = pointCloud(Data(:,1:3));
pcwrite(ptCloud, 'test.pcd', 'Encoding', 'ascii'); %将程序中的xyz数据写入pcd文件中
pc = pcread('test.pcd');
pcshow(pc); %显示点云If there is no accident, the .pcd file has been generated, you can find the file path in the directory window, mine is in the bin folder
