Hi.

I'm new to matlab. I did the following to edit point cloud data.

ptCloud=pcread(filename)
pcshow(ptCloud)

After editing, the data is saved as a FIG file, how can I convert it to a PCD file?

There is a function called pcwrite. The MATLAB documentation has a good article on it.

There are 1832 points in one point cloud.

You might want to change the colormap to highlight more of the points. There are a lot of dark blue points in the front right.

OH, I see.

fig = openfig('NameOfFig.fig'); outnamebase = "pcout_"; pcviewers = findobj(fig, 'tag', 'pcviewer'); for K = 1 : length(pcviewers) x = pcviewers(K).XData; y = pcviewers(K).YData; z = pcviewers(K).ZData; C = pcviewers(K).CData; xyz = [x(:),y(:),z(:)]; if size(C,2) == 1 ptc = pointCloud(xyz, 'Intensity', C); else ptc = pointCloud(xyz, 'Color', C); end outname = outnamebase + K + ".pcd"; pcwrite(ptc, outname); end

↑ I would like to know more about what each line of this code does.
