How to train data for CANUPO correctly?
Hi, I would like to use CANUPO to classify my point cloud. Data has downed logs, shrubs, stems and grass. Canupo accepts only two training data at once, so first trained data will be the downed logs and the second should include all other type of objects (grass, stem and shrubs)? Please help. Thank ...

Re: RANSAC shape detection, detecting many cylinders.
Thank you so much, it worked after several attempts. Sorry I was in the field which is why I didn't respond. Segments are created now, but still not perfect. For instance one cylinder can include 2-3 segments, could you please tell me the way to improve it ? Also, I now have a lot of vertical and ho...

Re: Masking a point cloud with segmented point cloud?
Thanks, original point cloud has scalar fried value ranges from 1.0 to 1.0. Segmented cloud value ranges from 1 to 1097. I am not sure how to filter out segmented cloud from original cloud.

Masking a point cloud with segmented point cloud?
Hi Daniel,
I used PCL clustering algorithm to segment some features. Now I want to remove those segmented points from original point cloud. Is there a way to do it in CC?
Thanks in advance,
Kind regards,
Shukhrat

Re: Converting LAS file into PCD doesn't preserve coordinates?
Oh I see, Y coordinates rounded into 0 or 0.5 (6106507.6058830 is rounded into 6106507.5000000) when exporting from LAS into PCD which is why it causes those lines. Do you know how to resolve this problem?

Re: Converting LAS file into PCD doesn't preserve coordinates?
Hi Daniel, Sorry I am back to this question again. I need this LAS to PCD conversion in order to run PCL package. I tried to import LAS file with Global Shift "No" and it is converting into PCD by preserving coordinates. However, if I open PCD file in CC, point cloud turned into some strip...

Re: Converting LAS file into PCD doesn't preserve coordinates?
It doesn't look like that. Because, please look at the first attached image (prtscr1.jpeg), print screen from point cloud, it was taken by checking "Preserve global shift on save". As you can see it shows original (Xg, Yg, Zg) and local coordinates (XI, YI,ZI). If I export this file in PCD...

Re: Converting LAS file into PCD doesn't preserve coordinates?
Original point cloud has EPSG:28355. If I reject Global Shift while importing the point cloud, coordinates are changing into some local coordinates. And if I export into PCD, it doesn't restore original EPSG:28355 but saving local coordinates. I need original EPSG 28355 in output PCD file.
Thanks
Thanks

Re: Converting LAS file into PCD doesn't preserve coordinates?
Thanks for your quick reply Daniel. If I reject the 'Global Shift' as you suggested, projected coordinates are not imported at all which I won't be able to save them in PCD format. But I need projected coordinates for my analysis. Coordinates look like eg. X = 696056.000 Y = 6106512.000. Is there an...
