It's a long video but it really worth the time! I learned a lot of tools that I can use, not especially for creating a ground surface, but during your explaination, I realized that I can use them in my project too. You also shared the experience of parameters tunning with us, which saves me much time! Before this video, I was still manually segment the noise point out or using the simple sor filter. I've learned a lot! Thanks for the contribution!
Hi, thanks for your responses and guidance. I have a question. I followed all of the steps and finally when I wanted to save the data in the “las” format, in the “las/laz scale” window the “original resolution” is inactive and I have just the other two options “optimal resolution” and the “custom resolution” active, although in your video you chose the “original resolution”. Why is this happened for me and it is inactive? Does it effect if I choose the other two options on my results? Thanks for your response, Best regards, Amir Farshadfar
I just find this useful video i install cloud compare sw and follow the steps but the option CSF filter is not active so any one can advise how to make it it active(I do not have Civil3D)
@@The3rdDimensionSurveying cool thanks for the reply. And thanks for your great videos. They help a ton. I’m still new at this. Was using cloud compare and recently got metashape pro. I seem to be have troubles when importing my GCPs and use them for to optimize my cameras, my camera accuracies drop to 15m not sure what the heck I’m doing wrong. I’m using a Mavic 3E
Dear Thanks so much for your video and guidance. I have a question and I do not know if you can help or not. I used the CloudCompare software to import my drone data as the point cloud data and exported them into the ReCap software to create the rcp file format and then attached them into the Civil 3D software to import my data and used the “create surface” to create a surface using the “kriging” method and also the “NoFilter” option to create another surface and followed your video: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-QIwZhloTKes.html to create a “TIN volume surface” to compare my “kriging” and “NoFilter” surfaces with each others, like the mentioned video with the colored TIN volume surface, but when I adjusted the options like you, it showed me a surface many meters far from my data on the down of the my survey data! Could you please guide me what should I do and what is the problem? How should I solve it? Thanks for your guidance I look forward to hearing from you Sincerely Amir Farshadfar
I've never seen the surface creation filtering method shift a surface before which is what I think you are describing. It would be possible to see pockets of displacement between surfaces if there were holes in the point cloud based on filtering methods. If you send me a link containing your data I could take a look at it.
