IMO you'd better start isolating "easier" parts such as vegetation or ground and then classify the tower from the remaining point cloud.

Don't hesitate to send me a cloud sample if you want me to try (cloudcompare [at] danielgm.net).
how can i send you my test date?

Hi Bonnie,
Sadly I couldn't download the file through Baidu (the download process is very slow and it fails after a while).

Imo, the easiest way to explain the scale is "how close from the object you look at it and what general shape it has from it". When you have a scale of 5cm, you take a 5cm sphere part of the cloud and check if it looks like a line, a plane or something in 3D.
Hi Haowyr, I am also interested in reading your thesis chapter. Do you have another pdf version that allow us to copy the text into google translate so that non-french speakers can read it too ? Also can you provide us your thesis?
Thank you
