WebSep 2, 2024 · CloudCompare can use the other approach, that the terrain is seen from "below". The results are also only good if the parameters are correct. Perhaps; Please explain why. Looking at the simple illustration of how the algorithm selects the surface seems to find the more accurate "ground" between dense trees, for example. WebThe detailed classification parameters are described in Table 3. To speed up the computing time, we selected 5000-8000 points as a sub-sample (core points) (Table 3) for the local neighbourhoods...
