Janek posted a comment on discussion General Discussion about 3DForest
HI, problem with LAS file can be with its version - if you have las file version 1.4 try to downgrade it and import. Or problem can be also with project creation if you have some spaces in your path to project folder.

Hi Brandon, for data you can use my mail address j,trochta@gmail.com for data i prefer pcd file from project folder or las file. jan st 4. 3. 2020 v 1:18 odesílatel noreply@sourceforge.net napsal: Hi Jan, Thanks for the quick response. I think the terrain cloud I got was pretty accurate, but I see what you're saying about the single scan and leaf-on conditions being an issue. I tried running automatic segmentation on multi-scan veg clusters too, but got results similar to the single scan. Seems like...

And one more note. From your figure it seams that you are processing only one scan from plot. It has problem with variable point density near and far from scaner. so if you have only single scan setup try to cut far away points or merge more scans together for more uniform pointcloud. Jan

Hi Brandon, thanks for using our software. for segmentation input parameters seems to be the best parameters as average point distance and multiplicator depends on data quality - shadows on branches or stem. important is also terrain cloud, where you should remove all points that do not belong to terrain. For very large cloud we usually use tiles made by lastools. for example we divide 1 square kilometer inot tile with size of 25 m and do segmentation on those tiles, with such a big data you have...

Hi Felix, Thanks for using our software. Explanation of stem connection is hard to explain in words, but I try the best. If you imagine point for which you are looking for neighbors (lets name them as N), now you can test if they are connected together of if they are creating two separate parts. You can on attached figure. for point (red) you find points in its neighborhood (point in blue circle), now starts analyzing those point is they are all connected together or not.(green circle).

Hi, problem with terrain Is understory vegetation that can be solved increasing to 12 or 15 cm instead of 10. Better terrain segmentation can help also with vegetation segmentation.

Hi, that kind of strange problem. It may be caused by wrong type of cloud. please can you open in text editor your project file? (the file with name of your project and .3df extension). On the first line it shouild contain some information about project and other lines are just list of clouds in project, but it starts with type of the cloud (teren, vege, strom,ost,..) in menu "Tree" -> "Tree edit" you can edit only clouds with type "tree" or "strom" in "Vegetation" menu "maual vegetation segmentation"...
-
Basically it can be updated on two sides - CPU and RAM. Ram consumtion is big since whole cloud is loaded into merory so you can upgrade memory. And number of cores in CPU can also speed up computation since we use multiple cores programing. But I also use i7 CPU and it could be enough. I usually use las file about 1 Gb but also 3Gb can be ok for start process and maybe in few hours it will be done without need of merge tree from diferent tiles. Also not sure what version are you using. I just uploaded...

Hi, first sorry for not answering your mail. Double trunk trees can be separated only by manual editing tool. So it depends how many double trunks you have on plot. And for the second question.

Hi the resolution is as you said the length of the smallest cube.

And for the second question. I am not sure I understand. If you import pts file into 3DForest project, it display OK or not? Also check if you have only one point cloud in file or more clouds are present? It should work like this: import as base cloud / create terrain using octree method and two new clouds should be created. one with terrain points and one with the rest. Jan
