1 year ago Hi, thank you very much for creating and maintaining this great application. I am having similar problem, related with the issue title.
I am trying to use 3D Forest application for Linux (ubuntu 22.4) to segment also a large point cloud from a forest parcel obtained with TLS. I was able to import the base cloud (.las), and also separate terrain from vegetation. In the automatic tree segmentation step, I set the parameters, the program start processing, until a moment that it closed. Here are the lines form the Terminal:
parametry - prefix: ID_ parametry - vegetace-rest: vegetation-rest parametry - input-vegetace: cloud_subtraction.pcd parametry - input-veliksot: 0.06 parametry - input-range: 0.75 parametry - input-multiplikator: 2 parametry - input-elementy: 150 parametry - input-typ: PCA parametry - input-distance from terrain: 1.8 thread vytvoren seg nastaveno connect nastaveno SegmentationOctree::createOctree() Tue May 9 15:38:06 2023 Segmentation::ccomputeDescriptor() Tue May 9 15:38:10 2023 intensityMin: 0 intensityMax: 66.6667 m_PCAValue: 50 SegmentationOctree::mergeClusters() Tue May 9 15:38:15 2023 SegmentationOctree::createComponents() Tue May 9 15:38:16 2023 SegmentationOctree::findNeighborElements() Tue May 9 15:38:16 2023 free(): double free detected in tcache 2 Abortado (`core' generado)
I probed with different point cloud and different set of parameters, and happened the same. The last two lines seem to be the error. I think the program crashes when it runs this function: findNeighborElements()
I wonder which could be the problem o some recomendation to solve? Thanks! Andrea

First of all, thank you of this great open source application.
I'm trying to use the 3D Forest application for Windows (version 0.52) to segment a large point cloud obtained from a TLS of a trees parcel. The point cloud is in a binary PCD format containing the 3D points with their intensity (X, Y, Z, I). Importation and separation of the terrain from the vegetation by octree went well, but the automatic tree segmentation crashes. I have try different parameter values, and point cloud sizes (from 47 million to 24 million of points), but the application keep crashing in most of the cases and I'm not able to test adequate parameter values. The application seems to crash in
SegmentationOctree::setTreeElements(), but it's not easy to confirm, because the console disappears immediately.To try to identify the problem, I have download (cloned) the code, but I was not able to resolve all the compilation problems. (I will open an issue for this compilation problem too).
