This paper introduces a method to extract skeleton from RGB synthesized branch point cloud. You can use this procedure to extract skeleton from point cloud.

A quick video demo of the algorithm can be found here.

1. orchard segmentation

2. tree segmentation

• This procedure runs in win_x64.
• Currently, only ASCII encoded .ply file is supported, you can use other tools to convert point cloud formats, such as CloudCompare.
• The file path should not contain Chinese characters.
• The branch point cloud size should be less than 20k points.
• The branch point cloud needs to be claer and its shape should be radial.

You can obtain the sample point cloud data from the link.

This procedure and related data have been described in detail in the paper: "Zhang W, Peng X, Cui G, Wang H, Takata D, Guo W. Tree Branch Skeleton Extraction from Drone-Based Photogrammetric Point Cloud. Drones. 2023; 7(2):65. https://doi.org/10.3390/drones7020065 ”(https://www.mdpi.com/2504-446X/7/2/65).
