This is an implementation of submitted 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, 65. https://doi.org/10.3390/drones7020065

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.

Video demo

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

point cloud data pre-processing video demo

1. orchard segmentation

2. tree segmentation

Restrictions

• 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.

Data and software avaible

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