Point cloud segmentation

Tree segmentation from a point cloud

This is a basic implementation of the tree segmentation algorithm proposed in [1].

Usage

TreeSegmentation "src_datasource_name" (e.g. TreeSegmentation my_file.csv)

Description

The program takes a csv file containing a point cloud as input and outputs two .csv files containing the segmented points and derived tree attributes. The input csv should use a comma (,) as a separator without a header and have the following syntax:

x, y, z, classification

Where:

• x (double) : projected x-coordinate (no geographic coordinate)
• y (double) : projected y-coordinate (no geographic coordinate)
• z (double) : normalized point elevation
• classification (unsigned integer): unsigned integer representing the point classification
