VI_ROS

VI_ROS package

This package is a Vegetation Indices generator tool using a Kinect sensor. It can be used to generate VI (Vegetation Indices) images and 3D point clouds of the environment for monitoring vegetation purposes. At the moment only NDVI VI is supported.

Prerequisites

This project was build with ROS Kinetic but should work on older ROS versions as well. In addition to that, this project depends on the ROS packages iai_kinect2, OpenCV_3.X and pcl_ros.

Installation

$ cd ~/catkin_ws
$ git https://github.com/CTTCGeoLab/VI_ROS.git src/ndvi
$ catkin_make --pkg ndvi

Configuration

Configuration parameters can be found at the ndvi_kinect.launch file.
