New ROS package build instructions

1. Follow steps 1. to 3. of the normal instructions

2. Put the package in a catkin workspace

3. Build package with catkin

4. Run selectRefImages on the collected dataset

5. Run with ROS (edit launch file parameters if required)

roslaunch line_navigation_ros nav_online.launch

Build Instructions

1. Get Source codes from the repository

git clone <reopo url>
cd line_navigation_offline
git submodule update --init selectKeyImagesLines

2. Install required dependencies

sudo apt install libarpack2-dev libsuperlu-dev

3. Build executables required for mapping

cd selectKeyImagesLines  
./build_linematching.sh

4. Build Navigation code

For first time use setup.sh to compile the code. This will build custom ARPACK and SUPELU libaries

cd ..
./setup.sh 

After initial setup, the further compilation can be done by

./compile.sh

5. Steps to run naviagtion code after building

a) Get Reference images from teach sequence. (Refer here)

b) Test Script to run code run.sh
