Instructions

C++

To run the code in C++, please go into the cpp folder, then compile the disparity_params_gui.cpp, obstacle_avoidance.cpp and disparity2depth_calib.cpp code files, use the following:

mkdir build
cd build
cmake ..
cmake --build . --config Release

Use the following commands to execute the compiled files:

./build/disparity_params_gui
./build/disparity2depth_calib
./build/obstacle_avoidance

Python

To run the code in Python, please go into the python folder and refer to the following to use the disparity_params_gui.py, obstacle_avoidance.py and disparity2depth_calib.py files respectively:

python3 disparity_params_gui.py
python3 disparity2depth_calib.py
python3 obstacle_avoidance.py
