this software estimates the first distortion coefficient for an input image. theory behind this work can be found in this paper: https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=1234047
just install requirements
pip install -r requirements
check the configuration file for parameters and run
python3.7 test.py
pay attention to the starting coefficient value and the incremental one, they can be really different according to your camera. a bit of human tuning is probably required.
