run

• step 1) camera calibraion pinhole-radtan for D435i

kalibr_calibrate_cameras --models pinhole-radtan pinhole-radtan --topics /camera/infra1/image_rect_raw /camera/infra2/image_rect_raw --bag [ROS bag file] --target aprilgrid_6x6.yaml

• step 2) verify result (0.1~0.2 px for a good calibration)

kalibr_camera_validator --chain chain.yaml --target aprilgrid_6x6.yaml

• step 3) camera-imu calibration

kalibr_calibrate_imu_camera --cam chain.yaml --target aprilgrid_6x6.yaml --imu imu0.yaml --bag [ROS bag file]

Trouble shooting

• no module named 'igraph'

# i) if you use vanilla Python
sudo pip uninstall igraph
sudo apt update
sudo apt install -y python2.7-igraph

# ii) if you use Anaconda
conda install -c conda-forge python-igraph

• no module named 'wx'
  • with conda

# takes long..
conda install -c conda-forge wxpython

• ImportError: dynamic module does not define module export function (PyInit_libnumpy_eigen)
  • without conda
  • may be caused from using Anaconda.
  • The environment variable named Python may be disrupted. Because Kalibr uses Python2.7, you should assign the path explicitly.

export PYTHONPATH=/usr/local/lib/python2.7/

• no module named 'rosbag'
  • without conda

pip install --extra-index-url https://rospypi.github.io/simple/ rospy rosbag

• ImportError: /home/zinuok/anaconda3/envs/kalibr/bin/../lib/libgio-2.0.so.0: undefined symbol: g_unix_get_passwd_entry
  • with conda

conda install --force -c anaconda glib==2.56.1

• ~ is protected within this context: from here

change line 466 protected into public in /usr/include/eigen3/Eigen/src/Core/MatrixBase.h 

• ImportError: No module named Cryptodome.Cipher

pip install pycryptodomex

• ImportError: libboost_python37.so.1.72.0: cannot open shared object file: No such file or directory
