Hello, I tried to reappear your algorithm, however some error occured when I run the preprocess program using your bags.
the command and the result are as fellows:
rosrun direct_visual_lidar_calibration preprocess ../direct_data/livox_ros1/ ../preprocessed/ -av
data_path: ../direct_data/livox_ros1/
dst_path : ../preprocessed/

I don't know how to solve it, so please help me to solve this issue, besides, I wonder confirm the version of Dependencies such as openCV.
thank you!

I think this is because you use a different version of opencv. The verified version of openCV is 4.2.0, please check if you get the build warning when you run catkin_make for the rospackage. similar to this:

warning: libopencv_core.so.408, needed by /your/path/to/the/catkin_ws/devel/lib/libdirect_visual_lidar_calibration.so, may conflict with libopencv_core.so.4.2

In this warning it says that the openCV 4.8.0 has some incompatible files to the openCV 4.2.0.
