@ZJJ2022415 Hi, you have a different opencv version from us. It seems that the FastLineDetector API has changed, so you can try to solve it in 3 ways.

1. Upgrade your opencv from 3.x to 4.x.
2. Change the related code in AirVO according to the API of opencv 3.x.
3. Use the docker recommended in the readme.

After I successfully compiled in dokcer, why didn't I generate"(find air_vo)/debug/traj.txt" under the defined path

@ZJJ2022415 Hi, you can set the log level to kERROR here and rebuild the project, which will show more detailed information about this error in the process. Thank you.
