Issues running your example with GoPro9

[franillo]

Hi, I am trying to follow your calibration example with your data as explained here: https://github.com/urbste/OpenImuCameraCalibrator/blob/master/docs/gopro_calibration.md

If I extract your data and delete all the files except the mp4 files, I get following error:

================================================================== Optimizing IMU to Camera calibration using Spline Fusion.

WARNING: Logging before InitGoogleLogging() is written to STDERR F1123 11:35:26.019022 925709 continuous_time_imu_to_camera_calibration.cc:167] Check failed: ReadIMU2CamInit( FLAGS_gyro_to_cam_initial_calibration, imu2cam, time_offset_imu_to_cam) Could not read: /home/francisco/Downloads/GoPro9/dataset3/cam_imu/imu_to_cam_calibration_GH010164.json

So basically the file "imu_to_cam_calibration_GH010164.json" does not get written out, but I do not see any related error previously in the output text other than a few of these here: I1123 11:55:45.336704 926842 pose_estimator.cc:254] Removing view 2022 due to large z coordinate: -0.387445 vs median z coordinate -0.183183

If I extract the files provided and do not delete the calibration files, the program runs through with no problems. I hope somebody can help, this error might be related to some issues already mentioned here with the pyTheia lib?

Sorry for my late reply. I cannot reproduce these errors for the example dataset. Are you sure that you have all the latest versions of all libraries built? I added a Dockerfile and a description how to use it. Maybe check that all the versions are correct.

I also update the GoPro9.zip file and removed all temporary files. Maybe there were some temp files responsible for these errors.
