Calibraation files not saving and camera intrinsics failing
-
Hi everyone,
Im using the Starling V2 board on a VOXL2 which is integrated on a custom drone. Currently I'm trying to set up VIO on the drone. I configured the camera extrinsics, calibrated the IMU. I went through the process of calibrating the gyro, accel, mag, baro, and level horizon on px4 through QGC. When I check for the files they are not saved:
voxl2 (M0054):~$ voxl-check-calibration
Calibration File Status:
Present /data/modalai/voxl-imu-server.cal
Present /data/px4/param/parameters_gyro.cal
Missing /data/px4/param/parameters_acc.cal
Missing /data/px4/param/parameters_level.cal
Missing /data/px4/param/parameters_baro_tc.cal
Missing /data/px4/param/parameters_mag.calDetected Missing Calibration Files
please run the required cals
https://docs.modalai.com/calibration/when I try to run qVIO server it failes because it is missing the opencv_tracking_front_intrinsics.yml. I've bee going throught the process of calibrating the tracking cameras with the 9x6 checker boards but its constantly failing. it says it most likely due to motion blur. the tracking cam im using is the AR0144 forward and down.
I've been running this line "sudo voxl-calibrate-camera tracking_front -s 9x6 0.023". I tried it also with fisheye but that didn't work as well.
Can someone provide a possible reasoning for this or share some tips to complete these steps?
@QSL -
@Idan-Fiksel Is the calibration card mounted to a hard backing piece so there are no warps or wrinkles in the checkerboard?
Did you print with a PDF so that the checkerboard measurements are accurate?
