I’ve a doubt about the use of optional_opencv_calibration_file.
Is it working also with SVO? I mean, if I recorded an SVO file and then I want to use different calibration parameters at posteriori is it possible using optional_opencv_calibration_file? Or it will work only for a new record?
I’m calling get_camera_information() after used the above mentioned setup and it returns me different calibration parameters. Maybe is it about the autocalibration? Do the autocalibration runs and I need to specified in another field?
Not exactly, self-calibration, as explained in the documentation, is a refinement.
You must disable it if you want to use your exact calibration file without refinements.
Can I ask you why you want to use your calibration file?
The ZED factory calibration is an automated precise process and a manual calibration cannot reach the same results in precision.
A manual calibration is usually required if the camera is totally misaligned because it received a strong shock or if you are adding some kind of lens distortion in front of it (custom lenses, glass case, underwater applications, ecc).
If I disable the auto-calibration and then I get the calibration params, I will get the actual calibration parameters I specified in my custom calibration file or the ones at the time of the acquisition?
