I recently tried running one of the ZED tutorials on a Jetson Nano using legacy ZED binocular camera hardware (I think it’s the ZED 2), and have encountered a persistent camera calibration error. This error persisted despite redownloading the standard calibration file as well as trying to manually calibrate the camera via the ZED Calibration program multiple times. Do you know of any workarounds for this issue?
