Hello,

I have an Oak-D pro wide camera with OV9782 color sensor. The depth cloud i get from camera is not very accurate and hence i am trying to calibrate the camera intrinsics. I am using the calibration script provided under depthai git package. I switched to ov9782_calib branch for calibrating the camera. Following the steps mentioned here, i get to the end of the process and i get the below error before flashing the calibrated json to the camera?

"No PROTECTED permissions to override protected EEPROM fields."

Is there something I am missing? Are there any other steps to perform intrinsic calibrations?

Best,
Sagar Lakhmani

Thanks for the reply. I will try the modular calibration going forward. However, I was able to fix the issue by doing the below steps.

  • Checked out main branch on depthai repo.
  • Ran the install_requirements.py script to install system dependencies.
  • Switch the branch to ov9782_calib.
  • Ran calibration script which gave no issues.

I suspect there's a mismatch between the requirements on main vs requirements on ov9782_calib branch. After switching the branch, not running install_requirements.py seemed to solve the problem.
