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](https://docs.luxonis.com/en/latest/pages/calibration/), 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

hi @"sagarlkhmn"#1037 sorry for issue, can you try the [modular_calibration](https://github.com/luxonis/depthai/tree/modular-calibration) branch?

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.

EEPROM error with OV9782 calibration

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