OAK-D-Lite calibration

I have tried OAK-D-Lite calibration with both main and lite_calibration branches and found some problems.

Firstly, I ran calibrate.py in main branch with option -brd OAK-D-LITE then got the following message.

OAK-D-Lite Calibration is not supported on main yet. Please use `lite_calibration` branch to calibrate your OAK-D-Lite!!

Secondly, I switched branch to lite_calibration and ran calibrate.py again. The program progressed halfway, but I got an error “EEprom Write Failed!!”.

I compared the two branches and found that this error was caused by calibration_handler.setBoardInfo() because this property is protected. https://github.com/luxonis/depthai/blob/lite_calibration/calibrate.py#L531

Finally, I removed this function and added calibration_handler = self.device.readCalibration() with reference to the main branch so that it works correctly. https://github.com/luxonis/depthai/blob/main/calibrate.py#L551

My questions are as follows.

In the first place, why doesn’t the main branch support calibration with OAK-D-Lite?

Is it the correct way to use the likte_calibration branch to calibrate OAK-D-Lite? As mentioned above, the current implementation does not work correctly.

Please install the depthai version in that branch before using the calibration. Here are the steps.

1. git checkout lite_calibration
2. python3 install_requirements.py
3. python3 calibrate.py ...

Well, that does it xD it was easy to overlook.

Thank you!
