[Error reading EEPROM calibration] in ToF_depth API

Schotchaicharin

Hi,
I am using the OAK-FFC ToF 33D with OAK-FFC 4P to run the [tof_depth.py] example python code in the API. (ToF depth — DepthAI documentation | Luxonis)
The depth view is displayed, but there is error message in the command line as below:
[14442C10C169CBD600] [1.4] [6.556] [ToF(0)] [error] Error reading EEPROM calibration. temp_coefs_80
Does ths mean that the acquired depth is not calibrated?
And how do I fix this error?

Also, the displayed colorized depth is strange when Optical correction setting is ON as shown in the image below.

Does this problem related to the error mentioned above?
If not, How can I fix this problem?

Hi @Schotchaicharin
The module you have hasn't been calibrated. We will release some default calibration parameters EoW, but the precision will not be as good as factory calibration; so I suggest you write to support@luxonis.com so we can replace the module with the newly calibrated one.

Thanks and sorry for the inconvenience.

Thank you for your reply, I have a small question though,
Is "temp_coefs_80" refer to "Temperature coefficient" or "Temporal coefficient"?

Temperature coefficients for temperature correction.

Thanks,
