on chip calibration failed
How can I do?

Hi Gw Lee When the calibration error message Not enough depth pixels - low fill factor. Please retry in different lighting conditions occurs, it can indicate that the calibration needs to be performed with the camera placed in a location with stronger light illumination.
There are cases where the error will continue to occur no matter how much additional lighting is provided. In that case, using the 2.49.0 version of the RealSense Viewer can correct it. This is because there were changes to the on-chip tool in version 2.50.0 that can result in errors on some computers.
If problems do persist, instead of installing 2.49.0 I would instead recommend using the instructions at the link below to reset the camera in the Viewer to its factory new default calibration settings instead of performing an on-chip calibration.

Another option is to use an alternative official calibration tool called Dynamic Calibration.
If you are using Ubuntu then you can install the Dynamic Calibration tool using instructions pn page 14 onwards of the tool's user guide.

The only alternative to using the above methods would be to write your own calibration program script in C++ or Python language that accesses the On-Chip calibration function instead of doing it through the RealSense Viewer.
I again recommend trying the calibration factory reset method mentioned above to see if it meets your needs and avoids the needs to perform an on-chip or dynamic calibration.
