Give me steps to perform On- Chip Calibration on D415

[bhusan2002]

I have read the white paper many time but not able to do the on chip calibration i am getting the error "Not enough depth pixels Please retry with different lighting conditions some how I am not able to do the on chip calibration and also how can i know the health value for the camera.

Ways I have tried:

• Kept it flat wall got the same error.
• Kept it towards a flat sheet same error.

Can you share detailed step to do this.

Hi @bhusan2002 On some computers the On-Chip calibration tool will only work correctly and not show the 'Not enough depth pixels' error if the 2.49.0 version of the librealsense SDK is used, as there were changes to how On-Chip worked from version 2.50.0 onwards that cause On-Chip to not work on some computers.

An alternative to calibrating the camera is to reset it to its factory-new default calibration using instructions at #10182 (comment)

There is also another RealSense calibration tool called Dynamic Calibration that you could try. It can be downloaded and installed for Windows at the link below.

Or if you have Ubuntu, instructions for an Ubuntu installation of the tool can be found at page 14 onwards of the user guide.
