Where is CustomCalibration tool and Chessboard Pattern?

[ravijo]

Hi,

Based on Intel RealSense D400 Series Custom Calibration Whitepaper, I should be able to find CustomCalibration tool. But I can't.

I am sorry but can you please provide:

• CustomCalibration
• Chessboard Pattern

Hi @ravijo You have already located the official chessboard calibration target pattern, as mentioned in your other case at #10074

In regard to the Calibration API for developing a custom calibration tool, you can visit the link below to find the PDF document of the Programmer's guide for Intel RealSense D400 Series calibration tools and API. The current edition at the time of writing this is dated July 2021.

My understanding is that the Calibration API is obtained by installing the Calibration Tool, as described on page 11 of the above PDF Programmer's Guide.

You do not need to necessarily develop your own custom calibration application though, as the standard Dynamic Calibration pre-made tool should be sufficient for 99% of RealSense users.

There is also the alternative option of calibrating the camera using the On-Chip calibration tool, which is accessible under the 'More' option of the RealSense Viewer's options side-panel or with program scripting. On-Chip calibration has the advantage of being built into the camera firmware driver and so does not require installation of a separate software tool like the Dynamic Calibration tool does.

Hello @MartyG-RealSense

I understand.

Just to confirm, do you mean that the CustomCalibration tool is not required because of the following two tools

• Dynamic Calibration tool (for extrinsic calibration)
• On-Chip Calibration (for intrinsic calibration)

Please see page number 22 of Intel-RealSense-D400-Series-Custom-Calibration-Whitepaper.pdf. If I understood you correctly, the picture/process shown on page number 22 is not required.

Please confirm.

You are correct, you do not need to create your own custom calibration application and the pre-made Dynamic Calibration or On-Chip tools should be fine. In the 4 year history (so far) of the 400 Series cameras, there have only been a few enquiries that I know of regarding custom-developing a calibration tool with the Calibration API.

Thanks a lot.
