Hello, i read the guide for custom calibration, but as i see it can only be operated in windows 10? how can i get the intrinsic and extrinsic parameters for D435i under ubuntu 16.04 with python in OpenCV?

Hi @jasmin1026 If you are referring to the Dynamic Calibrator tool, page 14 onward of the user guide for the tool has instructions for installing it (the standard calibration tool and the custom calibrator API) on Linux.

If you are creating your own custom calibrator application, the API programming guide is here:

In regard to getting intrinsics and extrinsics with Python, the link below leads to a comment that has a script at the bottom of the comment that contains code for doing so.

@MartyG-RealSense Thanks for your answer.
I had read the programming guide for my own custom calibrator application, but in the guide only windows 10 is mentioned, i want to create the calibration for intrinsics (Especially for distortion）on Linux. so i don't know whether it also works on Linux?And Dynamic Calibrator works only for extrinsics, it's not so useful for me.

The Linux installation process for the tool installs both the Dynamic Calibrator and the Calibration API.

There are Linux details in the programming guide. It is much easier to find them if you do a Find search in the document for the word linux so that you can browse quickly through the 20 references to that word in the programming guide. That will lead you easily to Linux-specific information.

The extrinsics have the most effect on the camera image, so 99% of RealSense users do not need to calibrate intrinsics. There is an OEM version of the Dynamic Calibrator software (aimed at engineering departments and manufacturing facilities) that calibrates both intrinsics and extrinsics and is included in the $1500 USD professional OEM calibration target system in the RealSense Store.
