install / Calibration

Trying to implement Stereo Depth using OAK-FFC-6P, OAK-FFC IMX477 M12 * 2qt and C++

It's been 20 years since I haven't programmed, so it's very difficult.

1) I want to know what the installation order is when using C++
ex) c++ -> visual studio code -> opencv -> open3d -< DepthAi sdk -> depthai-core

2) I want to know if I can get the C++ Calibration source
I'd appreciate it if you could tell me what part I need to fix if I can get it.

Doc > API > Code Sample > Items related to Calibration are displayed.
I want to know what function each item has

Calibration Flash
Calibration Load
Calibration Reader

3) I want to know where the calibration results are stored
OAK-FFC-6P , external files, etc.

Isn't it necessary to include a calibration in the program?

4) I want to shoot vertically, but I want to know if I need to set it up separately

5) In case of re-calibration, please tell me what to do

Hi pshan

I think order doesn't really matter, as long as all libraries are installed.
I'm not sure what you mean by "calibration source"

Flash - Flashes calibration data of version 6 (gen2 calibration data) to the device - uploads your own calibration to FFC
Reader - Reads calibration data stored on FFC device
Load - loads and uses calibration data of version 6 (gen2 calibration data) in a pipeline - meaning you can use it in a script, without flashing it to the device

Calibration is flashed to the FFC6Ps internal memory.
If you performed horizontal calibration you don't need to re-calibrate unless you have moved the camera modules in any way (changed rotation/translation in respect to eachother). If the distance and rotation between the cameras is the same, you don't need to redo anything (just flip the whole thing vertically- it should still work).

Hope I answered your questions.

hi jakaskerl

Thank you for answer.

It's too late to check

It has been very helpful.

Calibration source means calibrate.cpp written in C++ like calibrate.py written in pyhthon.

Shooting vertically meant that the stereo camera was produced vertically from the production stage.

Hi pshan
To my knowledge there is no c++ version of our calibration script. You will have to recalibrate using python and that guide I sent above.

Thanks,
