Stereo calibration for beginners

Hello, I'd like to make a stereo program in C++ with OpenCV 2.4. I just tested cv::StereoBM and cv::StereoSGBM without calibration, but the result was inaccurate.

Could you give me good references (URLs) written about recent stereo calibration with OpenCV? I also want some sample codes.

Although I googled stereo calibration with OpenCV, there are many resources including old ones, someone's trials, I couldn't find a good reference. Please recommend a good introduction.

Thanks! -- Akihiko

can't help with a tutorial, but here's the sample code

This tutorial is quite recent and should guide you through all the necessary steps!

A camera calibration tool implemented on ROS (Robot Operating System) was easy to use.

camera_calibration/Tutorials/Stereo Calibration:
http://wiki.ros.org/camera_calibratio...

Although for me this tool would be enough, its source code is available online (written in Python though).

Other good pages were:

I just got 2 Xiaomi Yi 4k+ cameras which I plan to use for RGBD input for neural network training. And got into this calibration domain. I will probably need to test multiple methods and I am interested in <1mm precision for sure.

I have found following paper: https://webserver2.tecgraf.puc-rio.br...

There is also available Multi Cam Self Calibration package, which sounds promissing: https://github.com/strawlab/MultiCamS...

I am interested in your results.
