I'm having a hard time getting answers for openCV based questions on SO. I understand that programming related questions should be on SO. However, I am also doing camera calibration and have some questions related to that. Given that some of those questions are not specifically about openCV but how to perform the calibration, I wonder if DSP is a better place to ask those questions and if they would be on-topic here.
Provided you haven't asked the question on a different SE forum, feel free to ask it here. We have several OpenCV questions here.
Just try to ascertain whether it's really a programming question, rather than one related to image processing. Calibration questions (even using OpenCV) are on-topic; questions about which function to use... perhaps not so much.
