Question about calibrating a stereo camera #54

Open StarryPath opened 3 years ago

StarryPath commented 3 years ago

Dear @puzzlepaint , I want to calibrate a stereo camera. I tried to calibrate them together, but the program was difficult to converge. But when I calibrate them separately, they converge well. The most important thing is that I want to know the RT between two cameras. I can calculate R through the calibration results, but I don't know how to calculate T. Can you give me some ideas to solve the problem?Thanks!

In general, computing the relative pose between two cameras is not something that is related to the camera calibration project in this repository here, so I would consider it off-topic. As mentioned in #52, I cannot provide general Computer Vision support here, I am sorry.

Regarding the difficult convergence of the calibration with multiple cameras (but success with individual cameras), some ideas for possible reasons for that might be:
