Calibration bug

[ranjitkathiriya544]

Thanks for the reply,

1. In pattern calibration, if the pattern is too far from the camera, the calibration will not work effectively.
2. I have observed that for an image to be detected, more than 80% of the frame should be occupied by the pattern. If it’s less, detection fails.

I have added an example of a patten below, that might failed in scenario.

what I have observed, that if you crop a image, in below way then I can be able to detect. That's proofs 2 point.

Hi, @ranjitkathiriya544.

Are you able to move the calibration pattern closer to the camera or print a larger calibration pattern? Could you explain your use case? Maybe that would help us understand the need to have a calibration pattern that takes up a small portion of the camera's field of view.

I'm not terribly familiar with Ocean's square array pattern calibration process, but I imagine that calibration pattern taking up a large portion of the field of view of the camera is desirable. So the behavior you observed may be intentional and true to design rather than a bug.
