Thanks for your response!
My dataset contains 64 boards with all kinds of views, including ones close to the edges, just not the very edges themselves (I am going for a stereo calibration, so if an image were to contain the very edges on one camera, the board could go offscreen on the other). If you think that poses a problem, I’ll try to capture a specific dataset for one camera where all the points are covered by corners, and report back what happens.
