Yeah, a brief googling indicates that this breaks things. How do we draw the wire frame field for simulation? That has lines out of the camera FOV
In some cases the distortion values you get from calibrateCamera result in a distortion function that is non-monotonic and the image (or projected points) can “wrap around”…So this could be what you are seeing. Maybe.

Describe the bug Strange distortion for apriltag bounding boxes that are very close
all good
Still fine
oop
To Reproduce Steps to reproduce the behavior:
Calibrate 3d on any camera
Get an apriltag very close to the camera
Screenshots / Videos see above
Platform:
Additional context I'm assuming this is because
Calib3d.projectPoints
does not handle the negative X real world points case well? Everything else is a floating point number so it shouldn't be that bad?
