Does 'Size of Marker' in pose Estimation include the black border?

I have a question about markerLength in functions like aruco.estimatePoseSingleMarkers

I had presumed that the markerLength includes the border bits and not a length that includes just the ‘data’ bits, but should include the black border in the physical measurement.

Someone verbally told me that it should be just the ‘data bits’, so I’m asking here
since the documentation is not clear, i.e.

“markerLength the length of the markers’ side. The returning translation vectors will be in the same unit. Normally, unit is meters”

Should the markerLength include the black border?

that “someone” doesn’t know what they’re talking about.

the size of a marker is the size of the black square. don’t overthink it. it is that simple.

see the green lines?
