ambiguous documentation of markerSize data file field in ImportMarkerFeatures

[dsilas]

This seems really interesting and useful. However in the readme file about the markerSize field in the data file linked in ImportMarkerFeatures, the documentation seems a bit ambiguous. It says "markerSize: size of marker in pixels." Is that maximum apparent diameter in pixels? Major axis in pixels, as viewed in that photo? Some GCPs are circular, some are square, and So what is the value we should be using here? Thanks very much for the clarification

@dsilas The reason I kept that detail not very specific is because sadly I'm not exactly sure myself.
To make this addon work, I had to dig through the Meshroom source files to learn how their format works. I haven't had the time and energy to really dive into their algorithm implementations themselves, so I'm not certain how that size value is used exactly.
In the little research project that I made this addon for originally, I set the size value so that it's the average size of the diameter of the target in pixels. This seemed to work.

To be 100% clear, I'm not even sure if Meshroom actually uses the size for these markers, as they are effectively just points, but I kept the parameter exposed, just in case someone needs it.
