Great. Could you clarify:
By ‘more photos you add’, does that mean each marker appearing in a larger number of photos? i.e. more overlap.
By ‘clearer will the component be’, what does that mean? either a valid component is formed, or not - it’s binary.
This is valuable, because placing markers may be the best way to align photos of building interiors with featureless wall areas. Some idea of optimum (or sufficient) density of placed markers, and photos overlap, would help, alongside experimentation. This abstracted question, ‘empty scene with nothing but coded targets’, should help to clarify.
