I came across this problem after having read about this idea (which really works great): https://www.researchgate.net/figure/Example-of-e-ArUco-marker-based-on-a-7x7-sized-ArUco-marker-The-inner-marker-is-located_fig4_351864208

I was wondering, how it was possible, that the detection algorithm was not confused by the inner Aruco code. In fact it doesn't matter, if the field, which is covered by the inner Aruco code is white or black: It is always decoded as 29.

Would you have an explanation for this?

Thanks for your work, I found this repository to be very useful for generating ArUco markers 👍

I think it would be even more useful if we were able to specify multiple marker IDs to be shown in the same page. What I have in mind is something like this. How much effort do you think it would take to implement this feature?

For some applications, a padding might be necessary, as like a clean safety margin around the generated marker.

That would be easy enough to do on the browser's print dialog, if not for the header that states the ID of the generated marker.

Making that header optional would allow the print dialog itself to add custom margins and that could do the trick.

Having the option to manually set the padding would also be great, so the generated marker could have a fixed area around it with maybe an outline determining it, so it's easier to cut out after printing, without having to manually measure the padding.

I set marker size to 100mm, but when I use ruler to measure its length, it is not equal to 100mm？
I have set the web page or pdf file proportion to 100%.
Thank you very much.

Hi there,
I've seen this issue raised before, but i'm finding that the markers generated from your webpage are different than the arcuo 16h3 dict. Here's your marker 0 versus the aruco marker 0 (note, this is the compiled aruco, not that from open cv). Any thoughts? One helpful thing would be to provide perhaps the dictionary that aruco can take on the command line? You've referenced the .hpp, but i'm not sure how to make that readable from the command line... thanks!

aruco:

Hello,

I like the marker generator and use it sometimes if i (again) lost my markers. I need a lot the 1001 standard aruco, which is my test marker. In the past everything was fine, but due to an update aruco is limited to 0-999 because the options tag contains no data-number attribute. Can you add it? As far as i know aruco uses 10 bits (thus 0-1023) so 1024 as data-number would be correct

Thanks for your work and time in the generator

hi, thanks for your great online aruco marker generator ! and i have a question, when i generate 4x4 id= 0 marker , it show different from opencv same id marker, and i try other ,it is also differenct. so it is different dictionary ??? or how can i get the same marker with opencv
https://docs.opencv.org/3.2.0/d5/dae/tutorial_aruco_detection.html
Thanks a lot

Great project @okalachev definitly going to use this often!

Could you add a license to this project?

currently the implementation suggests only black and white as (respectively) front and back colors.
it would be nice to have it customized: say, blue for front color and gray for back color.
