Marker Dictionary #57

Open Asif6511 opened 5 years ago

Asif6511 commented 5 years ago

Hi,

Is it possible to use a different Aruco dictionary in this package? I know that now the package can detect markers from Original aruco dictionary. Please suggest a way to implement the detection on a different Aruco dictionary. Thanks.

Yes, You can easily use different dictionary just need to do some tweaks in the code it self. It will be easy if you would like to tell which dictionary ?

I would like to use the 7*7 dictionary. I find the marker detector function doesn't require dictionary parameter as supposed to the one in OpenCV arUco documentation. Also, since dictionaries are predefined, I don't find anywhere in the code where a particular dictionary is loaded. Please let me know if you found the snippet to do so. Thanks :)

Hi,

I have the same doubt, I would like to use the Dictionary: 4x4(50).

yah...the same question

Sinchiguano commented 5 years ago

same question but nor answer at all, anyone who solved the problem, let me know please.

I think the dictionary used is 5x5. This function is pretty much hard coding it. I haven't tried changing it but that might be a good place to start. :man_shrugging:
