TagStandard52h13 and TagCustom48h12 is not getting detected

Hello,

Are you able to detect it? I am getting an error saying reduce the max hemming distance.

Once you reduce the max hamming distance is still breaking. I have been looking into the code and seems like a problem at initialization. family->impl is not referenced when passing to apriltag_detector_add_family_bits in apriltag.c . I guess is something with the tagCustom48h12_create function. However, it runs normally if executed directly from a C project but not as a dll called from an external program.

Are you running this on Android? If yes then this tag family won't work directly on android due to memory issue. I have tweaked it little bit and it's working on android. I will soon publish it to github

Yes, the larger tag families can cause memory issues. You can try setting the max hamming distance to zero. Another option is to simply reduce the number of tags in that family (by editing the code, there's no more user-friendly way to reduce the number of tags yet)
