I need much more unique IDs of implemented of Aprilags.
My next option is Data Matrix, but the library libdmtx have low fps.
Have intentions to use another library, example: GitHub - zxing/zxing: ZXing ("Zebra Crossing") barcode scanning library for Java, Android
Or with libdmtx, an option is to pre-locate the code by image filtering.
A Data Matrix has a high contrast (in theory) and a given cell size. If you shring the image so that cells become one or two pixels large, the Data Matrix will stand-out as a highly textured area, and the gradient will strongly respond.
Have possible to work ?
