I’m using the M7 board for reading 1D barcodes, specifically the CODE39 type.
I have got the find_barcodes sample working but it only catches barcodes that are at 0 or 90 degree orientations. I’m assuming this is because the zbar algorithm only scans along the rows then columns of the image matrix.
How can I detect 1d barcodes that are at any orientation?
I’ve tried applying rotation_corr(z_rotation=45) but I get memory error on VGA and QVGA is too low for barcode reading.
