High Version QR Code

Issue: The higher the QR code version, the more data modules there are and the more challenging it is to read such dense QR codes.

Solution:

Dynamsoft Barcode Reader uses a special algorithm optimized for reading a dense QR code. Set the appropriate ScaleUpModes, which determines the process for scaling up an image for detecting barcodes with a small module size.

JSON Template:

{
    "ImageParameter" :  {
        "BarcodeFormatIds" : ["BF_QR_CODE"],
        "ScaleUpModes":["SUM_LINEAR_INTERPOLATION(0,4,6)"],
        "Name" : "Settings", 
        "ScaleDownThreshold" : 99999, 
        "Timeout":5000
    },
    "Version" : "3.0"
}
