Enum BarCodeConfidence

Enum BarCodeConfidence

Namespace: Aspose.BarCode.BarCodeRecognition
Assembly: Aspose.BarCode.dll (25.1.0)

包含识别置信度级别

public enum BarCodeConfidence

字段

Moderate = 80

条形码（主要是1D条形码）的识别置信度，具有较弱的校验和或甚至没有校验和。可能包含一些编码文本中的误识别，或者如果 Aspose.BarCode.BarCodeRecognition.BarCodeResult.ReadingQuality 较低，甚至可能存在假识别。

None = 0

条形码的识别置信度，其中编码文本未被正确识别，或条形码被检测为可能的假条形码。

Strong = 100

通过 BCH 码（如 Reed–Solomon）确认的识别置信度。读取的编码文本中不得存在错误或假识别。

示例

此示例显示了 BarCodeConfidence 如何根据条形码类型而变化

//中等置信度
using (BarcodeGenerator generator = new BarcodeGenerator(EncodeTypes.Code128, "12345"))
{
    generator.Save(@"c:\test.png");
}
using (BarCodeReader reader = new BarCodeReader(@"c:\test.png", DecodeType.Code39, DecodeType.Code128))
{
    foreach (BarCodeResult result in reader.ReadBarCodes())
    {
        Console.WriteLine("条形码类型: " + result.CodeTypeName);
        Console.WriteLine("条形码编码文本: " + result.CodeText);
        Console.WriteLine("条形码置信度: " + result.Confidence);
        Console.WriteLine("条形码读取质量: " + result.ReadingQuality);
    }
}

//强置信度
using (BarcodeGenerator generator = new BarcodeGenerator(EncodeTypes.QR, "12345"))
{
    generator.Save(@"c:\test.png");
}
using (BarCodeReader reader = new BarCodeReader(@"c:\test.png", DecodeType.Code39, DecodeType.QR))
{
    foreach (BarCodeResult result in reader.ReadBarCodes())
    {
        Console.WriteLine("条形码类型: " + result.CodeTypeName);
        Console.WriteLine("条形码编码文本: " + result.CodeText);
        Console.WriteLine("条形码置信度: " + result.Confidence);
        Console.WriteLine("条形码读取质量: " + result.ReadingQuality);
    }
}
'中等置信度

    For Each result As BarCodeResult In reader.ReadBarCodes()
        Console.WriteLine("条形码类型: " + result.CodeTypeName)
        Console.WriteLine("条形码编码文本: " + result.CodeText)
        Console.WriteLine("条形码置信度: " + result.Confidence)
        Console.WriteLine("条形码读取质量: " + result.ReadingQuality)
    Next
End Using

    Next
End Using
