我为我的digitalPersona设备下载了一个注册示例代码供我们使用。它可能已经注册并验证指纹,但问题是它将指纹.fpt文件保存在文件夹中。我想将它保存在数据库中。
我无法序列化FMD对象类型的指纹,
private void OnCaptured(CaptureResult captureResult)
{
try
{
//check capture quality and throw an error if bad
if (!_sender.CheckCaptureResult(captureResult)) return;
SendMessage(Action.SendMessage, "la huella se capturo");
DataResult<Fmd> resultConversion = FeatureExtraction.CreateFmdFromFid(captureResult.Data, Constants.Formats.Fmd.ANSI);
if (captureResult.ResultCode != Constants.ResultCode.DP_SUCCESS)
{
_sender.Reset = true;
throw new Exception(captureResult.ResultCode.ToString());
}
if (count == 0)
{
indiceDr = resultConversion.Data;
XmlSerializer xml = new XmlSerializer(resultConversion.GetType());
StringBuilder sb = new StringBuilder();
StringWriter writer = new StringWriter(sb);
xml.Serialize(writer,resultConversion);
count += 1;
SendMessage(Action.SendMessage, "Ahora coloca tu pulgar en el lector");
SendMessage(Action.SendMessage, "gethashcode = "+sb.ToString());
}
else if (count == 1)
{
pulgarDr = resultConversion.Data;
count += 1;
SendMessage(Action.SendMessage, "Ahora coloca cualquier dedo en el lector");
}
else if (count == 2)
{
AnyFinger = resultConversion.Data;
Fmd[] fmds = new Fmd[2];
fmds[0] = indiceDr;
fmds[1] = pulgarDr;
//Verificar la documentacion del SDK
int thresholdScore = DPFJ_PROBABILITY_ONE * 1 / 10000;
IdentifyResult identifyResult = Comparison.Identify(AnyFinger,0,fmds, thresholdScore, 2);
if (identifyResult.ResultCode != Constants.ResultCode.DP_SUCCESS)
{
_sender.Reset = true;
throw new Exception(identifyResult.ResultCode.ToString());
}
SendMessage(Action.SendMessage,"Resultado de la identificación " + identifyResult.Indexes.Length.ToString());
SendMessage(Action.SendMessage, "coloca el indice" );
count = 0;
}
}
catch (Exception ex)
{
SendMessage(Action.SendMessage, "Error" + ex.Message);
}
}
答案 0 :(得分:2)
您可以将XML序列化为:
tempFingerPrint = Fmd.SerializeXml(resultConversion.Data);
答案 1 :(得分:0)
好吧,我建议您以byte []格式导入和导出Fmd数据。
Fmd>获取字节[]>将byte []转换为base64
然后
base64>解码为字节[]>然后导入到Fmd
我的意思是C#在Java中导出和导入。 导出(C#)
Fmd fmd = resultConversion.Data;
string base64Fmd = Convert.ToBase64String(fmd.Bytes)
导入(Java)
byte[] bFmd = Base64.getDecoder().decode(base64Fmd.getBytes("UTF-8"));
Fmd fmd = UareUGlobal.GetImporter().ImportFmd(bytes1, Fmd.Format.ANSI_378_2004, Fmd.Format.ANSI_378_2004)
我使用技术,因为在Java库SerializeXml
中找不到函数DeserializeXml
和dpuareu.jar
。
因此,这是我发现导入和导出Fmd的唯一方法。
但是,
这不会限制您使用Java还是C#,并且您可以将两者结合使用
