我已将位图图像存储在服务器中，并希望通过 BiometricSDK 与我选择的另一个图像进行匹配。我不知道如何解决它。这是我当前的代码。

//Make finger print image get through SDK process
Boolean result = true;
var fprintsdk = new BiometricsSDK.FingerPrint.CFingerPrint();
var fprintresult = new BiometricsSDK.FingerPrint.CFingerPrint();

//get finger print image
fprintsdk.setFingerPrintImage(fprintsdk.getFingerPrintImage());

fprintresult.setFingerPrintImage(fprintresult.getFingerPrintImage());
FPrintImg.Image = fprintresult.getFingerPrintImageDetail();
FPrintImg.SizeMode = PictureBoxSizeMode.StretchImage;

//Open window to select finger print image
var open = new OpenFileDialog();
open.FileName = string.Empty;
open.Filter = "BMP|*.bmp"; //open text file as default
open.Multiselect = false;

if (open.ShowDialog() == DialogResult.OK)
{
    Bitmap bmp = (Bitmap) Image.FromFile(open.FileName); //select image and store out
    string Constr = "Provider=Microsoft.JET.OLEDB.4.0;Data Source = BankServer.mdb";
    OleDbConnection Conn = new OleDbConnection(Constr);
    Conn.Open();
    string sFingerPrint = "Select * from Server Where Hash = '" + ccinfo + "'"; //get data from server
    OleDbCommand cmd1 = new OleDbCommand(sFingerPrint, Conn);
    OleDbDataReader read1 = cmd1.ExecuteReader();
    while (read1.Read()) //loop all data
    {
        //(Problem Stuck over Here)
        if (read1["FingerPrint"].GetType() == bmp) //Comparison text file and database
        {
            Messagebox.show("Well Done");
        }
    }
}

我不知道您使用的是什么 SDK。因此，您需要搜索如何从这两个图像生成模板并匹配两个模板。生物特征匹配不是直接用图像而是用模板完成的。

如果您告诉我们您使用的是什么 SDK，也许我可以更好地回答。
