如何使用MICR检测和OCR自动检测和识别检查
附加的是使用Leadtools图像处理和OCR SDK的VS2017 C＃项目，以便自动执行检查过程。 正在做大部分工作的图像处理命令是MICRCodeDetectionCommand：https://www.leadtools.com/help/leadtools/v19m/dh/po/micrcodedetectioncommand.html
以下是实现此目的的相关方法：
private string DetectandRecognizeMICR(string fileName)
{
try
{
string micr = "";
//Initialize the codecs class and load the image
using (RasterCodecs codecs = new RasterCodecs())
{
using (RasterImage img = codecs.Load(fileName))
{
//prepare the MICR detector command and run it
MICRCodeDetectionCommand micrDetector = new MICRCodeDetectionCommand();
micrDetector.SearchingZone = new LeadRect(0, 0, img.Width, img.Height);
micrDetector.Run(img);
//See if there is a MICR detected - if not return
if (micrDetector.MICRZone == LeadRect.Empty)
return "No MICR detected in this file.";
//if there is a MICR zone detected startup OCR
using (IOcrEngine ocrEngine = OcrEngineManager.CreateEngine(OcrEngineType.Advantage, false))
{
ocrEngine.Startup(null, null, null, null);
//create the OCR Page
IOcrPage ocrPage = ocrEngine.CreatePage(img, OcrImageSharingMode.None);
//Create the OCR zone for the MICR and add to the Ocr Page and recognize
OcrZone micrZone = new OcrZone();
micrZone.Bounds = LogicalRectangle.FromRectangle(micrDetector.MICRZone);
micrZone.ZoneType = OcrZoneType.Micr;
ocrPage.Zones.Add(micrZone);
ocrPage.Recognize(null);
//return the MICR text
micr = ocrPage.GetText(-1);
}
}
}
return micr;
}
catch (Exception ex)
{
return ex.Message;
}
}请注意，如果您希望将其作为自动化过程，您不应该处理OCREngine，并且应该仅在启动应用程序/线程时启动它，然后在应用程序/线程停止后将其关闭/处理。
