Beschreibung

read_ocr_class_mlpread_ocr_class_mlpReadOcrClassMlpReadOcrClassMlpReadOcrClassMlpread_ocr_class_mlp liest einen mit write_ocr_class_mlpwrite_ocr_class_mlpWriteOcrClassMlpWriteOcrClassMlpWriteOcrClassMlpwrite_ocr_class_mlp abgespeicherten OCR-Klassifikator ein. Da das Trainieren eines OCR-Klassifikators relativ lange dauern kann, wird der Klassifikator typischerweise in einem Offline-Prozess trainiert und mit write_ocr_class_mlpwrite_ocr_class_mlpWriteOcrClassMlpWriteOcrClassMlpWriteOcrClassMlpwrite_ocr_class_mlp gespeichert. Im Online-Prozess wird der Klassifikator mit read_ocr_class_mlpread_ocr_class_mlpReadOcrClassMlpReadOcrClassMlpReadOcrClassMlpread_ocr_class_mlp gelesen und danach zur Klassifikation mit do_ocr_single_class_mlpdo_ocr_single_class_mlpDoOcrSingleClassMlpDoOcrSingleClassMlpDoOcrSingleClassMlpdo_ocr_single_class_mlp oder do_ocr_multi_class_mlpdo_ocr_multi_class_mlpDoOcrMultiClassMlpDoOcrMultiClassMlpDoOcrMultiClassMlpdo_ocr_multi_class_mlp verwendet.

HALCON stellt eine Anzahl vortrainierter OCR-Klassifikatoren zur Verfügung (siehe „Solution Guide I“, Kapitel 'OCR', Abschnitt 'Pretrained OCR Fonts'). Diese vortrainierten OCR-Klassifikatoren ermöglichen es, eine Vielzahl an Zeichensätzen zu lesen, ohne vorher einen OCR-Klassifikator trainieren zu müssen. Das Training der vortrainierten OCR-Klassifikatoren erfolgte mit Zeichen, die dunkel auf hellem Hintergrund gedruckt waren.

Ausführungsinformationen

Dieser Operator liefert ein Handle zurück. Es ist zu beachten, dass der Zustand einer Instanz dieses Handletyps durch bestimmte Operatoren geändert werden kann, obwohl das Handle als Eingabeparameter in diesen Operatoren verwendet wird.

Parameter
