Merhaba,
Video ile OCR uygulaması yapan bir kod kullandım ve bunu arayüzde 2 adet butona atayarak kullanmayı denemek istiyorum. Program webcam açılıyor ve klavyeden s ve q tuşlarına basarak ocr işlemini gerçekleştiriyorum. Bu s’e basma işlemini de butona atamak istiyorum.
from PyQt5 import QtCore, QtGui, QtWidgets
import algorithm
class Ui_MainWindow ( object ) :
def setupUi (self, MainWindow) :
MainWindow.setObjectName ( "MainWindow" )
MainWindow.resize ( 519, 354 )
self.centralwidget = QtWidgets.QWidget ( MainWindow )
self.centralwidget.setObjectName ( "centralwidget" )
self.pushButton = QtWidgets.QPushButton ( self.centralwidget )
self.pushButton.setGeometry ( QtCore.QRect ( 210, 140, 75, 23 ) )
self.pushButton.setObjectName ( "pushButton" )
self.pushButton_2 = QtWidgets.QPushButton ( self.centralwidget )
self.pushButton_2.setObjectName ( "pushButton_2" )
MainWindow.setCentralWidget ( self.centralwidget )
self.retranslateUi ( MainWindow )
QtCore.QMetaObject.connectSlotsByName ( MainWindow )
def retranslateUi (self, MainWindow) :
_translate = QtCore.QCoreApplication.translate
MainWindow.setWindowTitle ( _translate ( "MainWindow", "MainWindow" ) )
self.pushButton.setText ( _translate ( "MainWindow", "Open" ) )
self.pushButton_2.setText ( _translate ( "MainWindow", "Get" ) )
self.pushButton.clicked.connect ( self.OpenClick )
self.pushButton_2.clicked.connect ( self.OpenClick_2 )
def OpenClick (self) :
algorithm.FunctionAlgo ()
def OpenClick_2 (self) :
cf = 1
algorithm.tessfunc ()
if __name__ == "__main__" :
import sys
app = QtWidgets.QApplication ( sys.argv )
MainWindow = QtWidgets.QMainWindow ()
ui = Ui_MainWindow ()
ui.setupUi ( MainWindow )
MainWindow.show ()
sys.exit ( app.exec_ () )
buradaki main.py’den arayüzü çağırıyorum. Ocr işlemini:

print ( "Activated command mode!\nPress 's' to start text recognition" )
count = 0
while (True) :
ret, frame = cap.read ()
gray = cv2.cvtColor ( frame, cv2.COLOR_BGR2GRAY )
cv2.imshow ( 'Frame', gray )
ret, thresh = cv2.threshold ( gray, 0, 255, cv2.THRESH_BINARY_INV + cv2.THRESH_OTSU )
cv2.imwrite ( 'file.png', thresh )
if cf == 1 :
tessfunc ()
if cv2.waitKey ( 1 ) & 0xFF == ord ( 'q' ) :
cf = 0
if cv2.waitKey ( 1 ) & 0xFF == ord ( 's' ) :

if cv2.waitKey ( 1 ) & 0xFF == ord ( 'e' ) :
print ( "Terminating the program" )
break
cap.release ()
exit ()
ile yapıyorum. Burada en yukarıda tanımlanmış olan cf değeri tessfunc olarak tanımlı. Bunu da push buttonlara openclick1 ve openclick2 tuşları ile tanımladım. Ancak pushbutton_2 yi def olarak tessfunc() çağıramıyorum. Tuşa basılı değilse cf=0 ve s tuşu cf değerini 1 yapıyor ve ocr işlemi gerçekleşiyor.
Bunu yapabilmek mümkünse nasıl yapabilirim?
cf = 0 yani bunu global değişken haline getir diyorsun bu tamam fakat Bu durumda FunctionAlgoyu sınıfa dönüştürdüğümde kod çalışmıyor. Format sorunu çıkarıyor.
