Hello
I am trying to extract text from a picture, but I always geht an empty text.
The used picture in the code for image_to_string('temp2.jpg') is added
below.
I tried to treshold with opencv, but there was just a slice difference to
the picture added below.
Is there a step missing? is the picture format jpg wrong? is it impossible
because of white and balck fields appearing as text on the picture ..?
I am urgently searching for help and hoping for an answer in short time.
#!/usr/bin/env python
import os
import subprocess
from picamera.array import PiRGBArray
from time import *
from picamera import PiCamera
from datetime import datetime, timedelta
import cv2
try:
import Image
except ImportError:
from PIL import Image, ImageEnhance, ImageFilter
from pytesseract import *
#EXTRACT TEXT
print 'pytesser:'
#img = Image.open('/home/pi/camera/IMAGE-2017-05-04_141433.png')
img = Image.open('artikelbild-02.jpg')
im = img.convert('RGBA')
enhancer = ImageEnhance.Contrast(im)
im = enhancer.enhance(3)
im = im.convert('1')
im.save('temp2.jpg')
#use tesseract library to extract text from
text = pytesseract.image_to_string(Image.open('temp2.jpg'))
print "Text:"+text
#what the text contains
if "DHL" in text:
print 'DHL Lieferant'
elif "Post" in text:
print 'Postbote'
elif "GLS" in text:
....
