I want to get the orientation of a scanned document. I saw this post Pytesseract OCR multiple config options and I tried to use --psm 0 to get the orientation.
target = pytesseract.image_to_string(text, lang='eng', boxes=False, \ config='--psm 0 tessedit_char_whitelist=0123456789abcdefghijklmnopqrstuvwxyz') But I get an error:
FileNotFoundError: [Errno 2] No such file or directory: '/var/folders/jy/np7p4twj4bx_k396hyc_bnxw0000gn/T/tess_dzgtpadd_out.txt' I found another way to get the orientation using pytesseract:
print(pytesseract.image_to_osd(Image.open(file_name))) This is the output:
Page number: 0 Orientation in degrees: 270 Rotate: 90 Orientation confidence: 21.27 Script: Latin Script confidence: 4.14 
Instead of writing regex to get the output from a string , pass the parameter Output.DICT to get the result as a dict
from pytesseract import Output im = cv2.imread(str(imPath), cv2.IMREAD_COLOR) newdata=pytesseract.image_to_osd(im, output_type=Output.DICT) The sample output looks as follows: Use the dict keys to access the values
{ 'page_num': 0, 'orientation': 90, 'rotate': 270, 'orientation_conf': 1.2, 'script': 'Latin', 'script_conf': 1.11 } @lads has already mentioned the method whic can find orientation. I have just used re to get by how much degree do we need to rotate the image.
imPath='path_to_image' im = cv2.imread(str(imPath), cv2.IMREAD_COLOR) newdata=pytesseract.image_to_osd(im) re.search('(?<=Rotate: )\d+', newdata).group(0)
