6/25/2023 0 Comments No ocr tool found in pyocrWorks like a charm, but wand/imagemagick currently might have some security issue (see ) Tool.get_available_languages() because that wasn’t english on my system. You should be to run the code from Step #5 after that. TESSERACT_CMD = os.environ ‘tesseract.exe’ if os.name = ‘nt’ else ‘tesseract’ I fixed it by changing the TESSERACT_CMD value to what is below Even after mapping the value to a PATH variable I couldn’t get it call tesseract correctly. I had to make one change tesseract.py in pyocr. Mine is C:\Program Files (x86)\Tesseract-OCR\ It should lead to the installation directory of Tesseract from step #1. You need to verify you have TESSDATA_PREFIX in your System Variables window in the Environment Variables window. Leave Environment Variables window open for now. Install git.Īnd then go to System-> Advanced system settings -> Environment Variables and add to the PATH variable the location of the git binary. I did this with the tesseract-ocr-setup-3.05.00dev.exe download. Here’s what I did if it helps anybody out there.Įasiest way to obtain tesseract for Windows is here: I ran across this on and wanted to try this on Windows as well. ![]() If you have any comments and suggestions then do let me know in the comments section below. I hope this tutorial was helpful for you guys! Now all of the recognized text has been appended in the final_text list. Now we just need to run OCR over the image blobs. Req_image.append(img_page.make_blob('jpeg')) We can loop over them and append them as a blob into the req_image list. Wand has converted all the separate pages in the PDF into separate image blobs. Note: Replace PDF_FILE_NAME with a valid PDF file name in the current path. Let’s do it! image_pdf = Image(filename="./PDF_FILE_NAME", resolution=300) Next step is to open the PDF file using wand and convert it to jpeg. Now we need to setup two lists which will be used to hold our images and final_text. We used the second language in the tool.get_available_languages() because the last time I checked, it was English. Now we need to get the handle of the OCR library (in our case, tesseract) and the language which will be used by pyocr. Note: I imported Image from PIL as PI because otherwise it would have conflicted with the Image module from wand.image. First of all, we will be importing the required libraries: from wand.image import Image You can take a look at the official docs on how to install it on your operating system. We will be using PIL as well because PyOCR needs it. We will be using it for converting PDF files to images: pip install wand ![]() It is the Python bindings for Imagemagick. We need to install two other dependencies as well before we can move on. We will be installing a latest one: pip install git Fortunately, there are some pretty nice bindings out there. Now we need to install the Python bindings for tesseract. It will install Tesseract along with the support for three languages. ![]() In Ubuntu you simply have to run the following command in the terminal: sudo apt-get install tesseract-ocr For the sake of simplicity I will be using Ubuntu as an example. It is very easy to install tesseract on various operating systems. I had to search a lot before I stumbled over the final solution. I am working on a project where I want to input PDF files, extract text from them and then add the text to the database. The issue arises when you want to do OCR over a PDF document. Hi there folks! You might have heard about OCR using Python. The most famous library out there is tesseract which is sponsored by Google. ![]() Source OCR on PDF files using Python February 24, 2016
