script that uses easyocr for scanning .jpg files and renaming them based on read values

rename_jpgs

Overview:

There are 2 values that the script is extracting and using for renaming files:

• Order number in the format: 00012345
• Order name in the format: 412ABCDEF

Both of these values can be found (in ideal scenario) twice in the image. They are then concatenated and scanned file is renamed in this case to: '12345_412ABCDEF.jpg'

Installation:

To use this script, you need to have Python installed along with the following dependencies:

• os
• re
• easyocr

Usage:

• place the script in the directory containing your .jpg files
• run the script using Python
• the script will process all .jpg files in the directory and rename them based on the extracted text

Observations and bugs:

I am using this script at work almost every day. With most recent update there is only about 1% of incorrectly renamed files.

Bugs that I've noticed:

1. Most common bug was that the ocr failed to recognise either order number, or order name, or both. This lead to results like: '12345.jpg', '_412ABCDEF.jpg', '.jpg' This is in some cases due to physical damage of the documents itself (this is production environment - there can be stains and various damage occuring...). I am sure there is some optimisation that can be done to improve the success rate here, but for now this bug is the least concerning one.

   • Fixed. (Removed min_size parameter.)

2. Some files were renamed to '12345_403RB.jpg'. The '403RB' part here is a concern because it's wrong. This is some unrelated internal code that is not the order name. This bug is caused by not specific enough regex implemented in the code and needs to be fixed.

   • Fixed. (Updated regex.)

3. Traceback error. This occured only 3-5 times in over 2500 files but it is most concerning because it stops program from running. I cannot really recreate it (for now) therefore I do not really know what is causing it. I will try to implement some sort of try/except code to circumvent this error.

   • This is still occuring and I still cannot recreate the issue. I think it has something to do with file names before renaming... It happens rarely so the script is usable with almost zero issues, but it bugs me a lot.
