Updating your housekeeping book is a tedious task: You need to manually find the shop name, the date and the total from every receipt. Then you need to write it down. At the end you want to calculate a sum of all bills. Nasty. So why not let a machine do it?
This is a fuzzy receipt parser written in Python. You give it any dirty old receipt lying around and it will try its best to find the correct data for you.
It started as a hackathon project. Read more about it on the trivago techblog. Also read the comments on HackerNews Oh hey! And there's also a talk online now if you're the visual kind of person.
To convert all images from the data/img/ folder to text using tesseract and parse the resulting text files, run
make run
A Dockerfile is available with all dependencies needed to run the program.
To build the image, run
make docker-build
To run it on the sample files, try
make docker-run
By default, running the image will execute the make run command. To use with your own images, run the following:
docker run -v <path_to_input_images>:/usr/src/app/data/img mre0/receipt-parser
The plan is to write the parsed receipt data into a CSV file. This is enough to create a graph with GnuPlot or any spreadsheet tool. If you want to get fancy, write an output for ElasticSearch and create a nice Kibana dashboard. I'm happy for any pull request.
