OCR of a truck's digital weight display via Raspberry Pi

I am looking for a talented Python developer to create an application that will run on a Raspberry Pi. This application will process the RTSP stream from an IP camera to find and read a digital weight display.

Key Features:
- The weight display is fixed in position, so the application will not need to track moving elements on the screen.
- The application should perform Optical Character Recognition (OCR) on the display and store the results in a text file.
- The whole system needs to function without any internet access.

Web Interface:
- A web page hosted on the Raspberry Pi will be used for testing and adjusting parameters. This includes tweaking OCR settings and viewing logs.
- The application should also allow me to start and stop the video stream from the web interface.

Ideal Skills and Experience:
- Strong proficiency in Python, particularly with video processing and OCR libraries.
- Experience in developing applications for Raspberry Pi.
- Understanding of setting up a local web server on Raspberry Pi.
- Familiarity with working without internet access.

The goal of this project is to create a reliable and efficient system to track and record weight data from a fixed digital display via video stream.
