I have a bunch of photos of energy meters. In every photo there is info written on the meter and also a seven segment display which has reading in kWh. Also, there is logo of meter manufacturer. I want to extract information like meter serial number, meter manufacturer, meter reading in kWh(7 segmented display).

I have used easyocr module to detect text and using that I have achieved to extract meter serial numbers but for kWh reading easyocr fails to detect the digital digits.

Currently I have 2 requirements, one is to detect digits from 7 segment display and also detect manufacturer from logo symbol in meter. Only 2-3 different manufacturers are there so I need to train based on only 2-3 logos. But I don’t know how to do it.

Any help or guidance with steps kr procedure will be really appreciated.

I tried googling, searched on YouTube but not getting any roadmap for the same. I have tried other ocr modules like tesseract but it also fails.
