Neural network for recognition of meter readings
01/
Main information
Let's remember the classic methods of taking meter readings.
Once a month every Russian must pay for housing and communal service readings from their analog counter
FRISBI decided to facilitate this issue and considered several solutions.
Decision
«Equip apartments with automatic meters»
Expensive
(1,000,000 ₽/house)
Difficult to maintain
Not scalable
Decision
To teach a mobile application to read through the camera of housing and communal services counters

Interesting fact!

02
This is the first project of its kind in Russia
The neural network recognizes numbers in complex cases better than people

What difficulties did we face?
Semi-visible digits on analog counters
Problem
There was one more subtlety that we managed to cope with. The fact is that the counters are scrolled, and two numbers are visible in the window at the same time
With the help of labeled data, we trained the model for such instances - now it selects a number that is larger in value
Decision
Neural network speed on mobile phones
Problem:
Due to the insufficient capabilities of some mobile devices, the neural network required a simple solution
Our developers revised the code for a mobile device without losing the efficiency of the neural network.

Emotions from the project
Konstantin Kubrak
Manager, came to the project at the "Black Pearl"
Viacheslav Schultz
Developer, thought most of all
It's great that our system has learned to recognize the dials of counters of any type.
The whole team is delighted, because we are working with a completely new product and with a complex modern project, which has no analogues in the CIS

Our plans
Idea
Optimize the neural network for mobile operating systems:
Android
iOS
For what
So that the model can work faster on older phones and weaker phones
