Introduction

This repository aims to determine the value of analog gauge using some traditional algorithms via OpenCV-Python.

---

Getting started

You can use any analog gauge on the internet and run experiments with this source code, provided that the gauge must be captured directly without any distortion or oblique capturing angle. Running the following command line to clone and install some necessary library

git clone https://github.com/thanhhung0112/Hough-Transform-For-Meter-Reading.git
cd Hough-Transform-For-Meter-Reading
pip install -r requirements.txt

There are 2 ways to run this repo:

• Executing directly main file detect.py, you have to modify the target image which you want to read meter, just change directly inside detect.py.

python detect.py

• Executing api endpoint my_api.py. This will show the link of website to access, website interface is designed via HTML, you can absolutely modify it if you want. You have to modify camera.py to get an image following the way you want. In this source code, i connect to camera IP and get the frame of it when clicking to the button on the website. If you do not want to change it, please change params at line 18 to 22 inside my_api.py including min_angle (angle of min gauge value), max_angle (angle of max gauge value), min_value (min gauge value), max_value (max gauge value) and url (camera IP)

python my_api.py
