meter-reader

meter (water, gas, electricity) reader from image to digits

Goals :

• Read meter (water, gas, electricity)
• Hardware independant (works with any camera that can produce a fixed image)
• Keep simple

Process :

• Get image from any camera (local or http)
• Setup a python compatible apps to process the image (docker, flask or other python compatible apps)
• [onetime] set regions to process
• Produce digits from image

Solutions 1 - python only : (tested on Python 3.12.3)

pip install -r requirements.txt

python draw_regions.py

input image source and draw digits regions from left to right

python meter_reading.py

optional arguments : --image_source http://192.168.1.113/img_tmp/alg.jpg --model model.tflite --regions regions.txt --no-gui --no-output-image

Solutions 2 - webapp - flask_meter_reader :

pip install -r requirements.txt

python app.py

*- http://127.0.0.1:5000

• [onetime]Go to Draw Regions> input you image (http or local) and set regions

• Return to index and process you image

Todos:

• test and improve
• make a hassio component (not actually possible cause nor tflite-runtime nor tensorflow supports python 3.13)
