Read and recognize the counter of an electricity meter with OpenCV.
Forked from @skaringa with MySQL-DB feature.
- g++, make
- OpenCV 2 (Debian/Ubuntu/Raspbian:
apt-get install libopencv-dev) - MySQL-Client (
apt-get install mysql-client libmysqlclient-dev) - log4cpp (
apt-get install liblog4cpp5-dev)
cd emeocv
make
emeocv [-i <dir>|-c <cam>] [-l|-t|-a|-w|-o <dir>] [-d <schedule>]
[-f <image>] [-s <delay>] [-v <level>] [-p]
Image input:
-i <image directory> : read image files (png) from directory.
-c <camera number> : read images from camera.
Operation:
-a : adjust camera.
-o <directory> : capture images into directory.
-l : learn OCR.
-t : test OCR.
-w : write OCR data to MySQL database. This is the normal working mode.
Options:
-d <t> : ONLY WORKS WITH OPERATION "-w"! If time is divisible without
remainder by t, write to DB. e.g.: 1h = every full hour or
10m = every full 10 minutes. (t=<number>[h|m|s]) (default=None).
-f <image> : ONLY WORKS WITH OPERATION "-w"! Output capture image to static
path, when OCR data is written to DB. (e.g.: image=<dir>/<file.png>).
-s <n> : Sleep n milliseconds after processing of each image (default=1000).
-v <l> : Log level. One of DEBUG, INFO, ERROR (default).
-p : Print log also in Console (default=False)
There is a tutorial that explains use case and function of the program: OpenCV practice: OCR for the electricity meter or OpenCV Praxis: OCR für den Stromzähler (in german language).
