Openalpr: Indonesian License Plates

[simplyeazy]

Hello Matt

So I tried to train the OCR in train-ocr repository and the train.py didn't work. I've tried adjusting the tesseract dir path to my tesseract installation directory in ubuntu but still it says missing something like:
Two-Letter Country Code to Train: id
Processing: ./id/input/lid.indonesiaplatefont.exp0.box
Executing: /home/simplyeazy/Downloads/tesseract/tesseract -l eng ./id/input/lid.indonesiaplatefont.exp0.tif lid.indonesiaplatefont.exp0 nobatch box.train.stderr
sh: 1: /home/simplyeazy/Downloads/tesseract/tesseract: not found
mv: cannot stat ‘./lid.indonesiaplatefont.exp0.tr’: No such file or directory
mv: cannot stat ‘./lid.indonesiaplatefont.exp0.txt’: No such file or directory
sh: 1: /home/simplyeazy/Downloads/tesseract/training/unicharset_extractor: not found
Executing: /home/simplyeazy/Downloads/tesseract/training/mftraining -F ./tmp/font_properties -U unicharset -O ./tmp/lid.unicharset ./tmp/*.tr
I'm pretty new to Linux and tesseract and tried for like 2 weeks and still can't figure out what is wrong with my ocr training process.

Attached below is the TTF of Indonesia License Plate (the O and 0 are switched in the TTF so please use O when writing 0) please help me to get the traineddata. Thank you.

You'll need to get binaries (or compile) Tesseract for your system: https://github.com/tesseract-ocr/tesseract

The Tesseract training tools are used to train the ocr data

Hi Matt,
I have already put number 1 on each debug option within /etc/openalpr.conf. But, when i run command [alpr -c id /source/images.jpg --debug]. The recognition result on images only view temporary.
How to show recognition result on images ?

@andikaj Thank you for helping me out. Sorry, I forgot to close the issue. It's not an issue with openalpr but I and I've since solved the problem. For your question, please open a new issue for it.

Hello @andikaj , thank you for the training results file. By the way, how did you execute the training file (.box and .tif) to be generated as .traineddata file? I'd completely stuck by this error command. I want to train another .tif and .box file.

@reza4836 You can use your tif and box file with other tools to produce traineddata
