Hi All, I have started a project to do OCR on Identity Cards. I am learning to train tesseract models with custom fonts.
Please help me on this. Steps till now: 1. git pull https://github.com/tesseract-ocr/tesseract 2. Then I followed instructions on training package till command "sudo make training-install". 3.Downloaded eng.traineddata from https://github.com/tesseract-ocr/tessdata_best in tessdata folder 4. Command " src/training/tesstrain.sh --fonts_dir /usr/share/fonts --fontlist "Arial Bold" --lang eng --linedata_only --noextract_font_properties --langdata_dir ../langdata --tessdata_dir ./tessdata --output_dir ~/tesstutorial/engtrain" It is giving error: === Phase E: Generating lstmf files === Using TESSDATA_PREFIX=./tessdata [Tue Oct 16 05:41:31 UTC 2018] /usr/bin/tesseract /tmp/tmp.4EGdp9wW57/eng.Arial_Bold.exp0.tif /tmp/tmp.4EGdp9wW57/eng.Arial_Bold.exp0 --psm 6 lstm.train Tesseract Open Source OCR Engine v3.04.01 with Leptonica fseek(data_file_, static_cast<size_t>(offset_table_[tessdata_type]), SEEK_SET) == 0:Error:Assert failed:in file ../ccutil/tessdatamanager.h, line 173 ERROR: /tmp/tmp.4EGdp9wW57/eng.Arial_Bold.exp0.lstmf does not exist or is not readable Why the version is 4.0. Also, how do we download custom font for my Identity Cards.
