ubii-processing-module-ocr
Tesseract OCR for Ubi Interact
Requirements
-
tesseract OCR Engine with appropriate language packs (>= 4.0.0)
-
opencv (some of the modules try to improve OCR performance with additional preprocessing, in the future this might become an optional requirement)
-
numpy
-
tesserocr
:warning: On windows tesserocr
can't be installed from PyPi. Windows builds for tesserocr are available for some python versions. Only python version >=3.7 < 3.8 is supported by both tesserocr
and the ubi-interact-python
node on Windows. Tesseract 5.+ should be compatible with Tesseract 4.0.0 (which is used for the Windows builds).
Known Issues
- The processing modules which use opencv seem to sometimes randomly crash under Windows
- Processing Frequency depends on the module implementation. Typically
TesseractOCR_EAST
allows for a slightly higher processing frequency and is run at 10fps while the TesseractOCR_PURE
module is run at 5fps.
