  This paper presents DavarOCR, an open-source toolbox for OCR and document
understanding tasks. DavarOCR currently implements 19 advanced algorithms,
covering 9 different task forms. DavarOCR provides detailed usage instructions
and the trained models for each algorithm. Compared with the previous
opensource OCR toolbox, DavarOCR has relatively more complete support for the
sub-tasks of the cutting-edge technology of document understanding. In order to
promote the development and application of OCR technology in academia and
industry, we pay more attention to the use of modules that different
sub-domains of technology can share. DavarOCR is publicly released at
https://github.com/hikopensource/Davar-Lab-OCR.
