What's Changed

• 2025/05/24 1.3.12 Released

  • Added support for ppocrv5 model, updated ch_server model to PP-OCRv5_rec_server and ch_lite model to PP-OCRv5_rec_mobile (model update required)
    • In testing, we found that ppocrv5(server) shows some improvement for handwritten documents, but slightly lower accuracy than v4_server_doc for other document types. Therefore, the default ch model remains unchanged as PP-OCRv4_server_rec_doc.
    • Since ppocrv5 enhances recognition capabilities for handwritten text and special characters, you can manually select ppocrv5 models for Japanese, traditional Chinese mixed scenarios and handwritten document scenarios
    • You can select the appropriate model through the lang parameter lang='ch_server' (python api) or --lang ch_server (command line):
      • ch: PP-OCRv4_rec_server_doc (default) (Chinese, English, Japanese, Traditional Chinese mixed/15k dictionary)
      • ch_server: PP-OCRv5_rec_server (Chinese, English, Japanese, Traditional Chinese mixed + handwriting/18k dictionary)
      • ch_lite: PP-OCRv5_rec_mobile (Chinese, English, Japanese, Traditional Chinese mixed + handwriting/18k dictionary)
      • ch_server_v4: PP-OCRv4_rec_server (Chinese, English mixed/6k dictionary)
      • ch_lite_v4: PP-OCRv4_rec_mobile (Chinese, English mixed/6k dictionary)
  • Added support for handwritten documents by optimizing layout recognition of handwritten text areas
    • This feature is supported by default, no additional configuration needed
    • You can refer to the instructions above to manually select ppocrv5 model for better handwritten document parsing

• 2025/05/24 1.3.12 发布

  • 增加ppocrv5模型的支持，将ch_server模型更新为PP-OCRv5_rec_server，ch_lite模型更新为PP-OCRv5_rec_mobile（需更新模型）
    • 在测试中，发现ppocrv5(server)对手写文档效果有一定提升，但在其余类别文档的精度略差于v4_server_doc，因此默认的ch模型保持不变，仍为PP-OCRv4_server_rec_doc。
    • 由于ppocrv5强化了手写场景和特殊字符的识别能力，因此您可以在日繁混合场景以及手写文档场景下手动选择使用ppocrv5模型
    • 您可通过lang参数lang='ch_server'(python api)或--lang ch_server(命令行)自行选择相应的模型：
      • ch ：PP-OCRv4_rec_server_doc（默认）（中英日繁混合/1.5w字典）
      • ch_server ：PP-OCRv5_rec_server（中英日繁混合+手写场景/1.8w字典）
      • ch_lite ：PP-OCRv5_rec_mobile（中英日繁混合+手写场景/1.8w字典）
      • ch_server_v4 ：PP-OCRv4_rec_server（中英混合/6k字典）
      • ch_lite_v4 ：PP-OCRv4_rec_mobile（中英混合/6k字典）
  • 增加手写文档的支持，通过优化layout对手写文本区域的识别，现已支持手写文档的解析
    • 默认支持此功能，无需额外配置
    • 可以参考上述说明，手动选择ppocrv5模型以获得更好的手写文档解析效果
