| Abstract | 本文提出一種多模型融合的OCR後處理方法，採用獨特的版面分析和對齊算法，整合了整頁檢測模型、字識別模型、列識別模型與語言預訓練模型等深度學習模型，實現了超越單一模型的效果。全文錯誤率達到1.64%，僅為單一模型平均錯誤率的23%。在各類常規古籍版式場景中，該方法具有較好的泛用性。
This paper proposes a post-OCR method of multi-model ensemble, which uses a unique layout analysis and alignment algorithms, and integrate different types of deep learning models, such as the full-page character detection model, character recognition model, line recognition model and language pre-training model, and achieves effects beyond a single model. The full-text error rate reaches 1.64%, which is only 23% of the average error rate of a single model. In various conventional ancient book layout scenarios, this method has good generalization. |
