python - 如何使用 jTessBoxEditor 提高文本识别的准确性？

Question

我一直在尝试从扫描的 pdf 文档中提取数据。我已经将 pdf 文件转换为 jpeg 文件（我附上了下面的图片链接），用不同的字体裁剪了单词和数字，合并到一个 tiff 文件中，并使用 jTessBoxEditor 训练了字体以生成一种新的语言，我在Tesseract-OCR 从文件中提取数据。但我无法提取确切的数据。tesseract-ocr 的文本识别准确率很差。

有人可以提出一种提高准确性的方法吗？

Answer 1

我无法提取确切的数据

你用过image_to_string方法吗？

text = pytesseract.image_to_string(image)
