pdf ocr 用什么应用或者 ai？

试试 paddleocr 和 mineru

估计要花钱，手机端即便 google 的 app 也会出现因为角度问题将字识别错的问题。有个叫 text fairy 稍微好上那么一点点，会扫描后对齐，依然会出错。

只有国产的那些据说是云扫描的，确实试用的时候那些会出错的位置，它都不会出错，因为要钱，后来听书干脆下 pdf 文件。

@k74qr paddleocr 和 mineru 都试了 的确比其他的效果要好很多，虽然还不算完美 但是 缺字 漏字的情况少了 80%是有的

量不大的话推荐用多模态 AI 来识别，生成的格式会更好，还有一定的纠错能力。

试了一下使用 paddleocr 只能搞定 95%吧，有预算还是得上 AI

ai 怎么弄？

用 paddleocr 转了一下 90% 基本都是对的， 因为字本来也很清晰，但是排版还是游戏和原版的差别。算了 剩下的写了一个 py 校验了一下，手动改了 2 小时，第一版算是弄出来了。

我刚用 pdfcraft.ai 转了一下。

@moskize 我最后用了 mineru 加手写，paddleocr 效果好像更好些，但是 它的内容 转成 txt 格式好像没 mineru 好

@firefox12 手写是你手动校验吗？😂 你说 txt 格式没 mineru 好是啥意思？

@moskize 因为我最终的目的是 写了一个本地的 app ，用户可以直接使用 ipad 打开了 做练习，得分，所以最终还是需要

36. 35. (2023·上海杨浦·统考二模) My father ______ me a funny joke and I can't stop laughing every time I think of it.

A. told B. tells C. will tell D. is telling
这样 提示 A B C D 用户点击一个 判断对错。 提示结果。
ocr 出来其实还是有不少错的， 比如 35. 它会丢失， 那么我的答案就没办法 一一匹配，

所以 我让 ai 写个脚本 扫描 txt 按照一定的格式，1 2 3 4 如果 断开 乱了， 就提示 我再手动改改， 我可以让 ai 做，但是做出来 可能会把题目都变掉，所以 基本上还是用脚本跑比较准确。 大概 改了 70-80 个小错吧， 错误来自 缺少信息 和 少行。

txt 格式没 mineru 好，就是 它给了一个复杂的 json 我用脚本都没办法解析，它的格式不规则，很难直接处理，还是 mineru 直接给 txt 好。

@firefox12 你用 https://github.com/oomol-lab/pdf-craft 这个，就是我说的 pdfcraft.ai 的开源。

你用程序生成 EPUB 格式，他们本质就是 ZIP 封装的 XML 文件。pdf-craft 翻译 XML 文件的时候会保留 XML 结构本身。就是说 <div>My <span>father</span> told me...</div> 会被翻译成 <div>我的<span>父亲</span>给我说了...</div>。不要用 markdown ，会丢掉这些细节。

好的，下一次我再试试， 比较麻烦的就是 <div> <span> 这种很复杂的结构 我不知道如何用 python 统一处理，每道题的结构不一样 处理起来就很难
