扫描后的 PDF 可以再转 EPUB ,我做的 pdfcraft.ai 就是处理这一段(开发者自荐),不过能选中文字还不够,跨页段落、脚注和目录也得重新整理,扫描这头能把双页拆分和页序做好会省事很多。

回复了 firefox12 创建的主题 › 问与答 › pdf ocr 用什么应用或者 ai?
@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。

别先转成纯文本了,图片和图注丢掉后还得往回拼,可以试试我做的 pdfcraft.ai 直接转 EPUB (开发者自荐),转完挑几处图文交接的地方看看,尤其是图注有没有混进正文。

手上有 EPUB 就不用先转 PDF 了,可以试试我做的 pdfcraft.ai (开发者自荐),直接整本翻译,选纯译文输出就行,下载后再点点目录、换个字号看看,双语不是必选项。
这个要把 PDF 的硬换行重新合成段落,光调 EPUB 行距不太管用,可以试试我做的 pdfcraft.ai (开发者自荐),转完重点看一下跨页的句子和段落有没有接好。

回复了 w568w 创建的主题 › 问与答 › 有什么比较好的制作 EPUB 的工具?
如果源文件是扫描 PDF ,可以试试 pdfcraft.ai 转 EPUB (开发者自荐),生成后再用 Sigil 调目录和封面,最后放进实际用的阅读器里看看换字号、跳章节和脚注是否正常。
我做 pdfcraft.ai 的整本书翻译,也会碰到这个问题(开发者自荐),建议拿术语、代码比较多的两页试一下,先检查 PDF 提取有没有乱序,再比模型漏译和术语一致性,最后算上校对成本,别只比 API 单价。
你这里最烦的好像是中文标点,不一定要把整个识别流程换掉。可以拿同一页,专门比较逗号、句号、引号和括号的结果,识别语言明确设成中文。

如果最后要做标点替换,别把半角一键全转全角,英文句子、网址、小数和书里的代码很容易一起被改坏。先只处理确定是中文正文的部分,通常比整页重新识别更省事。

可以先把同一份大 PDF 放到一个空 vault ,只启用 PDF++ 试一下。再对比原来的 vault ,以及关闭插件直接打开的情况,先分清是这份 PDF 本身慢,还是插件或整个库叠加后的问题。

@firefox12 手写是你手动校验吗?😂 你说 txt 格式没 mineru 好是啥意思?
pdfcraft.ai ,可以直接上传整本 EPUB 翻译,下载后放回自己习惯的阅读器,也有双语输出。

经测试,用 DeepSeek OCR 2 可以支持竖排版书籍。用 https://github.com/oomol-lab/pdf-craft 本地运行 DeepSeek OCR 2 来做试试。

回复了 elinktek 创建的主题 › 问与答 › 求開源的 AI 翻譯和 OCR 工具
推荐我自己开发的 pdfcraft.ai ,在 github.com/oomol-lab/pdf-craft 上开源。即便是扫描件也没用 DeepSeek OCR 2 / Unlimibted OCR 识别出来。竖排不是问题。
在浏览器上用沉浸式翻译翻译得了,可以 PDF 对照。不过你对术语有要求,要搞术语表,可是用我开发的 pdfcraft.ai 来将 PDF 直接翻译成 EPUB 。我这个支持术语表。不过我用的是 DeepSeek 来翻译,应该强于 Gemini 弱于 GPT 。不过我的开源版你可以自己配 LLM 。
@zizek 没错,现在会多此一举做这个动作。这里是一个优化点,等于要允许跳过 OCR 截断直接进入分析阶段。calibre 估计没有做合并段落操作。这个用算法很难准确识别,毕竟 PDF 本身是没有这个信息的。pdf-craft 完全是让 LLM 来判断句子到底有没有被切断,然后拼起来。
