背景 为使客户、第三方开发者等能够更快速、方便的接入使用百度办公文档识别 SDK、促进百度 OCR产品赋能更多客户特设计支持 c语言的 Windows 高精通用文字识别 SDK该 SDK 提供 pdf 转图文的能力和通过 pdf 识别文字并可以转存成 word 的能力。
SDK 简介 本 SDK 适应于 Windows 平台下的人脸识别系统, ,开发者可在 vs2015 下⾯进⾏开发推荐使⽤不保证其他版本 vs 都兼容。SDK 采⽤ c的动态库 dll 的⽅式。上层 UI 框架支持主流框架如QT,MFC 等。
自动批量授权 鉴权采用自动激活的方式进行授权可参考 SDK 示例中把申请到的授权 key 串码(仅支持批量授权)填入到 license 文件夹的 license.key 文件中运行 SDK即可自动激活生成授权文件 license.ini 在license 文件夹中。SDK 授权是通过接口方法 auth_from_file 实现该方法参数分别是传入授权 key 的串码和授权文件 license.ini 的绝对路径。确保参数正确后在 SDK 中运行了该方法就会生成授权license.ini 文件。若授权正确该方法的返回值为 0若非 0则为授权失败错误原因可根据错误码参考后续文档查看。
离线授权 离线授权采用从 sdk 附带的 license_tool 工具bin 文件夹的 license_tool 下双击 LicenseTool.exe再点击拷贝把设备指纹拷贝到剪贴板中到百度 OCR 官网进行离线激活填入得到的设备指纹后从官网下载离线授权文件解压形成 license.key 和 license.ini 两个文件替换到 SDK 中的 license 文件夹中运行 SDK若在 SDK 的授权方法 auth_from_file 中返回 0则为通过了授权。具体可参考SDK 中的授权代码示例 项目 代码
