自己根据SDK封装了动态库然后C#调用。
SDK 简介 本 SDK 适应于于 Windows 平台下的⾝份证识别系统,⽀持 C接⼜开发的 SDK,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 的⽅式另外随 SDK 附带⼀个鉴权激活⼯具LicenseTool.exe在license_tool ⽬录通过该激活⼯具可⽣成正常接 ⼊SDK 的激活 license ⽂件 license.zip(解压后可⽣成两个⽂件 license.ini 和license.key)达到通过鉴权 正常使⽤SDK 的⽬的。
激活工具授权 鉴权采⽤ SDK 附带的鉴权⼯具 LicenseTool.exe、双击打开 exe 后输⼊申请获取到的授权序列号执⾏按钮激活后会⽣成⼀个 license.zip ⽂件把这个⽂件解压后会⽣成 license.ini 和 license.key两个⽂件把这 2 个⽂件放置到 SDK 的 license ⽂件夹即可通过授权激活。另外⽀持鉴权⽂件路径定制化及模型⽂件路径定制化,可参考 SDK 示例鉴权⽂件 license.key 和 license.ini 的路径可参考SDK 代码示例也可以⽤ SDK 现成的默认路径。鉴权⼯具 LicenseTool.exe 如下所示在⼯具中输⼊申请得到的 license 系列号即可⽣成鉴权 zip ⽂件。解压 zip 后可⽣成 license.ini 和 license.key 两个⽂件。 SDK包结构 效果 问题
返回的坐标位置有问题猜测可能是内部缩放了图片导致后续等官方修复。
