本文详细介绍了如何在C#中配置Halcon库，包括添加dll引用、设置窗口控件、实现摄像头捕获和人脸模板绘制，以及关键函数如打开相机、绘制模板和人脸识别。通过实例代码展示了如何在Windows Form应用中进行人脸匹配操作。

C#配置halcon

程序代码

C#配置halcon

将halcon中的两个文件放在程序的debug目录下

在程序员引用中，选择引用，引用halcondotnet.dll文件

在命名空间中写下using HalconDotNet

在项目选项中选择属性，取消掉首选32为生成

再再工具箱中右键，选择项，添加引入的 HalconDotNet，获得halcon窗口控件。关于配置，可以参考视频
