halcon联合C#的实时采集显示_c#联合halcon clone();

第一步：做好halcon图像采集算法并将其导出为C#代码。
打开VS2019选择Windows窗体应用程序并设置命名工程名称与保存路径。如下图：

可以看到一个类似于白板的窗体（适当拖动窗体大小），接着添加应用，如下如

单击引用在右击添加引用，引用的路径为halcon安装目录下的bin->dotnet35下的halcondotnet.dll(动态链接库)，若不知道在哪里，可回到桌面右击halcon图标查看文件所在位置，然后回到VS215单击浏览按钮做如下图操作：

做好添加引用，点击工具箱去添加显示halcon窗体的控件，如下图：

常规选项在工具箱的最后面，右击常规单击选择项，弹出如下图的窗口：

单击浏览选择上一步路径下的halcondotnet.dll(动态链接库)，确定后若出现如下图的内容说明添加成功，然后点击确认即可。

现在常规下面出现以下两个选项，如下图：

这里单击第二个且按住放到白板上，如下图：

这样关于联合halcon的界面内容就做完了，接下来就是布置界面，如下图：
