halcon|halcon联合C#的实时采集显示

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。

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:
