halcon学习笔记(8)——QT显示halcon处理的图像和结果

前面讲过如何配置halcon和QT的联合编程,这次分享一下显示halcon处理后的图像,并输出处理后的结果。

第一步:如前面将的配置halcon的lib一样配置好环境;

第二步:将halcon中调试好的程序导出c++的代码。方法是HDevelop 》文件》导出,然后选择c++的输出,utf-8的格式,确定即可;

第三步:打开导出的c++文档,将内容main函数前面的内容全部复制到qt的要实现内容的.cpp文件里;

第四步:将action函数在QMain实现函数里加入编译即可显示halcon的图像在窗口了;

总结一下:上面四步是简单操作的,那么具体来讲如果你想让halcon的图像显示在你的窗口里,并且可以放置位置和想要的大小,那么就要仔细研究一下halcon导出的源代码了;我的办法是将halcon里的action代码修改复制到QMain实现函数里;action里有一句OpenWindow(0,0,hv_Width/7,hv_Height/7,0,"","",&hv_WindowID);其中0代表是就是窗口ID,写0代表当前系统窗口,如上面四步的结果,halcon处理后的图像并不显示在qt窗口里,而是单独显示在另一个窗口里;所以修改那个0,变为qt当前窗口的winID即可,我的具体代码如下:
