如果我不是真正的Java专家，请有人帮我解决这个问题吗？谢谢高级。首先，我不知道opencv的新版本，也没有Java方面的经验。但是，请尝试将“\opencv\build\x86\vc12\bin”中的lib文件放入应用程序文件夹（编译的exe所在的位置）并重建应用程序。这是针对windows操作系统的，如果你在ubuntu上工作，一定要找到解决办法。
import org.opencv.imgcodecs.imgcodecs；
Imgcodecs.imencode（“.bmp”，frame，mem）；
您可以使用imgcodecs for opencv>3.0，而不是使用HighGUI。
imgcodecs.imencodeException in thread "Thread-2" java.lang.Error: Unresolved compilation problem:
Highgui cannot be resolved
