我一直在编程FaceRecognizer库的Java版本。我可以在Java OpenCV项目中成功初始化一个新的FaceRecognizer(默认情况下为Fisherface)。我使用JNA来完成此任务。但是最近，我发现“train”方法存在错误，因此我决定在DLL文件中进行整个识别，最后返回一个 double 值。但是当我像这样制作一个新的FaceRecognizer时:
Ptr<FaceRecognizer> model = Algorithm::create<FaceRecognizer>("FaceRecognizer.Fisherfaces");
要么
Ptr<FaceRecognizer> model = createFisherFaceRecognizer();
它确实可以编译并成功构建!但是当我用它们像这样训练时:
model->train(libList,idList);
(libList是 vector ，idList是 vector )
JVM(通过JNA到我的Java OpenCV项目)。
它说 :
A fatal error has been detected by the Java Runtime Environment:
EXCEPTION_ACCESS_VIOLATION (0xc0000005) at pc=0x60b2510b, pid=31264, tid=13256
Problematic frame:
C [opencv_core248.dll+0x510b]
我猜想这与引用或指针有关，因为即使我运行
model->name();
它也会崩溃。似乎是“模型”存在问题。
非常感谢您的帮助!非常感谢你!

最佳答案
我搞定了!是的，“createFisherFaceRecognizer()”存在问题，因为它源自“cv.hpp”。它显示在Visual Studio的IntelliSnse中，因为它来自类Cv，但是我没有导入正确的库。我在每个opencv.lib文件的末尾添加了“d”，并且还导入了cvcore和cvcorex。现在可以了。如果您遇到像我这样的问题，可能就是这样。完成后，我将很高兴分享我的代码。
