由于项目需要，需要在QT中进行图片分类，准备用opencv自带的dnn模块，调用训练好的模型。
win7/64+QT5.11.1+opencv3.4.1

1.QTCreator配置opencv

先测试是否可用，QTCreator的pro文件先添加opencv库。（默认系统环境变量已添加opencv的bin目录）

CONFIG(debug,debug|release) {
   
   
    TARGET = $$join(TARGET,,,_d)
}


Debug {
   
   
        contains(QMAKE_COMPILER_DEFINES, _WIN64) {
   
   
                LIBS += -LH:/opencv/opencv/newbuild/install/x64/vc15/lib				-lopencv_img_hash341d
                LIBS += -LH:/opencv/opencv/newbuild/install/x64/vc15/lib				-lopencv_world341d
                DESTDIR = ./Bin/x64
        }
        else {
   
   
        }
}
else {
   
   
        contains(QMAKE_COMPILER_DEFINES, _WIN64) {
   
   
                LIBS += -LH:/opencv/opencv/newbuild/install/x64/vc15/lib				-lopencv_img_hash341
                LIBS += -LH:/opencv/opencv/newbuild/install/x64/vc15/lib				-lopencv_world341
                DESTDIR = ./Bin/x64
        }
        else {
   
   
        }
}

INCLUDEPATH += \
            H:/opencv/opencv/newbuild/install/include\
            H:/opencv/opencv/newbuild/install/include/opencv\
            H
