基于Qt的opencv使用
1.pro
QT += core
QT -= gui
INCLUDEPATH += E:\opencv_3.2\build\install\include
#E:\opencv_3.2\build\install\include\opencv\ 这是较全的路径,因为在main中加入了opencv,故这里写到opencv即可
#E:\opencv_3.2\build\install\include\opencv2\
#E:\opencv_3.2\build\install\include
# E:\opencv_3.2\opencv-3.2.0\include\opencv\ 开始的错的一种
# E:\opencv_3.2\opencv-3.2.0\include\opencv2\
# E:\opencv_3.2\opencv-3.2.0\include
LIBS += -LE:\opencv_3.2\build\install\x86\mingw\bin -lopencv_core320 -lopencv_highgui320 -lopencv_imgcodecs320
#LIBS += E:\opencv_3.2\build\lib\libopencv_* 两种路径方式都可以,推荐上面一种
#LIBS += E:\opencv_3.2\build\lib 不能写成这种
#HEADERS 指定项目中的所有头文件 .h文件 此文件中没有
CONFIG += c++11
TARGET = 1 #指定目标文件的名称,自动生成
CONFIG += console
CONFIG -= app_bundle
TEMPLATE = app
SOURCES += main.cpp #源文件
# The following define makes your compiler emit warnings if you use
# any feature of Qt which as been marked deprecated (the exact warnings
# depend on your compiler). Please consult the documentation of the
# deprecated API in order to know how to port your code away from it.
DEFINES += QT_DEPRECATED_WARNINGS
# You can also make your code fail to compile if you use deprecated APIs.
# In order to do so, uncomment the following line.
# You can also select to disable deprecated APIs only up to a certain version of Qt.
#DEFINES += QT_DISABLE_DEPRECATED_BEFORE=0x060000 # disables all the APIs deprecated before Qt 6.0.0
注意:根据功能的不同,用到的库不同,要在libs下加入相应用到的库
source下的main.cpp
#include <stdio.h>
#include <opencv2/opencv.hpp>
using namespace cv;
int main(int argc, char *argv[])
{
Mat image = imread("E:\\opencv_3.2\\image\\1.jpg"); // 要加
if(NULL == image.data)
{
printf("*******\n");
return -1;
}
namedWindow("image", CV_WINDOW_AUTOSIZE);
imshow("image", image);
waitKey(0);
return 0;
}
这样就可以显示出照片 1.jpg 来。
