[人工智能]QT中使用openCV

1. 新建一个qmainwindow工程
2. 准备好opencv的库，放在工程目录下

3. .pro文件增加：
   CONFIG(debug, debug|release) {
   LIBS += KaTeX parse error: Expected 'EOF', got '}' at position 41: …/libopencv_*.a }? else { LIBS +=…PWD/opencv4/x86/mingw/lib/libopencv_*.a
   }

INCLUDEPATH += ./opencv4/include/opencv2
INCLUDEPATH += ./opencv4/include
4.
工程中增加代码：
#include “mainwindow.h”
#include “ui_mainwindow.h”

#include"core.hpp"
#include <highgui.hpp>
#include <imgproc.hpp>
using namespace cv;

MainWindow::MainWindow(QWidget *parent)

QMainWindow(parent)
, ui(new Ui::MainWindow)
{
ui->setupUi(this);

cv::Mat image = imread(“F:\00QTwork\026_algrith\04_libs\opencv_testAPP\testJpg\testCV.jpg”,1);
namedWindow(“disp win”, WINDOW_AUTOSIZE );
if(!image.empty())
{
imshow( “disp win”,image);
}

}

MainWindow::~MainWindow()
{
delete ui;
}

5. 增加一个测试图片
