Qt C++使用YOLOV2模型实时检测摄像头视频中的车辆的源代码（CPU检测）

Qt C++使用YOLOV2模型实时检测摄像头视频中的车辆的源代码（CPU检测）
一、主函数

#include <QApplication>
#include <opencv2/opencv.hpp>
#include "dnnvehicledetectclass.h"
using namespace cv;
using namespace std;

int main(int argc, char *argv[]) {
   
    QApplication a(argc, argv);
    DnnVehicleDetectClass dnn;
    VideoCapture cap("rtsp://admin:admin123@192.168.1.108:554/cam/realmonitor?channel=1&subtype=1");
    if (!cap.isOpened()) {
   
        cerr << "Failed to open video stream!" << endl;
        return -1;
    }
    
    Mat frame;
    while (true) {
   
        cap.read(frame);
        if (frame.empty()) {
   
            cerr << "Failed to read frame from video stream!" << endl;
            break;
        }
        dnn.dnnVehicleDetect(frame);
        imshow("Frame", frame);
        
        // Check for ESC key press
        if (waitKey(30) == 27) {
    // 使用 30 毫秒延迟
            break;
        }
    }
    
    // Release resources
    cap.release();
    destroyAllWindows();
    return 0;
}

#include "main.moc"

二、 DnnVehicleDetectClass的头文件

#ifndef DNNVEHICLEDETECTCLASS_H
#define DNNVEHICLEDETECTCLASS_H
#include <QDir>
#include <QString>
#include <QDebug>
#include <QTimer>
#include <direct.h>
#include <QThread>
#include <opencv2/opencv.hpp>
using namespace cv;
using namespace std;

class DnnVehicleDetectClass: public QThread {
   

    Q_OBJECT

public:
    DnnVehicleDetectClass()
