Qt+YOLOv4实现目标检测

环境：

系统：win10 （显卡：NVIDIA GTX 1050）

Yolo版本：V4

cuda:11.2

cudnn:8.1.1

opencv:3.4.15

VS:2019

1.编译前准备

    1.1 opencv

    首先要安装opencv，下载地址如下

https://opencv.org/

    安装3.4.16就可以了

    1.2 安装cuda和cudnn

    安装教程可以参考我这篇文章。

2.编译YOLO

    YOLO下载地址：‍

https://github.com/AlexeyAB/darknethttps://codechina.csdn.net/mirrors/alexeyab/darknet?utm_source=csdn_github_accelerator

    用记事本打开yolo_cpp_dll.vcxproj

    将里面的版本换成自己的版本，文件中有两处修改。

    修改完成后，打开yolo_cpp_dll.sln，然后选择release，然后生成。

    生成完后就会得到DLL和LIB。

    然后将头文件和库拷贝到自己工程目录下。

3.构建项目

    3.1 添加头文件路径和库

#OPENCV
INCLUDEPATH += E:/build/include/
INCLUDEPATH += E:/build/include/opencv/
INCLUDEPATH += E:/build/include/opencv2/
LIBS += -LE:/build/x64/vc15/lib/ -lopencv_world3415
​
#YOLO
INCLUDEPATH += $$PWD/yolov4/include/
LIBS += -L$$PWD/yolov4/lib/ -lyolo_cpp_dll

    3.2 添加宏和头文件

//
#define OPENCV
#define GPU
#include "yolo_v2_class.hpp"
​
//
#include 
#include "opencv2/highgui/highgui.hpp"
using namespace cv;

    3.3 要下载这几个文件

    里面有权重文件。
