Qt+YOLOv4實作目標檢測-有解無憂

環境：

系統：win10 （顯卡：NVIDIA GTX 1050）

Yolo版本：V4

cuda:11.2

cudnn:8.1.1

opencv:3.4.15

VS:2019

1.編譯前準備

1.1 opencv

首先要安裝opencv，下載地址如下

https://opencv.org/

安裝3.4.16就可以了

1.2 安裝cuda和cudnn

安裝教程可以參考我這篇文章，

深度學習GPU環境CUDA安裝教程

2.編譯YOLO

YOLO下載地址：?

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

用記事本打開yolo_cpp_dll.vcxproj

將里面的版本換成自己的版本，檔案中有兩處修改，

修改完成后，打開yolo_cpp_dll.sln，然后選擇release，然后生成，

生成完后就會得到DLL和LIB，

然后將頭檔案和庫拷貝到自己工程目錄下，

3.構建專案

3.1 添加頭檔案路徑和庫

#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 添加宏和頭檔案

//
#define OPENCV
#define GPU
#include "yolo_v2_class.hpp"
?
//
#include <opencv2\opencv.hpp>
#include "opencv2/highgui/highgui.hpp"
using namespace cv;

3.3 要下載這幾個檔案

里面有權重檔案，

密碼：d6lz

3.4 最后運行程式

結果如下：
