opencv - 如何用opencv编译YOLOv3？

Question

我想使用YOLOv3在macOS 10.14.1的视频中进行对象检测
因此，我安装了opencv 4.0.1

brew install opencv

换了线

OPENCV=0

至

OPENCV=1

在Darknet Makefile中

然后，我指定了pkgconfig链接

 export PKG_CONFIG_PATH=/usr/local/lib/pkgconfig

并重新编译

make

g++ -Iinclude/ -Isrc/ -DOPENCV `pkg-config --cflags opencv`  -Wall -Wno-unused-result -Wno-unknown-pragmas -Wfatal-errors -fPIC -Ofast -DOPENCV -c ./src/image_opencv.cpp -o obj/image_opencv.o
Package opencv was not found in the pkg-config search path.
Perhaps you should add the directory containing `opencv.pc'
to the PKG_CONFIG_PATH environment variable
No package 'opencv' found
./src/image_opencv.cpp:5:10: fatal error: 'opencv2/opencv.hpp' file not found
#include "opencv2/opencv.hpp"

我应该了解YOLOv3仅适用于openCV 2.0吗？

使用OpenCV 4，我们需要修改Makefile:
将pkg-config名称从opencv修改为opencv4:

LDFLAGS+= `pkg-config --libs opencv4` -lstdc++
COMMON+= `pkg-config --cflags opencv4`
