一、是什么
从YOLOv1到YOLOv3，目标检测的进化之路
实时目标检测， mAP
FPS,Frames Per Second 每秒传输帧数
mAP (mean Average Precision) 平均精度
IOU？
不用什么框架，完全C语言，NB大发了。

二、run起来
We didn't compile Darknet with OpenCV so it can't display the detections directly. ?
编译GPU版本？https://pjreddie.com/darknet/install/#cuda

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
