Yolov4-darknet批量测试并保存图片
采用的代码是YOLOV4官方源码，地址为：https://github.com/AlexeyAB/darknet
论文链接：https://arxiv.org/abs/2004.10934
具体的配置和训练到检测可以参考我的上一篇博客：YOLOV4训练自己的数据集—从环境配置到完成检测任务（Windows）
这篇主要是针对在批量测试时，我们可能有一种需求就是：将批量检测完成后的图片保存到自己的文件夹中，同时检测的标签以文本文件的方式存储。（也可以看这个代码）
首先在源码文件夹中找到src/detector.c源文件 将detector.c的test_detector函数整体替换，然后重新编译darknet，生成新的darknet.exe文件。控制台测试命令：darknet.exe detector test data/obj.data cfg/yolo-obj.cfg backup/yolo-obj_final.weights data/test.txt -save_labels
注意将yolo-obj.cfg配置文件中的batch及subdivison设为1， data/test.txt为测试图片路径，检测完成后的图片保存在你测试图片的文件夹下的最终结果目录中。使用-save_labels这个命令会在结果目录中生成一个文本文件，保存的是检测的结果类别和坐标信息。
