【opencv 级联分类器】合并已训练的stage#.xml为一个cascade.xml

已经训练了好几天，想停止级联分类器的训练，然后将已训练的stage0-7.xml文件组合成cascade.xml文件

停止训练之后，找到opencv_traincascade.exe所在目录，然后拷贝到 classifier文件夹所在文件夹下。

可以从build程序的x64\bin文件夹下找到

拷贝到这里

然后shift+右键 打开PowerShell，运行一下代码：

opencv_traincascade.exe -data D:\test\blocks\classifier2 -vec D:\test\blocks\pos_samples.vec -bg D:\test\blocks\neg.lst -numPos 2633 -numNeg 8748 -numStages 8 -precalcValBufSize 1024 -precalcIdxBufSize 1024 -featureType LBP -w 24 -h 24

D:\test\blocks> opencv_traincascade.exe -data D:\test\blocks\classifier2 -vec D:\test\blocks\pos_samples.vec -bg D:\test\blocks\neg.lst -num
Pos 2633-numNeg 8748 -numStages 8 -precalcValBufSize 1024 -precalcIdxBufSize 1024 -featureType LBP -w 24 -h 24
D:\test\blocks> opencv_traincascade.exe -data D:\test\blocks\classifier2 -vec D:\test\blocks\pos_samples.vec -bg D:\test\blocks\neg.lst -numPos 2633 -numNeg
 8748 -numStages 8 -precalcValBufSize 1024 -precalcIdxBufSize 1024 -featureType LBP -w 24 -h 24

运行完毕后可以得到cascade.xml

 级联分类器训练 stop后 合并stage#.xml为 cascade.xml
