我正在尝试使用haar training训练级联。我使用了以下参数。
C:\opencv\opencv_bin\bin>opencv_haartraining -data haar -vec train.vec -bg neg.
txt -numPos 1000 -numNeg 2000 -nstages 10 -mem 2000 -mode all -w 30 -h 32
但是我收到以下错误

我正在使用一个包含1000个样本的vec文件，我从互联网上下载了2000个样本。
答案 0 :(得分：0)
“Vec文件样本大小不匹配” - 尝试检查网站的样本大小。 vec文件可能不是30x32图像（您尝试传递的图像为-w 30 -h 32）。
这只是猜测。试试吧。并尝试使用traincascade对象。它在$ OpencvDir $ / apps / traincascade /中。像任何其他对象一样编译它。它也可以用于LBP和HOG。
希望这有帮助。

w和h的比率与info.txt中的设置不同。您应该在info.txt int 30:32中修改所有图像的w和h。
