opencv3.0 - 为什么 opencv_traincascade 失败并显示 : "Train dataset for temp stage can not be filled"?

Question

到目前为止我尝试过的...

opencv_createsamples -info positive/positive.txt -vec positive.vec -w 100 -h 100 -num 2
opencv_createsamples -info negative/negative.txt -vec negative.vec -w 100 -h 100 -num 2
opencv_traincascade -vec positive.vec -data . -bg negative/negative.txt -numPos 1 -numNeg 1 -numStages 1 -w 100 -h 100

# outputs
Train dataset for temp stage can not be filled. Branch training terminated. Cascade classifier can't be trained. Check the used training parameters.

如何用很少的正数训练 HAAR 模型？目标是在 2d 图像中跟踪 2d 图像。

Answer 1

您的论点之一是“numpos”，但根据 http://docs.opencv.org/2.4/doc/user_guide/ug_traincascade.html ，它应该是带有大写 P 的“numPos”。
