我目前正在尝试训练HaarCascade分类器。我到达了训练过程正在运行的地步,并且我能够训练至少一个“工作”的分类器。这将正确检测很多。现在,我试图通过添加更多的正样本和负样本来改善结果。
由于分类器在很多时候都在工作,因此我决定让它在测试数据集上运行并裁剪出正面分类的图像。这些裁剪的图像由我手动清除。我现在想将这些新的正面图像添加到我的训练数据集中。
开始另一次训练后,我遇到以下错误:
POS电流样本:166 POS电流样本:167 POS电流样本: 168 POS OpenCV错误:错误的参数(无法获取新的正样本。 最可能的原因是给定样本数量不足 vec文件。 )在CvCascadeImageReader :: PosReader :: get文件中 D:\ cv \ opencv_3.2.0 \ sources_withTextModule \ apps \ traincascade \ imagestorage.cpp, 158行
包括opencv调用的所有参数。我还缩短了相对路径以提高可读性。

这是我第一次尝试,我仍在做很多尝试,因此有些事情可能会出错,但是我不确定,所以我想我可以在这里添加这些内容,以供认识的人确认这些东西。
