如何提升识别的精度 #27

您好,我有几点疑问想向您请教一下,因为我现在的识别精度很低
1.数据集训练时需要每个类别穿插开吗?还是不影响,我看您的marked_pictrain.txt文件中每个类别是穿插着标注的,而我的训练集里是一个类别一起标注排列,再开始下一个类别,不知道是否这个会影响精度
2.数据集达到什么样的量级才能达到您说的精度呢,目前我的每个类别才标注了10来张,不知道是不是数据量太小也会有影响
3.实际采集时摄像头位置角度和准备训练样本时的摄像头角度位置不一样是否也会使人体骨架产生畸变,从而影响识别精度?
以上是我的几点疑问,麻烦您有空的时候帮忙解答一下,谢谢啦

我感觉主要问题是数据集太少了的原因,相信每个达到50张以上才有可观的效果

1.应该不影响,但你可以试试打乱或者重写dataset方法用shuffle参数;
2.;
3.数据多了之后应该角度和距离不会有太大影响,数据集太少可能会过拟合之类的。
