请问你这3DPOSE数据是自己生成的么,我用的单目摄像头做的3DPOSE数据很不稳,显示出来很晃。
师兄您好,我看了github上一些pose转bvh的项目中都会用到您写的类似
x_dir = None
y_dir = pose[index['heel_r']] - pose[joint_idx]
z_dir = pose[joint_idx] - pose[index['knee_r']]
order = 'zxy'
这样的代码,这个和您提到的
对于人体骨骼而言,其自旋仅凭keypoints是无法或者很难精确算出的,需要其他先验知识,在这里就不展开了。
这个是不是有关系,这个x_dir,y_dir,z_dir的设定以及后续的代码我理解的是一个求解新的局部坐标系的过程,然后来据此算出方向余弦矩阵,请问几个*_dir的设计是什么原理呀,我有点理不太清,按照上面那个例子的意思是说ZoY平面始终是由这两段关节组成的这个平面嘛,这个是可以肯定的吗,不会有不一样的情况吗,希望您能给我简单讲一下,麻烦您了,谢谢!
Hello!
First of all, thank you for your great work :)
I am struggling to understand the creation of the standard skeleton here

More specifically, I am struggling to understand what is the thought process for the hands.
For example, why is (7, 30): [3, 0, 1]
