躯干联合方向 [英] Trunk joint orientation

问题描述

你好，

我很难理解躯干关节的方向。这是我的两个问题：

I'm in difficulty trying to understand the orientation of the joints of the trunk. Here are my 2 questions:

- 我注意到整个脊柱的方向基本相同（spineShoulder和spineMid的方向相同）...我可以问你为什么？显然，实际上这两个部分通常有不同的方向...也许系统
无法正确读取他们的方向？或者它只是一个skd bug？

- I've noticed that the orientation of the whole vertebral column is substantially the same (same orientation for spineShoulder and spineMid)... can I ask you why? obviously in reality these two segments have usually different orientations... maybe the system can't read correctly their orientation? or is it just a skd bug?

- 我已经明白使用jointOrientation函数，我可以读取作为参数传递的关节和它的父级之间包含的骨骼的方向...这样对吗？那么，我可以问你指令的含义是什么：  jointOrientation（spineBase）？
它已经是根关节了，所以我无法理解它指的是哪个骨头...

- I've understood that using jointOrientation function, I can read the orientation of the bone included between the joint passed as parameter and its parent... is it right? so, can I ask you which is the meaning of the instruction: jointOrientation(spineBase)? it's already the root joint, so I can't understand which bone it refers to...

我正在回复你。

谢谢。

问候。

推荐答案

背面的方向可以是推断为没有真正移动那么多，因为当你看着身体时，它通常是一条直线。您可以根据联合信息推断出一些ben信息。有关 方向的更多信息，请访问此主题：$ a href ="https://social.msdn.microsoft.com/Forums/en-US/245a3a09-a2e4-4e0e-8c12-b8625102376a/kinect -v2-sdk-joint-orientation？forum = kinectv2sdk">

spineBase没有父级。它的方向取决于与相机的关系。

There is no parent to spineBase. It's orientation is based on the relation to the camera.
