我无法理解代码中每个关节的轴是在哪里计算的。
您在Kinect1.0中使用的代码获取BVH文件，通过读取骨骼，使用关节信息构建骨骼矢量。
public static double[] getBoneVectorOutofJointPosition(BVHBone bvhBone, Skeleton skel)
{
double[] boneVector = new double[3] { 0, 0, 0 };
double[] boneVectorParent = new double[3] { 0, 0, 0 };
string boneName = bvhBone.Name;
JointType Joint;
if (bvhBone.Root == true)
{
boneVector = new double[3] { 0, 0, 0 };
}
else
{
if (bvhBone.IsKinectJoint == true)
{
Joint = KinectSkeletonBVH.String2JointType(boneName);
boneVector[0] = skel.Joints[Joint].Position.X;
boneVector[1] = skel.Joints[Joint].Position.Y;
boneVector[2] = skel.Joints[Joint].Position.Z;

除了在Kinect2.0中，骨架类已经被身体类所取代，所以您需要更改它来处理身体，并按照下面引用的步骤获得关节。
// Kinect namespace
using Microsoft.Kinect;
// ...
// Kinect sensor and Kinect stream reader objects
KinectSensor _sensor;
MultiSourceFrameReader _reader;
IList<Body> _bodies;
// Kinect sensor initialization
_sensor = KinectSensor.GetDefault();
if (_sensor != null)
{
_sensor.Open();
}
_reader = _sensor.OpenMultiSourceFrameReader(FrameSourceTypes.Color |
FrameSourceTypes.Depth |
FrameSourceTypes.Infrared |
FrameSourceTypes.Body);
_reader.MultiSourceFrameArrived += Reader_MultiSourceFrameArrived;
始终记得检查空值。Kinect为您提供大约每秒30帧-任何内容都可能是空的或缺失的！以下是到目前为止的代码：
void Reader_MultiSourceFrameArrived(object sender,
MultiSourceFrameArrivedEventArgs e)
{
var reference = e.FrameReference.AcquireFrame();
// Color
// ...
// Depth
// ...
// Infrared
// ...
// Body
using (var frame = reference.BodyFrameReference.AcquireFrame())
{
if (frame != null)
{
_bodies = new Body[frame.BodyFrameSource.BodyCount];
frame.GetAndRefreshBodyData(_bodies);
foreach (var body in _bodies)
{
if (body != null)
{
// Do something with the body...
}
}
}
}
}
就是这里！我们现在可以接触到Kinect识别的尸体。下一步是在屏幕上显示骨架信息。每个身体由25个关节组成。传感器为我们提供位置(X，Y，Z)和每一个的旋转信息。此外，Kinect让我们知道关节是否被跟踪、缩小或没有被跟踪。在执行任何关键功能之前检查身体是否被跟踪是一个很好的做法。
下面的代码说明了如何访问不同的车身关节：
if (body != null)
{
if (body.IsTracked)
{
Joint head = body.Joints[JointType.Head];
float x = head.Position.X;
float y = head.Position.Y;
float z = head.Position.Z;
// Draw the joints...
}
}
