【问题描述】:
我正在开发一个带有 kinect 设备的手势应用程序。这里我用 X,y,z 坐标检查手势。
我想知道特定手势的骨架性质。我正在检查手势是否是手推。
private handpush()
{
bool MovedFront = false;
float refDistance = 0.2F;
SkeletonPoint refPos = SkeletonHistory[0].Joints[JointType.ShoulderCenter].Position;
SkeletonPoint startPos = SkeletonHistory[0].Joints[JointType.HandRight].Position;
//printing all intial cordinates
Console.WriteLine(" ShoulderCenter[0].Z = " + refPos.Z);
Console.WriteLine(" HandRight[0].X = " + startPos.X);
Console.WriteLine(" HandRight[0].Y = " + startPos.Y);
Console.WriteLine(" HandRight[0].Z = " + startPos.Z);
for (int i = 20; i < SkeletonHistory.Count; i++)
{
Console.WriteLine(" ShoulderCenter[i].Z = " + SkeletonHistory[i].Joints[JointType.ShoulderCenter].Position.Z);
Console.WriteLine(" HandRight[i].X = " + SkeletonHistory[i].Joints[JointType.HandRight].Position.X);
Console.WriteLine(" HandRight[i].Y = " + SkeletonHistory[i].Joints[JointType.HandRight].Position.Y);
Console.WriteLine(" HandRight[i].Z = " + SkeletonHistory[i].Joints[JointType.HandRight].Position.Z);
if (!(SkeletonHistory[i].Joints[JointType.HandRight].Position.Y < SkeletonHistory[i].Joints[JointType.Head].Position.Y &&
Math.Abs(SkeletonHistory[i].Joints[JointType.ShoulderCenter].Position.Z - refPos.Z) < 0.05F &&
Math.Abs(SkeletonHistory[i].Joints[JointType.HandRight].Position.Y - startPos.Y) < 0.1F &&
Math.Abs(SkeletonHistory[i].Joints[JointType.HandRight].Position.X - startPos.X) < 0.1F))
{
Console.WriteLine("CheckHandPush breaking !!");
break;
}
if (SkeletonHistory[i].Joints[JointType.HandRight].Position.Z <= (startPos.Z - refDistance))
{
Console.WriteLine("CheckHandPush sucess");
bMovedFront = true;
temp_SkeletonHistory.Clear();
}
}
return MovedFront;
}
但我得到的初始值如下:
输出:
ShoulderCenter[0].Z = 1.246491
HandRight[0].X = 0.1519185
HandRight[0].Y = -0.2328865
HandRight[0].Z = 1.014945
ShoulderCenter[i].Z = 1.248788
HandRight[i].X = 0.1397971
HandRight[i].Y = -0.2452036
HandRight[i].Z = 1.054223
-----
ShoulderCenter[0].Z = 1.26865
HandRight[0].X = 0.1545139
HandRight[0].Y = -0.3375102
HandRight[0].Z = 1.057466
ShoulderCenter[i].Z = 1.25049
HandRight[i].X = 0.09602752
HandRight[i].Y = -0.283217
HandRight[i].Z = 1.150237
---
ShoulderCenter[0].Z = 1.243356
HandRight[0].X = 0.1406149
HandRight[0].Y = -0.2458241
HandRight[0].Z = 1.065399
ShoulderCenter[i].Z = 1.250542
HandRight[i].X = 0.1392216
HandRight[i].Y = -0.2418006
HandRight[i].Z = 1.046706
我在推动我的手,那么Z轴应该增加值还是减少值?表示Z坐标长度是从kinect设备还是人体开始?
这种条件适合手推吗?有什么建议 ?我可以得到一个示例代码吗??
有任何有用的链接来检查手推、手拉的 x、y、z 坐标吗?
我对坐标检查感到困惑。
