kinect骨骼关节的相对跟踪？ [英] Relative tracking of a kinect skeleton joint ?

问题描述

您好，

目前我正在使用Coding4fun ScaleTo（）跟踪右手，如下所示：

Currently I am using Coding4fun ScaleTo() to track the right hand , like this :

Joint scaledJoint = joint.ScaleTo(1920, 1080, .3f, .3f);
System.Drawing.Point p = new System.Drawing.Point(Convert.ToInt32(scaledJoint.Position.X), Convert.ToInt32(scaledJoint.Position.Y));
MouseLibrary.SetCursorPosition(p);

我想通过使用相对于我头部的右手的相对跟踪来改善这一点。 

I would like to improve this by using relative tracking of my right hand relative to my head. 

例如，如果我蹲下，鼠标光标不会改变，因为我的头手关系是相同的。

For example, if I crouched down, the mouse cursor would not change because my head-hand relationship is the same.

有什么建议吗？

谢谢，彼得

推荐答案

您可以创建一个虚拟屏幕，其边缘从您的头部开始，作为虚拟屏幕的零位置。

You could create a virtual screen its edges starts from you head as the zero based position of your virtual screen.

使您的手相对于您的手位置从零位置（ （点头）你可以减去手的Position.X - 你头部的Position.X也是Y位置并尝试将这一点相对于屏幕上的光标点

To get your hand position relative to you zero based position (the head point) you can subtract your Position.X of your hand - Position.X of your head also the Y position and try to relative this point to the cursor point on the screen

试试这个它通过其他方式得到屏幕点

try this it get the screen point but by other way

/// <summary>
/// Updates the cursor position.
/// </summary>
/// <param name="hand">The hand.</param>

private void SetCursor(Joint hand, Joint head)
        {
            var point = _kinectSensor.MapSkeletonPointToDepth(head.Position, _kinectSensor.DepthStream.Format);

            float x = point.X;
            float y = point.Y;
            float z = point.Depth;

            x = (float)(x * _window.ActualWidth / _kinectSensor.DepthStream.FrameWidth);
            y = (float)(y * _window.ActualHeight / _kinectSensor.DepthStream.FrameHeight);
            x += ((float)(_window.ActualWidth * hand.Position.X * 4));

            y -= ((float)(_window.ActualHeight * hand.Position.Y * 3));

            Point cursorPoint = new Point(x, y);
        }
