绘制2个跟踪骨架Kinect SDK v1.6的最接近的骨骼（肩部 - 头部） [英] Draw the closest Bone (Shoulder - Head) of 2 tracking skeletons Kinect SDK v1.6

问题描述

您好，我正在寻找一种解决方案来绘制最近骨架的骨骼。我编写了代码来绘制第一个跟踪骨架的骨骼。如果第二个人比第一个人更接近我想画第二个骨架的骨头。也许有人知道怎么做
呢？

Hello, I'm looking a solution to draw the bone of the closest skeleton. I wrote code to draw the first tracking skeleton's bone. If the second person will closer than first I want to draw bone of second skeleton. Maybe somebody have any idea how to do it?

 void sensor_SkeletonFrameReady(object sender, SkeletonFrameReadyEventArgs e)
        {
            using (SkeletonFrame skeletonFrame = e.OpenSkeletonFrame())
            {
                // check for frame drop.
                if (skeletonFrame == null)
                {
                    return;
                }
                // copy the frame data in to the collection
                skeletonFrame.CopySkeletonDataTo(totalSkeleton);

                // get the first Tracked skeleton
                skeleton = (from trackskeleton in totalSkeleton
                                      where trackskeleton.TrackingState == SkeletonTrackingState.Tracked
                                      select trackskeleton).FirstOrDefault();

                
                if (skeleton != null)
                {
                    if (skeleton.Joints[JointType.ShoulderCenter].TrackingState == JointTrackingState.Tracked && skeleton.Joints[JointType.Head].TrackingState == JointTrackingState.Tracked)
                    {
                        myCanvas.Children.Clear();
                        this.DrawHead();
                    }
                }
            }
        }

        // Draws the head.
        private void DrawHead()
        {
            if (skeleton != null)
            {
                drawBone(skeleton.Joints[JointType.ShoulderCenter], skeleton.Joints[JointType.Head]);
            }
        }


        // Draws the bone.
        void drawBone(Joint trackedJoint1, Joint trackedJoint2)
        {
            Line skeletonBone = new Line();
            skeletonBone.Stroke = Brushes.Black;
            skeletonBone.StrokeThickness = 3;

            Point joint1 = this.ScalePosition(trackedJoint1.Position);
            skeletonBone.X1 = joint1.X;
            skeletonBone.Y1 = joint1.Y;

            Point joint2 = this.ScalePosition(trackedJoint2.Position);
            skeletonBone.X2 = joint2.X;
            skeletonBone.Y2 = joint2.Y;

            myCanvas.Children.Add(skeletonBone);
        }

        /// <summary>
        /// Scales the position.
        /// </summary>
        /// <param name="skeletonPoint">The skeltonpoint.</param>
        /// <returns></returns>
        private Point ScalePosition(SkeletonPoint skeletonPoint)
        {
            // return the depth points from the skeleton point
            DepthImagePoint depthPoint = this.sensor.CoordinateMapper.MapSkeletonPointToDepthPoint(skeletonPoint, DepthImageFormat.Resolution640x480Fps30);
            return new Point(depthPoint.X, depthPoint.Y);
        }

    }
}

请参阅"如何选择要跟踪的用户"

如果您查看SDK工具包中的Kinect Explorer示例，有几种设置主动跟踪的方法

If you look at the Kinect Explorer samples in the SDK Toolkit, there are several ways of setting up active tracking
