Question & Answer :
I would similar to shop the question seizure information from Kinect 2 arsenic a BVH record. I recovered codification which does truthful for Kinect 1 which tin beryllium recovered present. I went done the codification and recovered respective issues that I was not capable to realize. For illustration, successful the talked about codification I’ve tried to realize what precisely the Skeleton skel entity, recovered successful respective locations successful the codification, really is. If not, are location immoderate identified exertion disposable to execute the supposed?
EDIT: I tried to alteration Skeleton skel to Assemblage skel which I deliberation is the correspondant entity for kinect SDK 2.zero. Nevertheless I’ve bought an mistake once I attempt to acquire the assumption of the assemblage:
tempMotionVektor[zero] = -Mathematics.Circular( skel.Assumption.X * one hundred,2); tempMotionVektor[1] = Mathematics.Circular( skel.Assumption.Y * one hundred,2) + a hundred and twenty; tempMotionVektor[2] = 300 - Mathematics.Circular( skel.Assumption.Z * one hundred,2);
I’ve gotten errors once calling the relation Assumption for the Assemblage skel. However tin I retrieve the X, Y, Z of the skeleton successful sdk 2.zero?? I tried to alteration the supra 3 strains to:
tempMotionVektor[zero] = -Mathematics.Circular(skel.Joints[zero].Assumption.X * a hundred, 2); tempMotionVektor[1] = Mathematics.Circular(skel.Joints[zero].Assumption.Y * one hundred, 2) + one hundred twenty; tempMotionVektor[2] = 300 - Mathematics.Circular(skel.Joints[zero].Assumption.Z * one hundred, 2);
EDIT: Fundamentally I managed to shop the a bvh record last combining bodyBasicsWPF and kinect2bvh. Nevertheless, it appears that the skeleton I americium storing is not businesslike. Location are unusual actions successful the elbows. I americium making an attempt to realize if I person to alteration thing successful the record kinectSkeletonBVH.cp. Much particularly, what are the adjustments successful the associated axis predisposition for the kinect 2 interpretation. However tin I alteration the pursuing formation: skel.BoneOrientations[JointType.ShoulderCenter].AbsoluteRotation.Quaternion; I tried to alteration that formation with skel.JointOrientations[JointType.ShoulderCenter].Predisposition. Americium I correct? I americium utilizing the pursuing codification to adhd the associated to BVHBone objects:
BVHBone hipCenter = fresh BVHBone(null, JointType.SpineBase.ToString(), 6, TransAxis.No, actual); BVHBone hipCenter2 = fresh BVHBone(hipCenter, "HipCenter2", three, TransAxis.Y, mendacious); BVHBone backbone = fresh BVHBone(hipCenter2, JointType.SpineMid.ToString(), three, TransAxis.Y, actual); BVHBone shoulderCenter = fresh BVHBone(backbone, JointType.SpineShoulder.ToString(), three, TransAxis.Y, actual); BVHBone collarLeft = fresh BVHBone(shoulderCenter, "CollarLeft", three, TransAxis.X, mendacious); BVHBone shoulderLeft = fresh BVHBone(collarLeft, JointType.ShoulderLeft.ToString(), three, TransAxis.X, actual); BVHBone elbowLeft = fresh BVHBone(shoulderLeft, JointType.ElbowLeft.ToString(), three, TransAxis.X, actual); BVHBone wristLeft = fresh BVHBone(elbowLeft, JointType.WristLeft.ToString(), three, TransAxis.X, actual); BVHBone handLeft = fresh BVHBone(wristLeft, JointType.HandLeft.ToString(), zero, TransAxis.X, actual); BVHBone cervix = fresh BVHBone(shoulderCenter, "Cervix", three, TransAxis.Y, mendacious); BVHBone caput = fresh BVHBone(cervix, JointType.Caput.ToString(), three, TransAxis.Y, actual); BVHBone headtop = fresh BVHBone(caput, "Headtop", zero, TransAxis.No, mendacious);
I tin’t realize wherever wrong the codification the axis for all Associated is calculated.
The codification you utilized for Kinect 1.zero to get a BVH record usage the joints accusation to physique bony vectors by speechmaking the Skeleton.
national static treble[] getBoneVectorOutofJointPosition(BVHBone bvhBone, Skeleton skel) { treble[] boneVector = fresh treble[three] { zero, zero, zero }; treble[] boneVectorParent = fresh treble[three] { zero, zero, zero }; drawstring boneName = bvhBone.Sanction; JointType Associated; if (bvhBone.Base == actual) { boneVector = fresh treble[three] { zero, zero, zero }; } other { if (bvhBone.IsKinectJoint == actual) { Associated = KinectSkeletonBVH.String2JointType(boneName); boneVector[zero] = skel.Joints[Associated].Assumption.X; boneVector[1] = skel.Joints[Associated].Assumption.Y; boneVector[2] = skel.Joints[Associated].Assumption.Z; ..

But successful Kinect 2.zero, Skeleton people has been changed by the Assemblage people, truthful you demand to alteration it to woody with a Assemblage alternatively, and get the joints by pursuing the steps quoted beneath.
// Kinect namespace utilizing Microsoft.Kinect; // ... // Kinect sensor and Kinect watercourse scholar objects KinectSensor _sensor; MultiSourceFrameReader _reader; IList<Assemblage> _bodies; // Kinect sensor initialization _sensor = KinectSensor.GetDefault(); if (_sensor != null) { _sensor.Unfastened(); }We besides added a database of our bodies, wherever each of the assemblage/skeleton associated information volition beryllium saved. If you person developed for Kinect interpretation 1, you announcement that the Skeleton people has been changed by the Assemblage people. Retrieve the MultiSourceFrameReader? This people offers america entree connected all watercourse, together with the assemblage watercourse! We merely demand to fto the sensor cognize that we demand assemblage monitoring performance by including an further parameter once initializing the scholar:
_reader = _sensor.OpenMultiSourceFrameReader(FrameSourceTypes.Colour | FrameSourceTypes.Extent | FrameSourceTypes.Infrared | FrameSourceTypes.Assemblage); _reader.MultiSourceFrameArrived += Reader_MultiSourceFrameArrived;The Reader_MultiSourceFrameArrived technique volition beryllium referred to as every time a fresh framework is disposable. Ftoโs specify what volition hap successful status of the assemblage information:
- Acquire a mention to the assemblage framework
- Cheque whether or not the assemblage framework is null โ this is important
- Initialize the _bodies database
- Call the GetAndRefreshBodyData methodology, truthful arsenic to transcript the assemblage information into the database
- Loop done the database of our bodies and bash superior material!
Ever retrieve to cheque for null values. Kinect offers you with about 30 frames per 2nd โ thing may beryllium null oregon lacking! Present is the codification truthful cold:
void Reader_MultiSourceFrameArrived(entity sender, MultiSourceFrameArrivedEventArgs e) { var mention = e.FrameReference.AcquireFrame(); // Colour // ... // Extent // ... // Infrared // ... // Assemblage utilizing (var framework = mention.BodyFrameReference.AcquireFrame()) { if (framework != null) { _bodies = fresh Assemblage[framework.BodyFrameSource.BodyCount]; framework.GetAndRefreshBodyData(_bodies); foreach (var assemblage successful _bodies) { if (assemblage != null) { // Bash thing with the assemblage... } } } } }This is it! We present person entree to the our bodies Kinect identifies. Adjacent measure is to show the skeleton accusation connected-surface. All assemblage consists of 25 joints. The sensor gives america with the assumption (X, Y, Z) and the rotation accusation for all 1 of them. Furthermore, Kinect lets america cognize whether or not the joints are tracked, hypothsized oregon not tracked. Itโs a bully pattern to cheque whether or not a assemblage is tracked earlier performing immoderate captious capabilities.
The pursuing codification illustrates however we tin entree the antithetic assemblage joints:
if (assemblage != null) { if (assemblage.IsTracked) { Associated caput = assemblage.Joints[JointType.Caput]; interval x = caput.Assumption.X; interval y = caput.Assumption.Y; interval z = caput.Assumption.Z; // Gully the joints... } }
