|dc.title||Personalized 3D human body modelling and real-time motion tracking based on kinect v2||en_US|
|dcterms.abstract||With the coming of network information technology times, 3D virtual human modelling techniques have been utilized extensively in the fields of computer vision, film and television production, game designing, etc. So how to obtain a more realistic 3D virtual human model, and track the person's motion in real time effectively, are the research targets and hot topic in the area of computer graphics and computer vision currently. And the virtual human model is a technology branch of virtual reality. It can emulate the human body to do a variety of perilous experiment. And the real-time motion tracking technology can be used in virtual fitting, virtual meeting and some other areas. Therefore, the research of studying 3D human body modelling and real-time motion tracking has sufficient theoretical significance and practical value. This dissertation proposed a method of 3D human body modelling and then realize real-time motion tracking based on Unity3D. This method use Kinect v2 sensor to capture the raw data and then the mesh model is created by three steps: point cloud generation, Point cloud registration and model surface reconstruction. After the human body model reconstructed, some problems in the mesh model need to be solved. The holes in the model is filled based on minimum angle algorithm. Finally, the optimized 3D human body model is finished. Then, this dissertation proposed a method of real-time motion tracking. It firstly designs a virtual skeleton for the mesh model and then set the weight of each joints in the skeleton. Secondly, it combines the skeleton inside the model to the skeleton detected by the Kinect v2 sensor to realize real-time motion tracking. Finally, the 3D human body model can track the motion of the person in real time based on Unity3D. Lastly, this dissertation develops a simple application about virtual fitting. A blue T-shirt is designed and then combined with the skeleton inside the human body model. Then, the human model with blue T-shirt is put into the project. The people can see the dress look in any perspective they want. The experimental result show that, through the reconstruction of the model and the optimization process, we can acquire a more realistic virtual human body model. At the same time, the real-time motion tracking also performs good.||en_US|
