Character Motion Rendering System Based On Kinect

With the rapid development of science and technology,Kinect's sensory technology is becoming more and more mature,and has been widely used in various fields because of its low cost and good functional effect.For example,there are a large number of motion capture devices and virtual reality VR devices in the Science and Technology Museum for children to learn new knowledge and entertainment.Kinect captures accurate skeletal data,but there are errors.This paper studies the bone prediction algorithm and the lost joint repair algorithm,and optimizes the bone data obtained by Kinect.The data error is reduced,and smoothing technology is added to prevent skeletal edge from shaking.Finally,motion redirection technology is used to reduce the distortion of the role model,which is successfully imported into the Unity3 D virtual scene to achieve action synchronization between virtual human and real human.Through the study of the above problems,a Kinect-based human action rendering system is developed.On this basis,combined with the virtual scene of the construction site,the fire rescue drill of workers is simulated,which provides a train of thought and direction for the application of this research,and makes the research have a good application prospect.
