Abstract
The invention discloses a Kinect-based body shape adaptive three-dimensional virtual human body model building method. The method comprises the steps of acquiring color and depth images by utilizing Kinect; recognizing a human body from the images; extracting joint point data of the human body; performing smoothing operation on the joint point data of the human body; extracting the hip width and the body height of the real human body in the depth image; calculating a proportionality coefficient of body shape data of the real human body and a standard human body; adjusting a virtual human bodymodel through the proportionality coefficient; calculating a rotation matrix between skeletons; and performing skeleton movement and skin operation on the virtual human body model, and rendering the updated three-dimensional virtual human model. Correspondingly, the invention further provides a Kinect-based body shape adaptive three-dimensional virtual human body animation system. By utilizing a human body joint point recognition technology, a skeleton animation technology and a virtual reality technology of the Kinect, the three-dimensional virtual human body model suitable for the body shapeof the real human body is built, and the Kinect can be used for driving the virtual human body model to move; and the sense of reality can be enhanced, so that the user experience is greatly improved.
