Kinect-based body shape adaptive three-dimensional virtual human body model building method and animation system

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.

Description

technical field [0001] The invention relates to the fields of computer image processing and computer graphics, in particular to a Kinect-based body shape self-adaptive three-dimensional virtual human model construction method and an animation system. Background technique [0002] In recent years, virtual reality technology has become popular. Virtual reality technology is based on computer technology, through which one or more sensor devices can create a "virtual world" environment, allowing users to immerse themselves in it and interact with it. Virtual reality technology can provide users with visual, auditory, and tactile sensations, so that users have a feeling of being on the scene. [0003] 3D virtual human animation has a wide range of applications in industries such as games and movies. Generally, commercial animation software such as Maya and 3DMax can produce 3D virtual human animations, but the use of these software is complex and requires a lot of work. The use...

AI Technical Summary

Problems solved by technology

Generally, commercial animation software such as Maya and 3DMax can produce 3D virtual human animations, but the use of these software is complex and requires a lot of work. The use process relies on previous experience, and it is difficult to get started. Professionals are often required to operate

Human body modeling and animation production process require a lot of human-computer interaction, and the computer can only support graphics drawing and display, which requires a lot of energy for animators

If there are animated characters of different sizes in the animation, different animated character models need to be provided, and the animation reuse rate produced in this way is not high. If you want to change the action of the 3D virtual human, you need to recreate a set of animations
