Research On Sign Language Animation Key Frame Editing And Interpolation Base On Movment Characteristics

Key frame animation is a kind of computer animation method. This method calculates frames between two key frames automatically according to kinematics and kinetics. The method compresses memory size of animation data through building complex movement with few simple key frames. As a result, the key frame animation is widely used for computer animation, especially the human animation. However, key frame animation causes loss of movement detail information, while creating animation with key frames. In order to make animation having more detail information, researchers advance many kinds of key frame extraction program. This paper researches method of key frame editing and interpolation for human animation motion detail enhancement.Firstly, this paper advances human upper limb joint movement data acquisition method. Cyber Glove and Fastrack Postion Tracker are used during real-time movement capture. Then this paper provides the method of data processing detials and implementation according to Wang's article. Later, the paper gives a 3D guesture editing program, which is easily used by staff to edit existed sign language data and correct the wrong one. At last, this paper analyzes sign language data and advances a hierarchical interpolation method based on key frame style. As a result, a human animation with detail information is generated by this interpolation method.
