Adjustment Design of Motion Rhythm of 3D Animation Based on Feature Extraction and Recognition

With the promotion of social development and the arrival of modern information technology, the computer hardware and software technology have developed rapidly, and the efficiency of animation production has been continuously improved until the emergence of 3D animation. There are two trends in three-dimensional animation teaching: action design and modeling form. The design and modeling of characters in design largely determines the popularity of an animation work. In three-dimensional animation, the law of character movement is a kind of animation artistic expression with both artistic expression and technical operation. The law of motion is the basis of all actions, and it is the basis of action in the process of character action design. In this paper, the characteristics of character movements in animation are analyzed, and the methods to improve character animation skills are put forward. Based on feature extraction and recognition technology, this paper analyzes the adjustment design of characters' movement rhythm in 3D animation, and explores the key points of characters' movement design in 3D animation.
