Optimization of character animation design and motion synthesis in film and television media based on virtual technology

Traditional key frame extraction techniques in animation design and motion synthesis cannot segment high-dimensional action data well, which makes it difficult to achieve some applications that require data segmentation. Combining virtual technology, this paper studies character animation design and motion synthesis in film and television media, and constructs the skeleton model of virtual human body. Based on the selected virtual human key frame states, linear interpolation and quaternion spherical linear interpolation algorithms are used to synthesize real and natural virtual human motion sequences. Through the experimental analysis, we can see that the proposed method is superior to the traditional algorithm in approximate expression ability, and has good animation design and motion synthesis effect.
