This paper aims to explore the stylization computer-aided design method of Huayao cross-stitch patterns. Firstly, the aesthetic characteristics and production process of Huayao cross-stitch works are analyzed to explore intelligent conversion paths of computer-aided design for cultural prototype stylization. Secondly, collect and sort out the stylization design to establish an image database. Technologies such as artificial intelligence are introduced to segment Huayao cross-stitch patterns and extract the composition and color semantic features from five style types of images，so as to generate new stylization cross-stitch images Finally, the construction process and framework of the computer-aided design system areproposed, which can be used for the design of cultural and creative Huayao cross-stitch works. Huayao cross-stitch work is an important part of China's intangible cultural heritage, which contains rich aesthetic appreciation and cultural connotations. The computer-aided design method proposed in this paper integrates the emotional needs of users into the intelligent design system, enriching innovative design methods of traditional patterns, providing a new way for the inheritance and reuse of Huayao cross-stitch works, and satisfying consumers’ personalized demands for cultural and creative products.
