This paper aims to study and analyze the development difficulties of Qiang embroidery in inheritance, innovation consciousness, and low degree of industrialization, proposing a service design model of Qiang embroidery based on digital protection and industrial application. Through the integration of online and offline resources and the establishment of Qiang embroidery application platform, it can meet the learning and sales needs of the embroiderers and Qiang embroidery enthusiasts, and realize the rapid development of Qiang embroidery. The improved SIFT stitch pattern feature extraction method was used to realize AI stitch recognition; shape grammar and image stitching algorithm were used to realize DIY pattern design; qualitative and quantitative user research methods were used to analyze the needs of target groups in the experience of Qiang embroidery and transformed them into specific functions of the Qiang embroidery service design platform. The different use needs and use processes of embroiderers and Qiang embroidery enthusiasts were reviewed; two mobile terminal modes of embroiderers and Qiang embroidery enthusiasts were established; the corresponding information architecture and human-computer interface were designed, and finally the interactive prototype improved were evaluated with the improved overall evaluation availability questionnaire. The service design platform of Qiang embroidery for realizing the digital protection and industrial application of Qiang embroidery is built, and it can change the teaching and inheritance mode of Qiang embroidery, and provide diversified sales channels, and improve the industrialization model of Qiang embroidery by introducing machine embroidery, and realize the digital protection and inheritance of Qiang embroidery.
