Starting from the research on the characteristics of sugar sculpture, the paper aims to put forward a new strategy of the image of sugar sculpture to promote the development of sugar sculpture. According to the existing data, the lion modeling with typical characteristics in Tianmen sugar sculpture was selected as the research object, and its color, shape, texture and composition elements were extracted and analyzed. Combined with the analysis results, CGM model was used to guide the innovation and redesign. The use of CGM model can retain the characteristics of Tianmen sugar sculpture, innovate and expand new modeling on this basis, provide an exploration direction for the further development of Tianmen sugar sculpture, provide a new idea for other intangible cultural heritage, and widen the possibility of the integration of intangible cultural heritage and modern design.
