The purpose of this paper is to analyze the elements of the female image characteristics in the trademarks of the Republic of China from the designer's perspective and choose the design method. Taking the female image trademark of the Republic of China as the research object, and quantification theory I as the basis, use the semantic difference method to obtain the designer's perceptual evaluation on the female image trademark modeling of the Republic of China, and then from the female visual image, subject selection, expression method, cultural connotation, etc., extract the key modeling design elements that affect the perceptual image, and construct the correlation model between the perceptual image and the female image trademark design elements of the Republic of China through the quantitative theory I. The selection of different design elements of the designers in the Republic of China has different effects on the expression of the female image trademark image of the Republic of China. The perceptual image vocabulary shows a tendency to choose the level of specific design elements. There is a correlation between the perceptual image in the female image trademark of the Republic of China and the designer's choice on design elements. The establishment of the model shows that this method can effectively describe the perceptual image expression of the female image trademark design in the Republic of China, so as to provide reference for the current female image design in the trademark.
