| In order to solve the problem of insufficient design service ability of Miao embroidery derivative products,this paper puts forward a CMF-driven auxiliary design method of Miao embroidery derivative products.By studying the correlation between users’ image cognition and Miao embroidery cultural elements,combining Miao embroidery traditional culture with color,material and craft(color,material and finishing,CMF)to realize the CMF-driven Miao embroidery derivative product auxiliary design and build a CMF-driven Miao embroidery derivative product configuration recommendation system.Then assist the designer to efficiently complete the preliminary design of Miao embroidery derivative products.Therefore,this paper mainly carries out the following research work:(1)In view of the importance of CMF-driven auxiliary design of Miao Embroidery derivative products in this paper,relevant theories and methods are studied.By seeking the design optimization method of the influence of user image demand cognition on product auxiliary design,the auxiliary design method of Miao Embroidery derivative products is studied from the perspective of CMF,and relevant concepts and theoretical methods such as CMF design,Kansei engineering theory,color network technology,visual and tactile cognition theory are studied.It is used to obtain the correlation between users’ image cognition and CMF elements of Miao Embroidery.Thus,this paper provides theoretical support for the research on CMFdriven auxiliary design method of Miao Embroidery derivative products.At the same time,BP neural network technology is discussed to provide theoretical support for the CMF configuration recommendation system of Miao Embroidery derivative products in this study.(2)Aiming at the coupling problem between color,material and technology(CMF)design gene and the perceptual requirements of target users in the research of Miao embroidery culture,the perceptual image analysis of Miao embroidery culture is carried out by combining color network,Kansei engineering,eye movement technology,visual and tactile cognition theory,etc.Firstly,the digital resource database of ethnic patterns is used to deconstruct and define the color,material and craft elements of Miao embroidery needed in this study.Then,according to the color network and eye movement technology,the color,material and process of Miao embroidery were screened and representative samples were made,with the purpose of determining the CMF element representative samples of Miao embroidery recognized by target users.Through the visual and tactile evaluation mode,the sample perceptual image of CMF element of Miao embroidery is determined.According to the visual and tactile image cognition test of CMF element of Miao embroidery,the cognitive evaluation data of CMF element of Miao embroidery are obtained,which provides data support for the subsequent construction of CMF image prediction model of derivative products of Miao embroidery driven by BP neural network.(3)Aiming at the problem of user image demand prediction in auxiliary design of Miao Embroidery derivative products,this paper takes the CMF design elements and perceptual image evaluation values obtained in Chapter 3 as training sample data to code,and writes the Miao embroidery image scoring program and CMF element annotation program,thus completing the acquisition of the corresponding data of Miao embroidery CMF elements and users’ perceptual image.Therefore,it constructs the CMF element image prediction model of Miao Embroidery with BP neural network,and uses Kansei engineering theory to obtain users’ perceptual image cognition of different CMF elements of Miao embroidery,providing support for the research and analysis of auxiliary design.(4)In order to fully acquire user imagery and assist designers to efficiently complete the design of derivative products of Miao Embroidery,based on the above research methods,a prototype system of CMF configuration recommendation for derivative products of Miao Embroidery is built.The system includes four core functions: CMF resource library architecture design,CMF element configuration recommendation,evaluation management and resource management.By integrating CMF element design resources of Miao Embroidery,target users and designers can participate in the design process of derivative products of Miao Embroidery for effective communication.At the same time,it provides a new idea for designers to integrate the design of Miao embroidery color,material and surface technology,so as to assist designers in the design planning of Miao embroidery derivative products and improve its innovation efficiency. |
