Embodiment

[0066] 1. Cognitive analysis of product form

[0067] According to the theory of morphology, the product can be decomposed into several basic parts, and a single basic part is analyzed and summarized, and a number of different shape element candidates can be obtained. Invite experienced designers to conduct morphological analysis experiments, and summarize the basic components of the product and the appearance unit elements of each component based on the preliminary product samples.

[0068] 2. Acquisition and analysis of multi-dimensional images

[0069] The perceptual image of a product refers to the intuitive association of the product form to the user's sensory stimulation, which reflects the user's emotional needs and the inner judgment standard of the product, and is generally described by adjectives. Take a 3D printer as an example, collect 90 typical image adjectives through the Internet, magazines, surveys, interviews, etc., select random product samples, and conduct a ques...

Abstract

The invention discloses a multidimensional image-based product design scheme evaluation method. The method includes the following steps that: (1) a k-mean clustering analysis method and factor analysis method are utilized to obtain a typical sample and typical perceptual image which accord with the perceptual cognition of a user, and then, a user-image initial evaluation value is obtained through using a semantic differential method; and (2) a gray correlation analysis and technique for order preference by similarity to an ideal solution (TOPSIS)-combined method is used to realize order optimization of alternative design schemes under the specific requirements of the multidimensional image of the user, and this process includes determining an alternative design scheme set, generating an original evaluation matrix, calculating the weights of evaluation indexes through using information entropies, constructing a normalized evaluation matrix, calculating distances, calculating relative proximities and sequencing the schemes. With the method of the invention adopted, the subjectivity of the perceptual image acquisition of the user can be balanced, and the validity of data can be ensured.

Description

Technical field [0001] The invention belongs to the technical field of product design, and specifically relates to a product design scheme evaluation method oriented to multi-dimensional images. Background technique [0002] In today's society, with the development of manufacturing and information industries, people pay more attention to their own emotional needs than ever. The emotional experience of a product has gradually become an important factor for judging the success of a product, and the development of a product that conforms to the user's perceptual image perception has become a research focus in product design. [0003] Perceptual image is a highly cohesive psychological feeling and emotional activity produced by people in the process of experiencing a product. It is currently used as an important new way of thinking about product image design. In reality, users’ image cognition is very complicated. When facing a product, users tend to use multiple image dimensions to d...
