A New Design Method of Mechanical and Electrical Products Appearance Modeling Based on Entity Patterns Gene

Product pattern design has gradually become the key factors of purchase, which often has profound culture, a very high aesthetic and artistic value. In order to improve mechanical and electrical product design efficiency and effect, shorten the product development cycle, improve product competitiveness, in this paper, a new design method of mechanical and electrical products appearance modeling based on entity patterns gene was put forward. Pattern elements were changed into the vector units Nusing image processing function of MATLAB software, including image segmentation, image preprocessing, contour extraction, extracting the key points, the outputting coordinate value and the non-uniformity of B spline curve fitting. Complex and beautiful products appearance could be generated with UG secondary development platform based on Visual C++6.0 by selecting the different rules of composition. Finally, the appearance modeling of an air-cleaner was designed using above these steps, which could be obtained an excellent design in high efficiency. These would promote culture, aesthetic and artistic of produces, and enhance competitiveness and purchase of produces.
