This paper stems from the research of innovation-oriented compuLor-aided conceptual product design technology, which is one case of the National High Technology Research and Development Program of China(863A).On the basis of application of machinery and power-generating product design, this paper analyzes and quantifies the theory of equilibrium and stability via analyzing the pictures of product, which is one of aesthetics standard method in design process. Therefore, the theory of visual gravity and its calculating model are advanced. With applying the technology of detecting edges and gray histogram, the required image information cire picked up. At last, two kind of ari thmetic are proposed according with the visual tension theory and the moment balance principle. Then, this paper establishes the prototype of visual gravity calculation, and realizes it on the Solidworks platform. |
