Abstract:

Artificial fish for computer animation is created with artificial life. In order to enrich perceptive abilities of artificial fish and exhibit vivid animation, a kind of virtual smelling perception system of artificial fish is proposed based on analysis of the olfaction mechanism of natural fish and perception system of “robot fish”. Firstly, the smelling perception model in Intelligent Virtual Environment (IVE) is built. Secondly, three-layer recognition model of smelling perception is designed according to the biologic mechanism of olfaction. The recognition of smelling information is achieved using fuzzy recognition method based on principal components analysis. The result is satisfied in computer animation simulation. And the design of smelling perception system will set a good foundation for research on multi-perception fusion and supplies a software simulation platform for the researching on recognition of smelling of robot fish.
