Method for Virtual Scene Automatic Exploration
This paper presents a new method for automatic exploration in a virtual scene.First,we give a viewpoint measuring metric,which is based on fuzzy theory.Then,we use fuzzy comprehensive evaluation to calculate a fuzzy set which corresponds to a virtual viewpoint.The quality of the virtual viewpoint can be taken as an objective function and the optimal viewpoint set can be obtained by ant colony optimization algorithm.Finally,we sort the viewpoints in the optimal viewpoint set and connect them using cardinal spline curve.Consequently,the automatic exploration path is constructed.Experimental results show that our method can obtain a good exploration path which can help observer understand the scene roundly and quickly.
