| Abstract: | Based on the conecptions of visible point,visible chain and visible field,this paper analyses two factors,diameter of convex hull of two objects and their visible field,which affect direction judgement between two objects.This paper proves that it is feasible to describe directional relationships using voronoi diagram. |

| Keywords: | objects direction relationships spatial relationships voronoi diagram |
