This paper studies the direction relations between two spatial objects and presents the reasoning model of spatial direction relation based on Voronoi diagram. The algorithm of the reasoning is described detailedly and an example is analyzed. This paper also discusses the six typical circumstances about spatial direction relation based on Voronoi diagram. These include the direction relations of point-point, point-line, point-region, line-line, line-region and region-region. At last, the advantages and disadvantages about the model are summarized.
