Computer vision is concerned with automatic extraction of useful information from images. Spatial modeling is one of the most important parts in the area of spatial relations, and it is necessary to develop a new model with high practicality. Firstly this paper analyzes the characteristics and defects of present models; secondly introduces in detail the construction method of quad-tree histogram; thirdly cloud model are used to judge spatial directional relation. The experimental results show that the model is feasible.
