摘要
传统方向关系模型难以支持空间的点、线、面物体的表示,其推理采用效率较低的查表运算,不支持复杂方向关系推理。为解决此问题,提出基于矩阵模型的方向关系表示与推理的方法。该方法为空间方向关系的定性表示、描述、推理运算构建基础理论,为空间查询和一致性校验研究提供了新思路。
Traditional direction relational model based on the table look-up operation fails to support the whole spatial object (points ,lines ,surfaces) and it is inefficient and difficult to support the complex direction relation reasoning .Direction relation based on matrix model provided a solution to solve these problems .This method constituted the basic theory for description , operator and reasoning of qualitative space relation and provided new ideas on space queries and consistency checks .
