基于坐标映射模型的方向关系一致性检验
Consistency Check for Direction Relations Based on Coordinate Mapping Model
摘要
Abstract
In order to deal with the complex direction of the three-dimensional objects, the coordinate mapping model for cardinal direction relations of three-dimensional objects is put forward in this paper, which bases on simple data model and uses projection method and the simplicity of interval operation. On the basis of this model, the basic reasoning operations for cardinal direction relations of three-dimensional objects and the identification of convex relations are discussed. Basing on preceding knowledge, the consistency checking arithmetic for cardinal direction relations of three-dimensional objects and the corresponding correctness proof is given.关键词
