【摘要】:保持建筑物群的空间分布模式一致是道路与建筑物空间冲突处理问题的难点。按道路对建筑物的包围程度,将道路与建筑物之间的关系类型划分为开放型、半开放型和闭合型。本文提出了基于几何相似性的建筑物移位算法,并以距离、角度和面积作为满足几何相似性的约束条件。以道路网眼为单位,采用最小生成树的方法生成建筑物群的骨架,以骨架的长度和角度特征分别作为建筑物移位的距离和角度约束条件,以建筑物与网眼的面积比作为建筑物移位的面积约束条件。针对可能出现的次生冲突,探讨了次生冲突的处理方法。试验结果表明,本文方法能够消除因道路拓宽导致的道路与建筑物冲突,并能完备地保持建筑物群的空间分布模式。
[Abstract]:Keeping the spatial distribution pattern of building group consistent is a difficult problem in dealing with the spatial conflict between road and building. According to the degree of road-to-building encirclement, the relationship between road and building is divided into three types: open type, semi-open type and closed type. In this paper, a building displacement algorithm based on geometric similarity is proposed, and distance, angle and area are taken as constraint conditions to satisfy geometric similarity. Taking the road mesh as the unit, the minimum spanning tree is used to generate the skeleton of the building group, and the length and angle characteristics of the skeleton are used as the distance and angle constraints of the displacement of the building, respectively. The area ratio of the building to the mesh is taken as the area constraint condition of the displacement of the building. Aiming at the possible secondary conflict, the methods of dealing with the secondary conflict are discussed. The experimental results show that the proposed method can eliminate the conflict between road and building caused by road widening, and can completely maintain the spatial distribution pattern of building group.
