【摘要】：保持建筑物群的空間分布模式一致是道路與建筑物空間沖突處理問(wèn)題的難點(diǎn)。按道路對(duì)建筑物的包圍程度,將道路與建筑物之間的關(guān)系類(lèi)型劃分為開(kāi)放型、半開(kāi)放型和閉合型。本文提出了基于幾何相似性的建筑物移位算法,并以距離、角度和面積作為滿足幾何相似性的約束條件。以道路網(wǎng)眼為單位,采用最小生成樹(shù)的方法生成建筑物群的骨架,以骨架的長(zhǎng)度和角度特征分別作為建筑物移位的距離和角度約束條件,以建筑物與網(wǎng)眼的面積比作為建筑物移位的面積約束條件。針對(duì)可能出現(xiàn)的次生沖突,探討了次生沖突的處理方法。試驗(yàn)結(jié)果表明,本文方法能夠消除因道路拓寬導(dǎo)致的道路與建筑物沖突,并能完備地保持建筑物群的空間分布模式。
[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.
