基于BIM+GIS公路设计在三维场景下点定位方法探索

RESEARCH ON POINT POSITIONING METHOD IN 3^(D) SCENE OF HIGHWAY DESIGN BASED ON BIM+GIS

在BIM+GIS技术引入公路设计后,能解决空间任意点与公路平面路线之间位置关系的定位问题。利用计算机邻近搜索算法、R树构件方式及二、三维几何计算公式,推导出一种高效的计算方式,获得了GIS空间中任意点的新定位方式;实现了公路路线与空间任意点的相互换算关系,解决公路工程空间定位的问题,提升公路设计的应用效率。

After the introduction of BIM+GIS technology into highway design,the problem of location relationship between any point in space and highway plane route can be solved.By using KNN algorithm,R-tree component method and two and three dimensional geometric calculation formula,an efficient calculation method is derived,and a new location method of any point in GIS space is obtained.It realizes the conversion relationship between highway route and any point in space,solves the problem of spatial positioning of highway engineering,and improves the application efficiency of highway design.
