中文摘要: 智能选线是当前公路选线理论与方法的研究方向之一。经多年发展,公路智能选线取得了可喜成绩,但由于没能实现选线领域与方法知识的统一建模、知识与数值方法的联合、虚拟三维地理环境中的人机协同设计,智能选线离生产实践还有一定距离。而解决这些问题的一个关键点是如何让计算机有效识别和利用三维地理信息。因此项目提出研究三维空间信息的语义建模及语义信息的应用关键技术。首先基于本体论建立公路选线的三维空间实体概念体系,建立地理信息语义模型,并通过实例化建立地理信息数据库;然后通过联合地形因子分析、地理统计分析、三维空间分析的方法,研究长距离、大范围内路线方案走向控制信息的自动提取;再通过"提案-验证-改进"的方式,实现模拟人工作业方式的路线初始方案自动生成和局部路线方案自动设计;最后通过建立实际案例,验证、改进所提方法。课题开展能完善公路选线的理论与方法体系,为下一代道路勘测设计软件的开发奠定基础。

英文摘要: Intelligent route selection is one of the research fields of the highway route selection theories and methods. Although, after years of development, intelligent highway route selection has achieved encouraging results. Because failed to model route selection domain and method knowledge uniformly, integrate numerical and Knowledge-based methods and design route scheme man-machine corporately under virtual three dimensional circumstances, it is still not the time to put intelligent route selection into practice. The key tackling those problems is how to make computers cognize and utilize 3D geographic information automatically. So the project is proposed to study modeling of 3D spatial semantic information and key applying technology of it. Firstly, based on ontology, conceptualisation of 3D Space entities for highway route selection is established, which compose semantic model of geographic information. And by instantiation the model, GIS database can be constructed. Secondly, by unifying topographical analysis, geostatistical analysis and 3D spatial analysis method, control information for highway scheme of long distance and large range is proposed. Then, through the approach of "Propose-verify-improve", the automatic method of generating highway initial alignment and designing local alignment scheme can be put
