基于空间数据融合算法的铁路用地管理系统研究与应用

Railway land management system based on spatial data fusion algorithm

  • 摘要: 为加强对铁路用地的监管和综合利用,设计铁路用地管理系统。提出了基于尺度不变特征转换的空间数据融合算法,通过关键点提取、特征点识别、关键点位置及尺度确定、方向提取及关联关系建立等步骤,将来自不同铁路局集团公司的用地图进行拼接融合,形成铁路用地数据库,实现了权属管理、资产处置及综合开发等功能,为实现全国铁路用地数据联动、统筹规划、统一管理的目标起到了积极推动作用。

     

    Abstract: This paper designed a railway land management system to strengthen the supervision and comprehensive utilization of railway land, and proposed a spatial data fusion algorithm based on scale invariant feature transformation. Through the steps of keypoint extraction, feature point recognition, keypoint position and scale determination, direction extraction, and association relationship establishment, the paper concatenated and fused the maps from different railway group companies to form a railway land database, which implemented functions such as ownership management, asset disposal, and comprehensive development. It plays a positive role in promoting the goal of national railway land data linkage, overall planning, and unified management.
