上海市网格化管理部件变化匹配与更新探究

Research on the Change Matching and Update of Grid Management Components in Shanghai City

为满足上海市网格化管理部件数据的生产和更新需求,基于目前开展的道路全息测绘和管线探测工作,通过分析其中不同来源城市网格化管理部件的几何相似度和语义相似度,提出多源部件数据的变化匹配算法和更新方案,并选取实验区对网格化管理部件进行实测,进而验证了算法的有效性。实验结果表明,利用本文提出的变化匹配策略和更新方案,可以有效减少城市网格化管理部件的重复采集,可充分发挥测绘成果的共享价值。

To meet the production and update needs of Shanghai’s grid management component data,by analyzing the geometric similarity and the semantic similarity between road holography and pipeline detection,we proposed a change recognition algorithm and an update scheme for multi-source component data,and selected a test area to measure grid management components,which verified the effectiveness of algorithm and update scheme.The experimental results indicate that using the change matching strategy and update scheme described in this article can effectively reduce the repeated collection of urban grid management components and fully leverage the shared value of surveying and mapping results.
