基于DSM坡度分析的建筑变化监测研究

Study on Monitoring of Buildings Change Based on DSM Slope Analysis

针对传统的监测手段存在的数据源精度不够、监测方法不科学、监测结果不准确等问题,创新性地提出了基于DSM(digital surface model)坡度分析的建筑自动变化监测技术体系,通过对多期高分辨率的DOM(digital orthophoto map)及DSM数据进行差值计算、坡度分析、阈值筛选等处理,最终得到研究区的建筑变化图斑。研究表明,该方法可广泛应用在建筑变化监测领域。

Aiming at the problems of inadequate accuracy of data sources,unscientific monitoring methods and inaccurate monitoring results in traditional monitoring methods,this paper puts forward an innovative technology system to automaticlly monitoring house changes based on DSM slope analysis.,The variation patterns of the housing buildings in the study area are finally obtained by processing the multi-period high resolution DSM and DOM data through difference calculation,slope analysis,threshold screening and so on.Research shows that it can be widely used in the field of housing change monitoring.
