倾斜摄影测量技术的三维城市不动产测绘系统研究

Research on 3D Urban Real Estate Surveying and Mapping System Based on Oblique Photogrammetry Technology

为了促进城市规划建设的发展,研究采用了倾斜摄影测量技术来获取测绘区域的影像数据,并设计了三维城市不动产测绘系统。研究也进行了三维语义表达和多源数据融合。结果显示,研究所设计测绘系统的中央处理器利用率最大值和最小值分别为23.87%和21.13%,耗时最大值和最小值分别为263 ms和248 ms,冗余度最大值为0.02。该系统能够为城市规划提供数据支持。

In order to promote the development of urban planning and construction,oblique photogrammetry technology was adopted to obtain image data of the surveyed area,and a three-dimensional urban real estate surveying and mapping system was designed.The study also conducted three-dimensional semantic expression and multi-source data fusion.The results showed that the maximum and minimum utilization rates of the central processing unit of the surveying and mapping system designed by the research institute were 23.87%and 21.13%,respectively.The maximum and minimum time consumption values were 263 ms and 248 ms,respectively,and the maximum redundancy value was 0.02.This system can provide data support for urban planning.
