倾斜实景模型和LiDAR点云数据相融合的不动产测量新方法

不动产地籍测量是一项基础性的测绘工作，地籍测量技术与方法的良性发展不仅能够最大限度地提升我国土地利用率，还能为获取高精度的空间数据提供高效便捷的手段。针对传统全站仪与GPS RTK组合地籍测量作业效率低、人力财力耗费大的缺点，本文依托陕南某地的地籍和不动产权籍调查项目，提出了一种地面三维激光扫描技术和倾斜摄影测量技术相结合的混合作业新方案。两种技术的融合大大提高了工作效率及数据采集精度，数据获取速度是传统作业速度4倍以上，界址点误差小于3 cm，满足对复杂空间权利的不动产权籍管理和登记需求。

A new real estate measurement method based on fusion of oblique photogrammetric real scene model data and LiDAR point cloud data

Real estate cadastral surveying is a basic surveying and mapping work.The development of cadastral surveying techniques and methods can not only maximize the utilization rate of land in China,but also provide an efficient and convenient means for obtaining high-precision spatial data.The traditional total station and GPS RTK combined cadastral survey has the disadvantages of low efficiency and labor and financial expenditure.Based on the cadastral and immovable property survey project in the core area of the Hengkou demonstration area(test area),this paper proposes a combination of ground three-dimensional laser new scheme of mixed operation of scanning technology and tilt photogrammetry technology.The integration of the two technologies greatly improves work efficiency and data collection accuracy to meet the needs of real estate management and registration of complex space rights.Data acquisition speed is more than 4 times the traditional operation speed,Boundary point error is less than 3 cm.
