摘要
针对传统地籍调查方法在人员投入、成本需求和作业效率等方面的痛点和不足,该文以新疆图木舒克市地籍调查项目为例,根据项目任务区的地籍要素特点,将无人机倾斜摄影测量、超站仪无控制点模式支持下的1∶500比例尺解析法测量、三维激光扫描和基于EPS平台的三维测图等多技术交叉融合运用,并结合优化后的权属调查模式构建出一套适用于面积范围大、房屋较分散的农村国有土地权籍调查方法,同时对无人机倾斜摄影测量技术获取的三维模型精度和多技术交叉融合获得的最终地籍成果精度进行了验证。结果表明:无人机倾斜摄影测量技术获得三维模型精度满足地籍测量精度要求;多种技术交叉融合的方式不仅保证了调查成果的质量,而且有效提高了工作效率;优化后的外业调查方法不仅省时省力,而且调查结果具有公信力。实践证明本文提出的多种技术交叉融合方法值得在开展地籍调查相关工作中推广应用。
Aiming at the pain points and deficiencies of traditional cadastral survey methods in personnel investment,cost demand and operation efficiency,the paper takes the cadastral survey project in Tumushuke City,Xinjiang as an example,according to the characteristics of cadastral elements in the task area of the project,the multi technologies such as UAV oblique photogrammetry,the 1∶500 scale analytical survey methods supported by super station with no control point measurement mode,three-dimensional laser scanning and three-dimensional mapping based on EPS platform are integrated.Combined with the optimized ownership survey mode,a set of rural state-owned land ownership survey method suitable for large area and scattered rural houses was built.Finally,the accuracy of 3 D model obtained by UAV oblique photogrammetry technology and the final cadastral accuracy obtained by multi technology cross fusion are verified.The results showed that:the accuracy of 3 D model obtained by UAV tilt photogrammetry meet the accuracy requirements of cadastral survey;the multi technology integration not only effectively ensures the quality of the survey results,but also improves the work efficiency significantly;the optimized survey method not only saves time and effort,but also has credibility.It is meaningful using multi technology cross fusion method in the promotion and application of cadastral survey related work.
