摘要
传统大比例尺地籍测量存在外业工作量大,工期较长,成本高等问题。随着现代化测绘技术的不断发展,出现了无人机倾斜摄影技术。该技术有着高效率、低成本、操作简单灵活、获取数据精确等诸多优势。文章基于无人机倾斜摄影技术,研究该技术在大比例尺地籍测量中的应用,并以浙江省桐乡市秋韵小区为例做了精度验证。结果表明,利用无人机倾斜摄影技术进行大比例尺地籍测量,能大大减少外业工作量,缩短工期,降低成本,精度可达到厘米级,并且符合国家地籍测量精度要求。无人机倾斜摄影测量技术弥补了传统地籍测量方式的缺点和局限性,有着广阔的实际应用和推广前景。
The traditional large-scale cadastral survey has many problems,such as heavy workload,long construction period and high cost.With the continuous development of modern surveying and mapping technology,UAV tilt photography technology has emerged.This technology has many advantages,such as high efficiency,low cost,simple and flexible operation,accurate data acquisition and so on.Based on UAV tilt technology,this paper studies the application of this technology in large-scale cadastral survey,and takes Qiuyun District of Tongxiang City,Zhejiang Province as an example to verify the accuracy.The results show that the large-scale cadastral survey using UAV tilt photography technology can greatly reduce the field work,shorten the construction period,reduce the cost,and the accuracy can reach centimeter level,and meet the national cadastral survey accuracy requirements.UAV tilt photogrammetry technology makes up for the shortcomings and limitations of traditional cadastral survey methods,and has a broad prospect of practical application and promotion.
