摘要
针对近岸区域地形探测及数据处理过程中存在数据不连续、精度及垂直基准难以统一等问题,本文提出一种融合航空遥感、机载LiDAR、GNSS-RTK,及水上水下一体化测量等技术的空地水一体化协同测绘方法,并以北江干线三维地形测量工程为例,阐述该方法的应用过程实践,为水域地形测量在测量效率、精度与数据质量等方面的提升开拓了新的解决思路。
Aiming at the problems of discontinuity of data,difficulty in unifying accuracy and vertical reference in the process of terrain detection and data processing,this paper proposed collaborative surveying and mapping method based on air,ground and water fusion technology that integrates aerial remote sensing,airborne LiDAR,GNSS-RTK,and ashoreunderwater integrated measurement.This research took the Beijiang main channel three-dimensional topographic survey project as an example to illustrate the application process of this method,and found new solutions for the improvement of measurement efficiency,accuracy and data quality in water area topographic survey.
