倾斜摄影测量在港口中的应用及精度分析

针对如何在大范围水域覆盖地区(尤其包括如防波堤或LNG码头等三面环水的条带状区域)生成高精细程度、高位置精度的实景三维模型,采用倾斜摄影测量技术并以港口的具体工程为例进行研究,系统梳理该技术的应用流程,并对生成的实景三维模型进行精度统计,取得了平面精度及高程精度均优于2个像元大小的高精度效果.验证了该技术流程应用于港口...

Application and accuracy analysis of oblique photogrammetry in port

This paper studies how to generate the real 3D model with high degree of fineness and high positional accuracy in areas covered by a wide range of waters(especially including strip-shaped features which surrounded by water on three sides such as breakwaters or LNG mole),which takes the application of oblique photogrammetry technology in port engineering as an example,systematically summarizes the technological process of the application of this technology,and calculates the accuracy of the real 3D model which created from the process,which shows the high-accuracy effect that the accuracy of flat surface and elevation are better than two pixel size.This paper verifies the feasibility of the technical process and the reliability of the accuracy of the generated real 3D model,which can provide reference for similar projects.
