基于Smart3D三维模型的大比例尺地形图测绘精度分析

近几年来,随着无人机技术的迅猛发展,无人机价格也变得相对便宜起来,倾斜摄影实景三维建模变得异常火爆,相关研究成果也是层出不穷。运用Smart3D重建三维模型,在所获得三维模型上进行大比例尺地形的测绘,相对于传统数字测图,更新了传统数字测图的作业方式、节省更多的时间、提高测图的效率、节省成本。在三维模型上进行大比例尺地形图的测绘,最重要的就是保证精度,本文就基于Smart3D重建的三维模型进行1∶500地形图精度的分析。

Accuracy Analysis of Large Scale Topographic Map Based on Smart3D 3D Model

In recent years,with the rapid development of UAV technology,the price of UAV has become relatively cheap,3D modeling of tilted photography scene has become very popular,and related research results are emerging in endlessly. Smart 3D is used to reconstruct the 3D model,and large-scale topographic mapping is carried out on the acquired 3D model. Compared with the traditional digital mapping,the traditional digital mapping method is liberated,more time is saved,mapping efficiency is improved and cost is saved. The most important thing is to ensure the accuracy of large-scale topographic mapping on the three-dimensional model. This paper analyzes the accuracy of 1 ∶500 topographic map on the three-dimensional model reconstructed by Smart 3D.
