仿地飞行与定高飞行创建三维模型的差异分析

Difference Analysis of 3D Model Creation between Imitating Ground Flight and Fixed Altitude Flight

社会经济的发展和生产力的提高离不开科学技术的提升及合理的利用,其中,无人机的低空摄影测量技术慢慢走进各个领域。低空无人机性能优越,操作简易,智能化较高,安全机制健全,高效低成本等优点成为了工程项目勘测设计的首选方式。基于无人机倾斜摄影技术的三维建模具有高效率、高分辨率、低成本、低风险的特点,成为了三维地理信息新时代的重要元素。文章旨在介绍基于倾斜摄影采用不同的飞行作业方式采集数据,以及将数据处理后得到的三维模型进行对比分析。

The development of social economy and the improvement of productivity cannot be separated from the promotion of science and technology and the reasonable utilization,among which,the low-altitude photogrammetry technology of UAV has gradually approached various fields.The low altitude UAV has become the preferred method for engineering survey and design because of its superior performance,easy operation characteristic,high intelligence,sound safety mechanism,high efficiency and low cost.The 3D modeling based on UAV tilt photography has the characteristics of high efficiency,high resolution,low cost and low risk.It has become an important element in the new era of 3D geographic information.The purpose of this paper is to introduce different flight operation methods to collect data based on oblique photography.The data processing of the 3D dimensional model is compared and analyzed.
