摘要
数字正射影像具有精度高,地物信息丰富等特点,目前广泛应用于城市规划、生态监测、地理普查等领域。本文针对大高差地形下数字正射影像的生产,利用飞马D2000S无人机分别使用定高与变高两种航高设计方案进行航飞,并对两种方案的成果进行分析与比对,探讨了不同航高对于数字正射影像质量与精度的影响,为复杂地形条件下的航线设计提供了参考思路。
Digital orthographic maps are widely used in urban planning,ecological monitoring,geographical census and other fields due to their high accuracy and abundant feature information.For digital orthophotos production in terrain with large altitude difference,fixed and variable altitudes were used for flying with the Feima D2000S UAV.The results of the two schemes are analyzed and compared to explore the impact of different altitudes on the quality and accuracy of digital orthophotos,which can provide a reference idea for route design in complicated terrain situations.
