无人机摄影测量像片倾角对成图精度的影响分析

Analysis of Influences of Tilt Angle of UAV Photogrammetry on Mapping Accuracy

目前无人机进行测图已逐渐在工程中得到应用,对于无人机测绘中的精度一直是测绘领域讨论的重要议题,从无人机拍摄过程中像片倾角产出的原理出发,分析倾角与测量地物精度的关系,并通过实例进行验证,在此基础上提出避免倾角过大的处理方法。

With frequent application of UAV surveying and mapping in engineering, its surveying accuracy has become an important topic in the field. Starting from the causes of tilt angle of UAV photogrammetry, the correlativity between tilt angle and surveying accuracy of ground objects has been analyzed and verified by examples to put forward methods to avoid excessive tilt angle.
