在过去的几年里，无人机（UAV）的摄影测量采集得到了广泛的发展。这种移动的平台及其处理软件已经成熟，从而形成了一个向测量公司和地理空间企业提供现成测绘解决方案的市场。平台类型和光学仪器存在不同的方法，尽管其最终产品具有相似的规格。为了证明采购实践中的差异，一个案例研究在一个露天矿的飞行与两个不同的现成的无人机（固定翼和多旋翼）。分析产生的图像，以澄清收集质量的差异。我们看看图像设置，并强调如果手动设置应用的摄影经验的事实。对于地图制作，将相机设置为自动可能是最安全的。此外，我们试图估计模糊是否存在由于图像运动。一个微妙的趋势似乎是目前，为快速飞行的平台，虽然其程度是类似的顺序缓慢移动的。这表明两个系统都在其极限上运行。最后，评估透镜畸变，特别注意色差。在这里，我们看到，通过校准，这种像差可能存在，但是直接在图像上检测这种现象并不简单。对于这样的效果，普通的透镜就足够了，尽管更好的透镜和准直器确实能提供显著的改善。
Photogrammetric acquisition with unmanned aerial vehicles (UAV) has grown extensively over the last couple of years. Such mobile platforms and their processing software have matured, resulting in a market which offers off-the-shelf mapping solutions to surveying companies and geospatial enterprises. Different approaches in platform type and optical instruments exist, though its resulting products have similar specifications. To demonstrate differences in acquisitioning practice, a case study over an open mine was flown with two different off-the-shelf UAVs (a fixed-wing and a multi-rotor). The resulting imagery is analyzed to clarify the differences in collection quality. We look at image settings, and stress the fact of photographic experience if manual setting are applied. For mapping production it might be safest to set the camera on automatic. Furthermore, we try to estimate if blur is present due to image motion. A subtle trend seems to be present, for the fast flying platform though its extent is of similar order to the slow moving one. It shows both systems operate at their limits. Finally, the lens distortion is assessed with special attention to chromatic aberration. Here we see that through calibration such aberrations could be present, however detecting this phenomena directly on imagery is not straightforward. For such effects a normal lens is sufficient, though a better lens and collimator does give significant improvement.
