The addition of drones to the archaeologist's toolbox has brought about exciting new possibilities, particularly for field research and the conservation and protection of our built heritage. As drones become more widely available and effective, the challenge of precision becomes more important. Better georeferencing and higher-resolution outputs are the current thresholds. In order to achieve the second objective with our current equipment, drones have to fly closer to the ground and, ideally, follow the elevation of the surface. This task can be extremely complicated along the steep surfaces and mountains typical to the Andean region where we work. In this article, we present a recording (flying and photographing) methodology that achieves a higher ground resolution by dividing up the sites into several altitudinal sections, which are flown independently yet processed photogrammetrically as a single set. We have named this methodology “Flying Slopes in Multiple Stepped Polygons.”

用无人机记录山坡上的考古遗址

将无人机添加到考古学家的工具箱中带来了令人兴奋的新可能性，特别是在实地研究以及保护和保护我们的建筑遗产方面。随着无人机变得越来越广泛和有效，精度的挑战变得更加重要。更好的地理参考和更高分辨率的输出是当前的阈值。为了用我们现有的设备实现第二个目标，无人机必须飞得更靠近地面，理想情况下，要跟随地面的高度。沿着我们工作的安第斯地区典型的陡峭表面和山脉，这项任务可能非常复杂。在本文中，我们提出了一种记录（飞行和拍摄）方法，该方法通过将地点划分为几个高度部分来实现更高的地面分辨率，它们是独立飞行的，但经过摄影测量作为一个单独的集合进行处理。我们将这种方法命名为“多阶梯多边形中的飞行斜坡”。
