摘要

Abstract > The investigation of form and processes in geomorphology and ecology is highly dependent on topographic data: a reliable digital terrain representation is in fact a key issue across environmental and earth sciences. In many cases, the processing of high‐resolution topographic data (e.g., light detection and ranging (LiDAR), structure from motion) has to face issues such as void filling, vegetation/feature removal and interpolation accuracy that are usually related to (i) intrinsic limitations of the adopted technology, (ii) local conditions affecting the survey or (iii) specific design scenario. In this paper, we develop a methodology to test the accuracy of an image inpainting algorithm to fill data voids in complex mountain areas. The devised experiment exploits the availability of a high‐resolution, LiDAR‐derived digital terrain model and the inpainting approach accuracy is checked against some widely used interpolation techniques (natural neighbor, spline, inverse distance weighting, kriging). In order to better mimic the actual surface texture, a methodology to introduce local topographic variability to the interpolated surface is also presented. The results show a better performance of the inpainting algorithm especially in the case of complex and rugged topography. Two examples showing an effective usage and accuracy of the proposed technique are reported, highlighting the drawbacks that a poor surface representation can introduce. The whole procedure is made freely available within a Matlab ? script with the addition of sample files. ?2019 John Wiley & Sons, Ltd. ?2020 John Wiley & Sons, Ltd. </abstract> </span> <span class="z_kbtn z_kbtnclass hoverxs" style="display: none;">展开▼</span> </div> <div class="translation abstracttxt"> <span class="zhankaihshouqi fivelineshidden" id="abstract"> <span>机译：</span><Abstract Type =“Main”XML：Lang =“EN”XML：ID =“ESP4739-ABS-ABS-0001”> <标题类型=“main”>抽象</ title> > 地貌和生态学的形式和过程的调查高度依赖于地形数据：可靠的数字地形表示实际上是环境和地球科学的关键问题。在许多情况下，高分辨率地形数据的处理（例如，光检测和测距（LIDAR），来自运动的结构）必须面对通常与（i ）采用技术的内在限制，（ii）影响调查或（iii）具体设计方案的当地条件。在本文中，我们开发了一种方法来测试图像修复算法的准确性，以填补复杂山区中的数据空隙。设计的实验利用高分辨率的可用性，激光雷达推导的数字地形模型，并针对一些广泛使用的插值技术（自然邻居，花键，逆距离加权，Kriging）进行检查。为了更好地模仿实际表面纹理，还呈现了向内插表面引入局部地形变化的方法。结果表明，尤其是在复杂和坚固的地形的情况下更好地性能。报告了两个示例，示出了所提出的技术的有效使用和准确性，突出了表面表示可以引入的缺点。整个过程在Matlab中自由提供？</ sup> 脚本添加样本文件。？2019年John Wiley＆amp;
