7个令人敬畏的UAS调查
Nowadays, it’s hard to imagine the geomatics industry without unmanned aerial vehicles (UAVs) – and yet they only arrived on the scene around five years ago. When the very first versions of the small commercial drones were unveiled at trade fairs like Intergeo, they were dismissed by some as a hype. Nothing could have been further from the truth! Today, unmanned aerial systems have firmly established themselves as valuable tools in the data collection process. In fact, they are already achieving impressive results! We put together an overview of seven awe-inspiring UAV surveys as an example of just what they are capable of.
基督救赎主雕像，里约热内卢
里约热内卢的著名基督雕像已使用无人机在3D中重建。挑战天气条件和纪念碑的巨大规模意味着需要仔细的计划来完成项目并保持安全性。在雕像周围捕获了数千张图片，并进行了加工，以创建一个庞大而准确的点云和纹理的网眼。救赎主基督在3D中重建
采矿业，安达卢西亚，西班牙
越来越多的矿业公司正在使用无人机（UAV）。188asia备用网址这种遥控小型飞机配备了数码相机，可生成高分辨率的航空影像，可以进一步处理以产生高度精确的正射原位，点云和3D模型。测量师和工程师可以使用这些数据来制作有关矿山开发的陈述和预测，文件更改以及计算宠物和库存的数量。在具有地上和地下区域的地雷中，无人机可以提供有关地上区域状态的重要信息，从而提高了地下工人的安全。这是在西班牙安达卢西亚的Mina deaguasteñidas的80公顷土地上进行的。Unmanned Aerial Vehicles in the Mining Industry
Easter Island, Chile
无人空中系统（UASS）可以轻松运输，并且此有益的功能是对远程空间进行摄影测量的理想选择。拉帕·努（Rapa Nui）是地球上最孤立的居住地，由于云层覆盖，大风天气和岛屿的巨大规模，UAS的摄影测量法达到了极限。由此产生的矫形器和数字表面模型将支持考古文档和研究。考古特征将在一个详细的数据库中存档。作者讨论了这一令人兴奋且具有挑战性的冒险。UAS对复活节岛的调查
Chuquicamata Mine, Andes, Chile
在采矿中，确定音量随时间变化是一项重要的测量任务。但是，恶劣的环境可以使聚集精确，最新的地理达塔具有挑战性。传统的土地测量和陆地激光扫描在远程开放坑矿中使用时面临许多障碍。UAS提供了一种替代方案，而不会损害准确性。在这里，作者提出的UAS调查在安第斯山脉进行了高度进行。在安第斯山
Prague Castle, Czech Republic
In a recent project to obtain detailed and accurate orthoimages and 3D models to support technical staff in maintaining Prague Castle in the Czech Republic, the site was captured by UAS photogrammetry. Videos and georeferenced panoramic images were also taken as a service to documentalists and to provide the basis for virtual tours for tourists. Prague Castle and its surroundings are heavily secured sites and special permission was required to conduct the air survey.Modelling Prague Castle with a UAS
贝宁
在赤道附近的国家进行调查时，环境条件可能很恶劣。热，灰尘和湿度可能会破坏敏感的设备，而不信任的当地人可能会阻碍这项工作。继续阅读以了解在西非贝宁萨凡纳的UAS调查中的经验。UAS Experiences in Africa: Heat, Dust and Distrustful Locals
Salar de Coposa, Chile
Edáfica, a Chilean environmental consulting company which owns an sUAS Stardust II, was hired by Collahuasi mining company to conduct a survey of biophysics and ecotypes. The aim of the survey was to explain the conservation status of the species Frankenia triandra growing in Salar de Coposa under governmental protection.UAS在海拔4300m处进行调查
