Unmanned aerial systems for photogrammetry and remote sensing: A review

回顾无人航空系统在摄影测量与遥感领域的发展历程。文章认为，低成本的现成设备结合计算机视觉、机器人学和地理信息技术，即使使用价格仅几百欧元的相机，也能达到厘米级的分辨率和精度。在历史和法规之后，文章介绍了平台、传感器、导航、定向和处理方面的进展，重点关注纳米级、微型和小型无人航空系统。

主要发现

• Centimetre-level resolution and accuracy achievable with consumer cameras costing a few hundred euros
• Rapid methodological change in the five years before 2014 was outpacing aviation rules and traditional workflows

局限

• Abstract only reviewed (publisher page blocked to the fetch tool)
• General mapping review, not inspection-specific
• Hardware and regulatory picture is from 2014
