Comparing Lidar and Photogrammetric Point Clouds

Airborne Lidar and photogrammetry are both viable methods for capturing point clouds for 3D modelling of man-made hard structures. Although both methods produce point clouds, the manner of capturing data differs in many ways, resulting in point clouds with differing characteristics. In this article, the author evaluates Lidar and photogrammetric point clouds captured from unmanned airborne systems for inspecting a flood control structure. The New Orleans District of the U.S. Army Corps of Engineers (USACE) has been using small unmanned airborne... (read more)
