Comparing Aerial Photogrammetry and 3D Laser Scanning

3dTexturemodel

In the last decade, the evolution in computing power – both in CPUs and GPUs – has allowed the development of photogrammetry software that can turn a set of photos of an object, such as a building, into a 3D model. These software products compete with laser scanners, which are widely used throughout design, construction, and operations of infrastructure assets due to their fast acquisition time and remarkable accuracy.

In this paper, entitled “Comparing Aerial Photogrammetry and 3D Laser Scanning Methods for Creating 3D Models of Complex Objects,” we assess the accuracy of photogrammetry reconstruction by comparing outcomes when capturing and processing various scenes using ContextCapture software [4] and laser scanner-generated point clouds.
