dc.description.abstract | Structure from motion (SfM) is a well-known algorithm used for the generating of three-dimensional (3D) spatial information using images. The objective of this study is to compare the measurements of objects ascertained from point cloud and mesh models derived from the SfM algorithm. In particular, we analyze a single tree to determine the correlation between the number of acquired images from the UAVs and the object measurement for each model. The results indicate that the number of images does not have a critical impact on surveys and the point cloud is approximately 2% more accurate than mesh models for individual tree measurement. Our results will be useful in terms of selecting the data acquisition method as well as the data itself for measuring objects based on SfM 3D data. (C) 2019 Elsevier Ltd. All rights reserved. | - |
