Using controlled shooting distances and angles, different images sets were captured and processed with a structure from motion based technique, which can reconstruct 3D models based on multi-view, two-dimensional (2D) images. Those 2D geometries are shown to generate significant deformations within the resulting point cloud, especially where there were large angles (with respect the camera position and the wall's normal direction) and at close distances to the wall's surface. This paper demonstrates that by overlapping different flawed image sets, the deformation problem can be minimised.||Funding Details:||European Commission Horizon 2020||Type of material:||Conference Publication||Publisher:||CRC Press||Keywords:||3D reconstruction;Unmanned aerial vehicle (UAV);Structure from motion (SFM);Aerial inspection;Camera angle;Camera distance||DOI:||10.1201/9781315210469-350||Language:||en||Status of Item:||Peer reviewed||Is part of:||Cepin, M., Bris, R.
