The survey of the Basilica di Collemaggio in L’Aquila with a system of terrestrial imaging and most proven techniques [PDF]
, 2017 The proposed job concerns the evaluation of a series of surveys carried out in the context of a campaign of studies begun in 2015 with the objective of comparing the accuracies obtainable with the systems of terrestrial imaging, compared to unmanned ...

Perceptual Biases in the Interpretation of Non-Rigid Shape Transformations from Motion
VisionMost existing research on the perception of 3D shape from motion has focused on rigidly moving objects. However, many natural objects deform non-rigidly, leading to image motion with no rigid interpretation.

Suitability of ground-based SfM-MVS for monitoring glacial and periglacial processes [PDF]
, 2016 Photo-based surface reconstruction is rapidly emerging as an alternative survey technique to lidar (light detection and ranging) in many fields of geoscience fostered by the recent development of computer vision algorithms such as structure from motion ...

Application of ‘Structure from Motion’ (SfM) technique in physical hydraulic modelling
Journal of Physics: Conference Series, 2019 Abstract There are many methods available for measurement of bed morphology in physical hydraulic model studies considering mobile bed sediment. Among which, there are sophisticated instrumentations which provide quality results in shorter time but are vastly expensive and requires special training for execution. Whereas the conventional

The Visual Priming of Motion-Defined 3D Objects. [PDF]
PLoS ONE, 2015 The perception of a stimulus can be influenced by previous perceptual experience, a phenomenon known as perceptual priming. However, there has been limited investigation on perceptual priming of shape perception of three-dimensional object structures ...

ISPRS International Journal of Geo-Information, 2018 In vineyards, especially on steep slopes like the Ruwer-Mosel Valley, Germany, soil erosion is a well-known environmental problem. Unfortunately, some enterprises and farmers are not aware of how much soil is being lost and the long-term negative impacts

The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2023 Abstract. The purpose of this research study is to assess the potential using smartphone camera captured images for 3D model reconstruction by using Structure from Motion (SFM) photogrammetry technique, specifically in term of volumetric measurement. In past, the volumetric measurement of surface or object is by using Imaging Station or by professional

ENFT: Efficient Non-Consecutive Feature Tracking for Robust Structure-from-Motion
, 2016 Structure-from-motion (SfM) largely relies on feature tracking. In image sequences, if disjointed tracks caused by objects moving in and out of the field of view, occasional occlusion, or image noise, are not handled well, corresponding SfM could be ...
