Flight optimization algorithms for aerial LiDAR capture for urban infrastructure model generation

Hinks, Tommy ; Carr, Hamish ; Laefer, Debra F. (American Society of Civil Engineering (ASCE), 2009-11)

Aerial Light Detection and Ranging (LiDAR) offers the potential to auto-generate detailed, three-dimensional (3D) models of the built environment in urban settings. Auto-generation is needed as manual generation is not ...
Hybrid Bayesian fusion of range-based and sourceless location estimates under varying observability

Yadav, Nagesh ; Bleakley, Chris (IEEE, 2012-09-06)

The paper proposes a hybrid Bayesian approach for multi-sensor data fusion for 3D localization. The approach addresses the problem of fusing range-based and sourceless localization estimates under conditions of varying ...
Opportunities and impediments to the use of 3D laser scanning for adjacent excavations

Laefer, Debra F. ; Carr, Hamish ; Morrish, Sean ; Kalkan, Erol (American Society of Civil Engineering (ASCE), 2006-02)

Although three-dimensional laser (3DLS) scanning has been used to document and monitor individual excavation walls and structures on a limited basis, impediments remain to its use for major infrastructure projects. This ...
Storage, manipulation, and visualization of LiDAR data

Schön, Bianca ; Bertolotto, Michela ; Laefer, Debra F. ; Morrish, Sean (International Society of Photogrammetry and Remote Sensing, 2009-02)

In recent years, three-dimensional (3D) data has become increasingly available, in part as a result of significant technological progresses in Light Detection and Ranging (LiDAR). LiDAR provides longitude and latitude ...
Three-dimensional spatial information systems : state of the art review

Schön, Bianca ; Laefer, Debra F. ; Bertolotto, Michela ; Morrish, Sean (Bentham Science Publishers, 2009)

A spatial information system (SIS) is critical to the hosting, querying, and analyzing of spatial data sets. The increasing availability of three-dimensional (3D) data (e.g. from aerial and terrestrial laser scanning) and ...
Using grammatical evolution to parameterise interactive 3D image generation

Nicolau, Miguel ; Costelloe, Dan (Springer, 2011-04-27)

This paper describes an Interactive Evolutionary system for generating pleasing 3D images using a combination of Grammatical Evolution and Jenn3d, a freely available visualiser of Cayley graphs of finite Coxeter groups. ...
