Recent stereo cameras provide reliable 3D reconstructions. These are useful for selecting ground-plane points, register them and building mosaics of cluttered ground planes. In this paper we propose a 2D Iterated Closest Point (ICP) registration method, based on the distance transform, combined with a fine-tuning-registration step using directly the image data. Experiments with real data show t...

In the valley of Euphrates River to south Haditha city (West Iraq), dissolution carbonate rocks which underlie residual soil gives rise numerous sinkholes. These sinkholes are a potential hazard human safety and damage existing infrastructure. The exposed in area under consideration belong Formation Early Miocene age, specifically Middle Member formation. Tens have developed with different shap...

Sinkholes are sudden disasters that usually small in size and occur at unexpected locations. They may cause serious damage to life property. Sinkhole-prone areas can be monitored using Interferometric Synthetic Aperture Radar (InSAR) time series. Defining a pattern InSAR-derived spatio-temporal deformations, this study presents sinkhole detector, called the Sinkhole Scanner. The Scanner include...

Introduction: Sinkholes are ground collapses that can cause significant damage to infrastructure and buildings. Part of the risk represented by sinkholes is related their abruptness difficulty in spotting advance exact location within a sinkhole-prone area. For this reason, urban planning informed an accurate mapping monitoring one most effective ways reduce risk. Methods: In study, we propose ...
