A short sequence (5 sec) of underwater images in the wake of a clear water scour. The images show the bottom movements behind a pier on a single grain level. Hence, each moving grain is visible. The bed material consists of sand dm=1.x

Underwater 3D reconstruction techniques such as underwater photogrammetry are the latest trend in low cost survey techniques. Allowing for high resolution models to be fabricated using off-the-shelf digital cameras and editing software, this method in shallow water envi...

The evolution of underwater photogrammetry allows to realize 3D models of submerged object and structures throughout the use of rapid and efficient procedures either in terms of data acquisition and data processing. These procedures are based on solutions that are appli...

Modern digital cameras are increasing in quality whilst decreasing in size. In the last decade, a number of waterproof consumer digital cameras (action cameras) have become available, which often cost less than $500. A possible application of such action cameras is in t...

Volume XLII-2/W10; Underwater photogrammetry in archaeology in Egypt is a completely new experience applied for the first time on the submerged archaeological site of the lighthouse of Alexandria situated on the eastern extremity of the ancient island of Pharos at the f...

The interdisciplinary work we present here is aimed principally at administering diverse types of information collected during an archaeological excavation using a single data management system. The approach is global, from the consultation of three- dimensional data to...

The article presents an innovative methodo logy for the 3D surveying and mod eling of floating and semi-submerged objects. Photogramm etry is used for surveying both the underwater and emerged parts of the object and the two surveys are com bined together by means of sp...

Hydraulically induced scour of the streambed at the base of bridge piers is the leading cause of bridge failures. Despite the significant scientific efforts towards the solution of this challenging engineering problem, there are still no reliable tools for the predictio...

The interdisciplinary work presented here deals with the management of diverse types of information collected during an archaeological excavation, and organized as an XML based data management system. The approach is global, from the consultation of three-dimensional da...
