The construction industry lacks solutions for accurately, comprehensively and efficiently tracking the three dimensional (3D) status of buildings under construction. Such information is however critical to the successful management of construction projects: it supports fundamental activities such as progress tracking and construction dimensional quality(More)
This paper presents a system to manipulate 3D objects or navigate through 3D models by detecting the gestures and the movements of the hands of a user in front of a camera mounted on top of a screen. This paper more particularly introduces an improved skin color segmentation algorithm which combines an online and an offline model; and a Haarlet-based hand(More)
In a reversal of historic trends, the capital facilities industry is expressing an increasing desire for automation of equipment and construction processes. Simultaneously, the industry has become conscious that higher levels of interoperability are a key towards higher productivity and safer projects. In complex, dynamic, and rapidly changing(More)
This paper presents a new approach that allows automated recognition of three-dimensional (3D) Computer-Aided Design (CAD) objects from 3D site laser scans. This approach provides a robust and efficient means to recognize objects in a scene by integrating planning technologies, such as multi-dimensional CAD modeling, and field technologies, such as 3D laser(More)
One of the main criticisms of the construction industry is that projects are too often completed behind schedule (and/or with cost overruns). Schedule delays may result from poor planning, but also from poor progress control, because, if progress deviation is identified too late, then actions can often not be taken to avoid the impact of these delays on the(More)
