Three dimensional building models have become important during the past years for visualization of touristic or historic objects. Detailed facade models are essential for realistic impressions on a terrestial observer. Such models require both a geometric component that describes the shape of the building or parts of it as well as a texture component that provides color information and depicts ...

Laser data and optical data have a complementary nature to 3D features’ extraction. Building reconstruction by fusion of the two data sources can reduce the complexity of approaches from either side. In this paper we present a model refinement method, which uses the strong lines extracted from close-range images to improve building models reconstructed from terrestrial laser point clouds. First...

OBJECTIVES The study sought to identify the varied types of change arising from internal and external influences in assisted living (AL) settings, expanding upon the literature's limited focus on resident decline and staff turnover and clarifying the importance of changes to life and work there. METHOD This analysis employed qualitative interviews and observations from 4 studies involving 17 ...

These days 3d models are used in a huge variety of applications and the demands in quality and quantity are steadily growing. At the same time, the extraction of man-made objects from measurement data is quite traditional. Often, the processes are still point based, with the exception of a few systems which allow to automatically fit simple primitives to measurement data. The need to be able to...

In recent years, the demand for highly detailed building models has clearly risen. Most of the details, which characterize a building, come from its façade. It is obvious that such façade detail is ideally acquired from ground-based sensors. For any street-level data acquisition system, a common problem arises: that of occlusions and hence incomplete data. In the past we have shown how multiima...
