3D imaging with Time-of-Flight (ToF) cameras is a promising recent technique which allows 3D point clouds to be acquired at video frame rates. However, the distance measurements of these devices are often affected by some systematic errors which decrease the quality of the acquired data. In order to evaluate these errors, some experimental tests on a(More)
In recent years, a new generation of active cameras, based on the Time-of-Flight (ToF) principle, has been developed. The main advantages with respect to other 3D measurement techniques are the possibility to acquire data at video frame rates and to obtain 3D point clouds without scanning and from just one point of view. Some experimental tests relative to(More)
Landslide monitoring activities are of paramount importance for landslide hazard and risk assessment. They allow predictions to be made of the phenomenon evolution which can be used to define risk scenarios, especially when urban areas and infrastructures are involved. Over the last decades, spaceborne and, more recently, ground-based interferometric(More)
1. Attributing their origin to specific types of stars, however, often proves difficult. Intermediate-mass stars of 4–8 solar masses are expected to have contributed a large fraction of meteoritic stardust 2,3. Yet, no grains have been found with the characteristic isotopic compositions expected for such stars 4,5. This is a long-standing puzzle, which(More)
In the last few years, several papers dealing with the integration between different surveying techniques (such as photogrammetry, LiDAR, NIR image processing, 2D digital maps, etc.) have been already presented. The main idea of these works is the possibility to overcome the individual weakness of each technique through their combined use, exploiting their(More)
