A Survey of Rigid 3D Pointcloud Registration Algorithms
The main contribution of this paper consists of an overview of registration algorithms that are of interest in the field of computer vision and robotics, for example Simultaneous Localization and Mapping.
A Benchmark Survey of Rigid 3D Point Cloud Registration Algorithms
This survey studies different stateof-the-art registration algorithms, which are able to determine the motion between two corresponding 3D point clouds, and concludes that the ICP point-to-surface method is the most precise algorithm.

A comparison of three proximity methods, one fingerprinting method and three ranging methods using Sigfox communication messages achieves the best result compared to other signal strength localization methods.
MapFuse: Complete and Realistic 3D Modelling
A novel method to simulate a complete indoor environment that can be used for evaluating a radio propagation model efficiently is presented and a complete volumetric model is created by merging an initial model of the environment with the result of RGB-D SLAM based on real sensor measurements.
3DVFH+: Real-Time Three-Dimensional Obstacle Avoidance Using an Octomap
This algorithm is based on the 2D VFH+ obstacle avoidance algorithm and uses the octomap framework to represent the three-dimensional environment and is able to calculate a new robot motion with an average time of 300 μs.

This paper presents a method to localize a DASH7 mobile node based on a single message and a deterministic propagation model so that single measurement localization approach is possible without maintaining a fingerprint database.
Large-Scale Crowd Analysis through the Use of Passive Radio Sensing Networks
A set of experiments in which a passive Radio Frequency sensor network is installed in different environments containing thousands of human individuals and the accuracy with which the resulting measurements can be used to estimate the sizes of these crowds is described.
