Automated surveillance systems observe the environment utilizing cameras. The observed
scenario is then analysed using motion detection, crowd behaviour, individual behaviour …

Multi-camera vision systems (MVS) have a larger field of view than a single camera and are
often applied to acquire geometric information of large-scale objects or scenes. Data …

In this article we explain the architecture for the environment and sensors that has been built
for the European project URUS (Ubiquitous Networking Robotics in Urban Sites), a project …

In this paper we approach the problem of in-situ camera calibration using an auxiliary
mobile color-depth camera. The calibration is based on image lines and the Direct Linear …

This paper describes the validation process of a simulation model that have been used to
explore the new possibilities of interaction when humans are guided by teams of robots that …

We present a method to segment dynamic objects from high-resolution low-rate laser scans.
Data points are tagged as static or dynamic based on the classification of pixel data from …

Outdoor camera networks are becoming ubiquitous in critical urban areas of the largest
cities around the world. Although current applications of camera networks are mostly tailored …

This paper presents an efficient graph-based algorithm for the segmentation of planar
regions out of 3D range maps of urban areas. Segmentation of planar surfaces in urban …

This paper proposes a method for calibrating of multi-camera systems where no natural
reference points exist in the surrounding environment. Monitoring the air space at wind …

This paper presents an analysis of uncertainty in the calibration of a network of cameras. A
global 3D scene model, acquired with a LIDAR scanner, allows calibrating cameras with …
