Multi-camera system searches images in 3D

16.11.2004


Could boost surveillance in public places



A new three-dimensional multi-camera system that allows viewers to search areas from various vantage points could one day boost surveillance in public places such as airports and train stations, say University of Toronto researchers. The system - based on ideas published in the October proceedings of the 2004 IEEE International Conference on Systems, Man and Cybernetics - allows users to capture images of a scene from multiple angles and automatically sort the images based on their three-dimensional contents. By simply touching an image on a screen, the user can pinpoint a face, suitcase or any point of interest to explore further from different vantage points.

The technology, developed by a team of researchers led by graduate student Sam Mavandadi and Professor Parham Aarabi of U of T’s Edward S. Rogers Sr. Department of Electrical and Computer Engineering, could be used to track objects or individuals in airports, casinos and other large environments. "The system allows an operator to quickly and easily search and explore a large environment observed by numerous cameras," says Mavandadi. "It can also be used in movie and television studios to assist directors in selecting the best vantage point to film."


The system creates a three-dimensional model by assigning relevance values to every point within the user’s selected area of interest. These values are then used to select the most relevant cameras observing an object or individual. While the prototype has been built, the next step is to design the system for commercial use.

Im Focus: Can we see monkeys from space? Emerging technologies to map biodiversity

An international team of scientists has proposed a new multi-disciplinary approach in which an array of new technologies will allow us to map biodiversity and the risks that wildlife is facing at the scale of whole landscapes. The findings are published in Nature Ecology and Evolution. This international research is led by the Kunming Institute of Zoology from China, University of East Anglia, University of Leicester and the Leibniz Institute for Zoo and Wildlife Research.

Using a combination of satellite and ground data, the team proposes that it is now possible to map biodiversity with an accuracy that has not been previously...

Im Focus: Climate satellite: Tracking methane with robust laser technology

Heatwaves in the Arctic, longer periods of vegetation in Europe, severe floods in West Africa – starting in 2021, scientists want to explore the emissions of the greenhouse gas methane with the German-French satellite MERLIN. This is made possible by a new robust laser system of the Fraunhofer Institute for Laser Technology ILT in Aachen, which achieves unprecedented measurement accuracy.

Methane is primarily the result of the decomposition of organic matter. The gas has a 25 times greater warming potential than carbon dioxide, but is not as...

Im Focus: How protons move through a fuel cell

Hydrogen is regarded as the energy source of the future: It is produced with solar power and can be used to generate heat and electricity in fuel cells. Empa researchers have now succeeded in decoding the movement of hydrogen ions in crystals – a key step towards more efficient energy conversion in the hydrogen industry of tomorrow.

As charge carriers, electrons and ions play the leading role in electrochemical energy storage devices and converters such as batteries and fuel cells. Proton...

Im Focus: A unique data centre for cosmological simulations

Scientists from the Excellence Cluster Universe at the Ludwig-Maximilians-Universität Munich have establised "Cosmowebportal", a unique data centre for cosmological simulations located at the Leibniz Supercomputing Centre (LRZ) of the Bavarian Academy of Sciences. The complete results of a series of large hydrodynamical cosmological simulations are available, with data volumes typically exceeding several hundred terabytes. Scientists worldwide can interactively explore these complex simulations via a web interface and directly access the results.

With current telescopes, scientists can observe our Universe’s galaxies and galaxy clusters and their distribution along an invisible cosmic web. From the...
