Résumé / Abstract
To improve safety and efficiency, camera networks in public transport get bigger and bigger. However, operators can only monitor a few cameras at a time, hence the need to automate the monitoring tasks through computer vision. We describe an approach consisting of small, localized computers each dedicated to the local image processing of only one or two cameras, interconnected through a standard computer network carrying only the small amount of useful data extracted from the image processing. This short paper describes the implementation of this system, as well as the four tasks that have been implemented on it. These examples belong to both incident detection and traffic measurement tasks, and are better implemented in the decentralized architecture we propose. These processes have all been intensively tested in real life conditions within several types of transport network, such as an airport and underground railways. Trials show the efficiency of the tested solutions.
