Smart Spaces and Monitoring Simulation

Abstract

This piece of work is framed in our group research and is about behaviors identification of the smart spaces monitoring. Particularly, if this monitoring uses cameras, some habitual problems related to lights and shadows in the scene because they make the task of recognition difficult, the identification of objects and even the images captured to analyze the correct functioning of these systems appear. However, the experimentation is difficult in any case because the installation of cameras and other sensors are laborious and it can entail a high cost. Thus, to solve these problems we are developing a simulator in order to create a scene with actors, objects and sensors, which the user requires and can reproduce a defined plot. Thereby we can get two objectives: a) Check the correct location and appropriate characteristics of the equipment installed, virtually, and b) The system can emulate the event generations of the real system and with this it can confirm the utility of the installation. In the global frame of our research, besides, it allows to unhook of the physical level and focus on the behavior interpretation from that virtual smart space. Thus, the problems of generating images and events, which probe the correct functioning of the systems and other possible failures derived directly from the images captured by the devices, are solved.

The proposal is showed in this article and is also exemplified with a possible real scene, developed indoors. The objective consists of elaborating a preventive diagnosis about the activity monitorized and detecting what is happening in a particularly moment. In all, it simulates smart spaces and monitoring behaviors. This piece of work emphasizes: (1) The capacity of generating a lot of scenarios with innumerable characteristics, reproducing scenes which exist in real life, which implies that simulated sensors generate the correct events, events obtained from the simulated scene observe. (2) From the simulated events or from the virtual images directly, the interpretation of the actions performed by the actors in the plot and the interaction with objects placed on stage, getting all these events associated to the activities observed.
