Abstract. Current development of security sensor networks and their processing algorithms use pre-recorded or abstract data streams for testing, often missing important ground truth for validation. This paper proposes a simulation-based test bed, presenting an approach to use commercial off the shelf virtual reality environments to create adaptive simulations of visual and non visual sensors, scenarios and data streams for testing of perceptive algorithms. An example using airborne visual multi object tracking is discussed and validated.

The presented test approach demonstrated the viability of using simulated data for testing and development of perceptive modules (especially visual algorithms), and shows general usability for detection and tracking. The lack of optical and signal errors simplifies processing in synthetic feeds, but these issues will be addressed in future work. The benefits of such an approach are the availability of ground truth data with automatic evaluation, closed loop simulations and prompt repeatability. Also, testing classification and identification methods is of interest, due to the limited variety in terms of textures, and entities.
