Abstract
We consider the problem of controlling mobile sensing systems in order to improve the accuracy and efficiency of information acquisition in scenarios such as environmental monitoring, search and rescue, surveillance and reconnaissance, and simultaneous localization and mapping (SLAM). A multi-sensor active information acquisition problem capturing the common characteristics of these scenarios is formulated. The goal is to design control policies for the sensors, which minimize the entropy of the estimation task conditioned on the future measurements. First, we provide a non-greedy centralized solution, which is computationally fast, since it exploits linearized sensing models, and memory efficient, since it exploits sparsity in the environment model. Next, we decentralize the control to achieve linear complexity in the number of sensors and provide suboptimality guarantees. The combination of these techniques is an effective and scalable approach for controlled information acquisition with multiple sensors. For example, when applied to the multi-robot active SLAM problem, our results enable a decentralized nonmyopic solution that exploits sparsity in the planning process. Future work will focus on an experimental validation of our algorithms in the Smart City test beds and on a formulation of the active information acquisition problem, which can handle discrete-state sensor and target models. The latter is particularly useful for hypothesis testing and object recognition scenarios.
