This, in turn, often requires the reconstruction of mobility patterns. However, real-time surveillance is often difficult and costly to conduct, especially in criminal scenarios where such process needs to take place clandestinely. In this paper, we consider a vehicular tracking scenario and we propose an offline post hoc vehicular trace reconstruction mechanism that can accurately reconstruct vehicular mobility traces of a target entity by fusing the corresponding available visual and radio-frequency surveillance data. The algorithm provides a probabilistic treatment to the problem of incomplete data by means of Bayesian inference. In particular, we realize that it is very likely that a reconstructed route of a target entity will contain gaps (due to missing trace data), so we try to probabilistically fill these gaps. This allows law enforcement agents to conduct off-line tracking while characterizing the quality of available evidence. %G English %2 https://inria.hal.science/hal-01056371/document %2 https://inria.hal.science/hal-01056371/file/SceneReconstruction.pdf %L hal-01056371 %U https://inria.hal.science/hal-01056371 %~ IFIP-LNCS %~ IFIP %~ IFIP-LNCS-6109 %~ IFIP-TC %~ IFIP-TC11 %~ IFIP-TC6 %~ IFIP-CMS %~ IFIP-2010
