"An interesting addition to the current state of the art would be the extension of an ontology with modeling the precise fields of views of all cameras to allow a detailed calculations of camera coverage through e.g. overlapping FOV volumes. This would require the development of a spatial calculus that could be represented in the ontology in either static (immovable cameras) or dynamic spatio-temporal configurations (when is a feature detected in e.g. rotating cameras). For this, the notion of 'space' must be extended beyond the mere physical spaces from a static building models." . "2"^^ . . . . "2019-11-26T09:05:11+01:00"^^ . .
