Abstract
Embodiments are directed to perceiving scene features using event sensors and image sensors. Enclosures mounted may be on structures arranged to establish a boundary where each enclosure includes an event camera, a beam generator, or a frame camera. The beam generators may be employed to scan paths across objects in a scene that may be outside the boundary. Events may be determined based on detection of beam reflections corresponding to the objects. Trajectories associated with the objects may be determined based on the paths and the events. Objects that may be authorized may be determined based on trajectories associated with authorized objects. Objects in the scene that may be unauthorized may be determined based on trajectories associated with the unauthorized objects. A representation of the unauthorized objects may be determined such that a position and an orientation of the unauthorized objects in the scene may be based on the trajectories.
