A method is generally provided for adjusting a pattern projection rate in an active perception system, comprising the steps of observing a scene with an event-based sensor array; projecting a current light pattern of a sequence of light patterns on the scene for a given interval of time; retrieving events generated by the event-based sensor array in response to the projection of the current light pattern; monitoring a property of the event retrieval progress; and dynamically controlling the projection of the light pattern based on the property.

Method for automatically adapting a pattern projection rate in an active perception system

A system () for detecting dynamic secondary objects () that have a potential to intersect the trajectory () of a moving primary object (), comprising a vision sensor () with a light-sensitive area () that comprises event-based pixels (), so that a relative change in the light intensity impinging onto an event-based pixel () of the vision sensor () by at least a predetermined percentage causes the vision sensor () to emit an event () associated with this event-based pixel (), wherein the system () further comprises a discriminator module () that gets both the stream of events () from the vision sensor () and information () about the heading and/or speed of the motion of the primary object () as inputs, and is configured to identify, from said stream of events (), based at least in part on said information (), events () that are likely to be caused by the motion of a secondary object (), rather than by the motion of the primary object (). Vision sensors () for use in the system (). A corresponding computer program.
