Abstract
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.
