Abstract: In one implementation, a three-dimensional image sensing system is provided that includes at least one processor that detects, from an image sensor, one or more first events based on reflections caused by electromagnetic pulses associated with a plurality of projected line patterns and corresponding to one or more first pixels of the image sensor. The at least one processor also detects, from the image sensor, one or more second events based on the reflections and corresponding to one or more second pixels of the image sensor, identifies a line corresponding to the one or more second events and the one or more first events, calculates three-dimensional rays for the one or more first pixels and the one or more second pixels based on the identified line, and calculates three-dimensional image points for the one or more first pixels and the one or more second pixels based on the three-dimensional rays and a plane equation.

Abstract: The present disclosure generally relates to systems and methods for three- dimensional image sensing. More specifically, and without limitation, this disclosure relates to systems and methods for detecting three-dimensional images, and using asynchronous image sensors for detecting the same. In one implementation, at least one processor determines a plurality of patterns associated with a plurality of electromagnetic pulses emitted by a projector onto a scene; receives, from an image sensor, one or more first signals based on reflections caused by the plurality of electromagnetic pulses; detects one or more first events corresponding to one or more first pixels of the image sensor based on the received signals; based on the one or more first events, initializes one or more state machines; receives, from the image sensor, one or more second signals corresponding to the reflections; detects one or more second events corresponding to one or more second pixels of the image sensor based on the received signals; determines candidates for connecting the one or more second events to the one or more first events; and determines three-dimensional points for the one or more first pixels and the one or more second pixels based on the candidates and the one or more state machines.
