Abstract
The disclosure includes imaging systems employing event-based sensors in various applications for analyzing a scene, such as those involved in conveyor systems, mass flow detection systems, portals, machine vision systems, retail settings including checkout stations, and the like. Event-based sensors may be operated in conjunction with frame-based cameras to select frames or subparts of frames or otherwise trigger actions related to the imaging system based on analysis of the events generated by the event-based sensors.
Claims20
An imaging system, comprising:
- a frame-based sensor configured to generate image frames of a scene;
- an event-based sensor configured to generate an event stream;
- and
- a stream processor configured to receive the event stream and analyze the events to determine if a predetermined criteria for the event stream is satisfied, and in response thereto generate a real-time frame trigger to select one or more image frames captured by the image processor for analysis by an image processor.
An imaging system, comprising:
- a plurality of event-based sensors having fields-of-view that at least partially overlap;
- a plurality of laser projectors associated with each of the event-based sensors, and configured to project a complex laser pattern in a corresponding field-of-view of the associated event-based sensor;
- and
- an event stream processor configured to analyze event streams from each of the event-based sensors and to determine at least one characteristic of an object based on the event streams.
