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, wherein the imaging system is located at a retail checkout station having the event-based sensor disposed within a housing of a bi-optic barcode reader or external to the housing of the bi-optic barcode reader.
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;
- 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;
- and
- a laser projector configured to project a complex laser pattern in a field-of-view of the event-based sensor for assisting the analysis of the event stream, wherein the analysis of the event stream detects vibrations within the field-of-view of the event-based sensor.
An imaging system, comprising:
- a plurality of event-based sensors having different fields-of-view directed to different conveyor sections of a cross-belt system;
- an event stream processor configured to analyze event streams from each of the event-based sensors and to determine at least one characteristic including at least a position and speed of an object based on the event streams;
- and
- a programmable logic controller configured to synchronize the different conveyor sections responsive to the determined characteristics for merging parcel flow in the cross-belt system.
