System And Method For Object And Event Identification Using Multiple Cameras

摘要

A system for identifying objects and events of interest uses one or more cameras with image processing capabilities. The system is includes multiple cameras configured to perform image processing of a scene from multiple angles to extract and transmit meta-data corresponding to objects or people in the scene. The cameras transmit the meta-data to a processing station that is configured to process the stream of data over time to detect objects and events of interest to alert monitoring personnel of objects or events in the scene.

1. A surveillance system comprising:
a plurality of cameras located in a plurality of positions to record a scene, each camera further comprising:
a sensor configured to generate video data of the scene comprising a series of frames;a first network device configured to transmit the video data and feature vectors associated with the video data to a processing station; anda feature extraction processor operatively connected to the sensor and the network device, the feature extraction processor being configured to:
identify a plurality of feature vectors in video data generated by the sensor;transmit only the plurality of feature vectors to the processing station with the first network device in a first operating mode; andtransmit the video data to the processing station with the first network device in a second operating mode only in response to a request for the video data from the processing station; and the processing station further comprising:
a second network device;a video output device; anda processor operatively connected to the second network device and the video output device, the processor being configured to:
receive the plurality of feature vectors generated by each camera in the plurality of cameras with the second network device;identify an object and motion of the object in the scene with reference to the plurality of feature vectors received from at least two of the plurality of cameras;identify an event corresponding to the motion of the object in the scene with reference to a predetermined database of events;generate a request for transmission of the video data from at least one camera in the plurality of cameras; andgenerate a graphical display of the video data from the at least one camera with the video output device to display the object associated with the event.
