Abstract
An intelligent video analysis method and system logically selects only surveillance cameras associated with an event and assigns different ranks to the selected surveillance cameras according to the importance thereof. Thereafter, more video analysis resources are assigned to a surveillance camera of high importance, thereby rapidly and efficiently performing video analysis.
Claims16
A video surveillance method comprising:
- receiving information including event metadata about an event of an object that is detected by at least one camera among a plurality of cameras, the event metadata indicating event type, event time, event location, and a direction and speed of the object;
- selecting at least one logical camera group from the plurality of cameras;
- dynamically allocating resources to the cameras of the at least one logical camera group to achieve network load balancing by changing a number of video slots to be assigned to the plurality of cameras based on the event metadata;
- wherein the selecting of the at least one logical camera group further comprises:
- grouping cameras that are physically connected to a camera that detected the event as a physically connected camera group;
- and
- logically selecting cameras, which are related to the event, from among the physically connected camera group, based on the event metadata.

A video surveillance method comprising:
- detecting an event of an object by at least one camera among a plurality of cameras;
- sending information including event metadata about the event, the event metadata indicating event type, event time, event location, and a direction and speed of the object;
- and
- receiving a resource allocation,
- wherein the allocation is performed by dynamically allocating resources based on respective priority values of the cameras of the at least one logical camera group with respect to a relevance to the event;
- wherein the at least one logical camera group is selected from the plurality of cameras by selecting cameras having a physical network connection with at least one camera, cameras being within a certain radius from the at least one camera, or cameras being within a same surveillance zone as the at least one camera.
3 more elements
A video analysis system for analyzing a video, the video analysis system comprising:
- a logical camera group generator configured to generate at least one logical camera group related to a camera detecting an event;
- a load balancing processor configured to perform load balancing with respect to data transmitted from a plurality of cameras based on a relevance to the event
- a video analysis server performing further analysis based on event metadata about the event detected by a camera among the plurality of cameras;
- and
- wherein the logical camera group generator is further configured to group cameras that are physically connected to the camera that detected the event as a physically connected camera group;
- and logically select cameras, which are related to the event, from among the physically connected camera group, based on the event metadata.
