Abstract
The invention relates to methods and systems of detection of smoke or the like in an environment, such as a closed room but not limited thereto, based on video data processing of video data captured in said environment, and wherein the video data processing is for example executed on a computation system.
Claims15
A method for detection of smoke in an environment, comprising the steps of:
- capturing video data, comprising a plurality of image frames;
- computing a value of at least one metric per image frame;
- and determining smoke in said environment by monitoring the change in said value of said metric across said plurality of image frames,
- wherein said metric is representative for contrast at a portion of said image frame.
1 more element
A computer program product, operable on a processing engine, for executing any of the steps of:
- capturing video data, comprising a plurality of image frames;
- computing a value of at least one metric per image frame;
- and
- determining smoke in said environment by monitoring the change in said value of said metric across said plurality of image frames,
- wherein said metric is representative for contrast at a portion of said image frame.

(canceled)
A smoke detection system, comprising:
- a subsystem for video data capturing;
- a computation subsystem, adapted for storage of said video data captured (200) and for executing of any of the steps of:
- capturing video data, comprising a plurality of image frames;
- computing a value of at least one metric per image frame;
- and
- determining smoke in said environment by monitoring the change in said value of said metric across said plurality of image frames,
- wherein said metric is representative for contrast at a portion of said image frame;
- and
- a smoke warning subsystem, being capable of being activated by said computation subsystem.
