Abstract
This invention relates to a method and system for detecting fire and smoke. The system comprises a processor, a memory and instructions stored on the memory and executable by the processor to: receive a sequence of images from a plurality of cameras; sampling the sequence of images at a certain interval; process each of the sampled images to form a first processed image and a second processed image; extract Binary Large Objects (BLOBs) from first processed image and contours of objects from the second processed image; analyse the BLOB for smoke and the contours of objects for fire; and determine smoke in response to analysing smoke from the BLOBs and fire in response to analysing fire from the contours of objects.
