The invention relates to the fire smoke identification system technology field and especially relates to a fire smoke identification system based on an optical flow method. The system comprises a firesmoke image acquisition unit, a fire smoke image identification unit, a signal output unit and an alarm unit. The fire smoke image acquisition unit is electrically connected to the fire smoke image identification unit. The fire smoke image acquisition unit is electrically connected to a signal output unit. The signal output unit receives a comparison result transmitted by an image comparison module in the fire smoke image identification unit. The signal output unit determines the comparison result transmitted by the image comparison module. The signal output unit is electrically connected tothe alarm unit. The alarm unit can carry out simultaneous sound and light alarm, and can also realize remote alarm. In the identification of fire smoke, the smoke itself is compared and identified based on the optical flow method. The system has a high identification ability and can be applied to fire prevention in various fields.
Description
technical field [0001] The invention relates to the technical field of fire smoke recognition systems, in particular to a fire smoke recognition system based on an optical flow method. Background technique [0002] Optical flow is a concept related to object motion detection in the field of view, which is used to describe the motion of the observed object, surface or edge caused by the motion of the observer. Optical flow is very useful in pattern recognition, computer vision, and other image processing fields. It can be used for motion detection, object cutting, calculation of collision time and object expansion, motion compensation coding, or three-dimensional measurement through object surfaces and edges, etc. etc. The advantage of the optical flow method is that the optical flow not only carries the motion information of the moving object, but also carries rich information about the three-dimensional structure of the scene. It can detect the moving object without knowing...
