Problems solved by technology
However, in these methods, some algorithms use traditional color spaces such as RGB and YUV for flame color feature recognition, and the misjudgment rate is high; some algorithms first perform flame feature analysis, and then perform moving target recognition, resulting in slow calculation speed. higher operating costs
Other algorithms analyze and detect dynamic features such as flame shape, and the algorithm structure is complex and the false positive rate is high.

Description
Technical field [0001] The invention relates to a video analysis system based on a video image analysis flame detection device, in particular to perform flame detection and warning by analyzing the pixel color characteristics in a video image collected in real time, and belongs to the technical field of intelligent fire monitoring. Background technique [0002] Fire monitoring and early warning systems play a very important role in many fields, including large-scale building fire protection, forest fire protection, and natural environment monitoring. Traditional fire monitoring technologies and devices include particle type smoke sensors, infrared and laser technologies. The particle type smoke sensor requires smoke particles to enter the sensor to cause an alarm. Infrared and laser technology also requires smoke shielding to trigger an alarm. In addition, for large-space buildings and outdoor environments, a large number of sensor devices are required to achieve higher monitorin...
