Description

(1) Technical field

[0001] The invention relates to an automatic fire extinguishing device based on an omnidirectional visual sensor. (2) Background technology

[0002] The core of automatic fire extinguishing is the early detection of fire and the determination of the flame point. The key technology is to automatically control the nozzle to align with the flame point and spray the fire extinguishing agent near the fire source according to the position of the found flame point, so as to achieve the purpose of automatic fire extinguishing.

[0003] In order to detect and report fires early, and take effective measures in time to control and extinguish fires, an automatic fire-fighting facility installed in buildings or other places is currently one of the indispensable safety technology facilities for modern firefighting. Both at home and abroad attach great importance to automatic fire monitoring. At present, detecting whether a fire has occurred is mainly carried out by co...
