The system scans and locates the suspected fire point through the combined visual processing of monocular camera, binocular camera and infrared camera with high positioning accuracy. Further fire point determination is carried out through a series of characteristics such as heat analysis, color distribution characteristics of the flame, flame change characteristics, flame area spread growth characteristics, shape change characteristics of the flame, and flame edge change; locating the fire point spatial coordinates through RTK positioning and binocular parallax calculations; algorithmic modeling of water column trajectory and waterway trajectory ejected from the fire cannons and the influence of environmental factors in the outdoor scene. The model integrates the correction of environmental parameters such as wind direction, wind speed, air pressure, etc., and ultimately the position of the water point is precisely controlled by controlling the angle of water discharge from the fire cannon, the outlet pressure and flow rate, so as to realize the automatic fire point tracking and fire extinguishing control.
