Flame position identification method applied to flame cutting

The invention relates to the technical field of flame cutting visual tracking, in particular to a flame position recognition method applied to flame cutting, which comprises the following steps: acquiring a flame cutting video through a camera arranged beside a flame cutting machine, and transmitting the acquired flame cutting video to a processor; and the processor receives the collected flame cutting video stream and processes the flame cutting video stream so as to identify the current position of the flame during flame cutting operation. Wherein the second step specifically comprises the step of establishing a color model of flames in flame cutting operation; segmenting the image of the flame cutting video based on a color model to obtain a flame region; a profile curve position of the CV model is determined based on the flame region, thereby identifying a flame position. The flame position in the flame cutting process is automatically recognized through vision, and therefore the flame cutting condition c
