Video monitoring flame recognition method

The invention discloses a video monitoring flame recognition method. The method includes the following steps that 1, a fundamental analysis image without flames in a monitoring picture is collected; 2, the highlight outline range of the fundamental analysis image is partitioned through edge detection operators; 3, the number of R values and G values on a specific interval within the highlight outline range is counted, and a discrimination feature is obtained accordingly; 4, video monitoring is loaded, the image is intercepted, a highlight area in the image is detected again, and the recognition feature of the image to be recognized is obtained; 5, the discrimination feature is compared with the recognition feature, whether flames happen or not is judged, and the fire behavior level is also judged. By the adoption of the algorithm, the flame recognition efficiency and computational efficiency under a complex environment can be improved.
