Embodiment Construction

[0059] The technical scheme of the present invention will be described in further detail below in conjunction with the accompanying drawings and specific examples, so that those skilled in the art can better understand the present invention and implement it, but the examples given are not intended to limit the present invention .

[0060] refer to figure 1 , the video flame detection method that the embodiment of the present invention provides is as follows:

[0061] Step 1, extracting the flame suspicious area in the video image through flame color and brightness and motion foreground, this step includes the following steps again:

[0062] Step 1, convert the video image color space into RGB space, and use the area where the R channel value is greater than the first judgment threshold as the first flame suspicious area;

[0063] Step 2, transforming the color space of the video image into a grayscale image, and using the area whose grayscale value is greater than the second...

Abstract

The invention discloses a video flame detection method, device and system. The method comprises the following steps: extracting a flame suspected area in a video image; carrying out outline extraction processing and image segmentation processing on the flame suspected area to obtain a plurality of flame suspected small rectangular areas; and carrying out flame area extraction on the flame suspected small rectangular areas by the fluctuation characteristics of light stream and flame, and judging whether a video image has flames or not according to an extraction result. The method can obtain the flame suspected area by foreground segmentation and color information, utilizes the light stream to detect the motion characteristics of the flame, judges whether the area has the flame or not through the fluctuation situation of a flame angular point so as to overcome the defects of low video flame detection accuracy, high false alarm rate, high influence degree by noise and the like in the traditional flame detection technology, and solves the problems of poor flame characteristic extraction effect and difficulty in flame positioning in the prior art.

Description

technical field [0001] The invention relates to the technical field of video monitoring, in particular to a video flame detection method, device and system. Background technique [0002] Traditional pyrotechnic detection is mainly for three types of objects: smoke, heat and radiation. Most of them are detected by point sampling sensors for smoke particles, temperature, relative humidity, air transparency, etc. , infrared and other spectrometers for detection. [0003] However, these field-level proximity sensors or professional photoelectric equipment have at least the following limitations: [0004] 1. The use of point sampling sensors for pyrotechnic detection is prone to missing process information, which generally cannot record and contain the spatiotemporal process and state information of flame occurrence and development, which is not conducive to the later playback, analysis and retrieval of events; [0005] 2. The quick response ability is limited. When sampling in...
