Embodiment Construction

[0029] In order to further illustrate the technical means adopted by the present invention and the achieved effects, the technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings and preferred embodiments.

[0030] Such as figure 1 as shown, figure 1 It is a flow chart of the flame detection method of one of the embodiments of the present invention, including the following steps:

[0031] Step S101: Use camera monitoring equipment to capture video stream images of the fire monitoring area, and extract motion history images from each frame of video stream images;

[0032] In practical application, the camera monitoring equipment set in the fire monitoring area, such as a camera, can be used to capture the video stream image of the fire monitoring area, and then extract the motion history image from the video stream image to obtain the motion history image.

[0033] The motion history image (Motion...

Abstract

The present invention relates to a flame detection method and system, wherein the method includes: using camera monitoring equipment to capture video stream images of fire monitoring areas, and extracting motion history images from each frame of video stream images; Carry out class flame color pixel extraction, obtain class flame color image; Carry out logical AND operation to described motion history image and class flame color image, screen out the flame region candidate block; Screen the flame region candidate block of several frame continuous video stream images, And obtain the flame beating times and the edge beating amplitude value of the flame area candidate block of each frame video image; According to the flame beating number of times and the edge beating amplitude value, calculate the probability that each flame area candidate block is a flame area; when the probability If the preset value is exceeded, it is determined that a fire occurs in the fire monitoring area corresponding to the flame area candidate block, which improves the accuracy of fire detection.

Description

technical field [0001] The invention relates to the technical field of fire monitoring, in particular to a flame detection method and system. Background technique [0002] At present, the vast majority of fire monitoring still uses special sensors to detect smoke and fire, such as smoke sensors, temperature sensors, photosensitive sensors or composite sensors composed of these basic sensors. By-products produced during the combustion process, such as optical and optical properties, are used to detect fires. [0003] However, in other cases, these by-products may also be produced, which will lead to a high false alarm rate when using traditional sensor detection equipment to detect fire; in addition, each sensing point of traditional sensor detection equipment can only There are great limitations in monitoring the limited local space around, and it is not suitable for large open outdoor environments. [0004] To sum up, the existing fire detection methods have poor accuracy...
