Embodiment Construction

[0098] In order to overcome the problems that the current fire detection often has misjudgments that delay the timing of disaster relief or often generate false alarms, this application proposes a novel flame detection method and device. In the flame detection device and method of the present application, The feature comparison device has a database of various features, so that after each feature analysis device completes the analysis, it can be compared with the Gaussian color model in the database, and according to the flickering frequency of the flame, the characteristics of the flame can be further accurately identified to achieve fire detection function. The present invention will be fully understood by the following examples, so that those skilled in the art can complete it, but the implementation of the present invention should not be limited by the following examples.

[0099] see figure 1 , which is a flowchart of an embodiment of the flame detection method of the pr...

Abstract

The invention provides a flame detection method and a detection device which are used for monitoring and identifying whether the flame exists and further improving the flame detection accuracy. The flame detection method and the detection device are used for capturing a plurality of images in a monitoring space, judging whether an image in a dynamic area exists in the images, analyzing a color model and a flicker frequency of the image in the dynamic area, comparing the analyzed result and the characteristics of a reference flame image and coordinating the address change analysis and the area analysis of the image in the dynamic area so as to judge whether the image in the dynamic area is a flame image or not.

Description

technical field [0001] The invention relates to a method and device for detecting flames, in particular to a method and device for detecting flames using image analysis. Background technique [0002] With the increasing scale of offices and factories, and the higher the height of buildings such as department stores, restaurants, gymnasiums, etc., the more special the structure and the more complex the equipment, the general fire safety facilities may not Its validity cannot be guaranteed. If the current traditional monitoring system can be intelligentized, and the captured images can be analyzed by image detection, and calculated by some algorithms to determine whether there is flame in the image, then the added value of the monitoring system can be increased, and it can be effectively Real-time detection and control of disasters. [0003] The so-called image recognition method uses a multi-step algorithm to detect flames. The screen is captured by the monitoring system, ...
