Embodiment Construction

[0064] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in further detail below in conjunction with specific embodiments and with reference to the accompanying drawings.

[0065] Please refer to figure 1 , which is a functional block diagram of a flame judging system according to an embodiment of the present invention. The flame detection system 100 includes an image capture device 102 and a flame detection device 104 , the image capture device 102 is electrically connected to the flame detection device 104 . The image capturing device 102 is, for example, a mobile camera, where the mobile camera is, for example, a camera with omni-directional rotation and zoom (Pan-Tilt-Zoom, PTZ) functions. In other implementations, the image capture device 102 can also be a fixed camera. The image capture device 102 is used for multiple time points T (not shown in figure 1 ) continuously captures a pl...

Abstract

A determining method for fire, a determining system for fire using the same and a determining device for fire using the same are provided. The determining method comprised the following steps. First, a plurality of to-be- analyzed frames is captured in a plurality of time points. Then, whether the to-be- analyzed frames have suspected fire images is determined. Then, a profile size of each suspected fire image is obtained according to an analysis reference point of each suspected fire image. Then, a specific value between the profile sizes of the suspected fire image captured in adjacent two times is calculated. Then, a variation frequency of the specific values is calculated. Then, whether the variation frequency conforms to a fire frequency range is determined. Then, if the variation frequency conforms to the fire frequency range, the suspected fire images are determined to be the image of a real fire.

Description

technical field [0001] The invention relates to a flame judging method, a flame judging system and a flame judging device using the method, in particular to a flame judging method capable of accurately judging flames, a flame judging system and a flame judging device using the method. Background technique [0002] The traditional flame judgment system uses a camera to capture images and judge whether the images have flame images. When the picture has a flame image, the flame judging system further judges whether the flame image is an image of a real flame. [0003] Traditionally, the method of judging the flame is: judging whether the color of the flame image is roughly similar to the color of the real flame, and if so, judging that the flame image is the image of the real flame. However, the traditional way of judging flames is quite inaccurate and often leads to misjudgments. Contents of the invention [0004] (1) Technical problems to be solved [0005] The technical...
