    摘要: A method and system for detecting flames are provided. The flame detection method based on image processing techniques performs the following steps to detecting flames. It first finds one or more bright objects in the images that are captured from videos. A flickering state of a bright object is then determined. To verify the existence of a flame, additionally subsequent images from the instant that a bright object first appears are utilized and the similar steps are applied to them. Finally a flame could be detected if the analyzed results are positive after the aforementioned steps have been performed.

    摘要: A flame detecting method and device are provided to improve the accuracy of flame detection and reduce the possibilities of the false fire alarm. The flame detecting method and device capture a plurality of images of a monitored area; determines whether a moving area image exists in the plurality of images; analyzes at least one of a color model and a flickering frequency of the moving area image to generate a first analyzed result and compares the first analyzed result with a feature of a reference flame image; analyzes at least one of a variation of a location and an area of the moving area image to generate a second analyzed result and compares the second analyzed result with a predetermined threshold; and determines whether the moving area image is a flame image based on results of the comparing steps.
