    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.

    摘要: A smoke detecting method is provided. The smoke detecting method includes steps of (a) capturing a video segment for a object and a background; (b) analyzing if an image of the object is moving; (c) analyzing a chrominance variance of the moving object with a corresponding background; (d) analyzing at least one of an edge blur of the image of the background and a flickering frequency of the moving object with its corresponding background; (e) comparing analyzed results obtained from the steps (b)-(d) to a smoke feature; and (f) determining if the moving object is a smoke.
