Embodiment Construction
[0035] The principle of the smoke detection device and method based on video-based multi-feature fusion described in the present invention is that by performing smoke irregularity features, smoke diffusivity features, smoke color features, smoke translucency features, and smoke color features on acquired monitoring images, The detection of saturation characteristics and smoke morphological characteristics is combined with the detection of center motion characteristics, and finally a comprehensive judgment is obtained according to the detection results to achieve the purpose of smoke detection. The implementation method is: mainly obtain the images of the monitoring area through the camera, and then use the data processor (which can be composed of devices with data processing functions such as servers, PCs, or integrated processing centers) to complete the image data processing, and judge whether the monitoring area has smoke production. The present invention is described in de...

The invention discloses a video-based smoke detection device and method according to multi-feature fusion. The method comprises the following steps: a shooting unit and a foreground-extracting unit are used to extract the foreground region of the current image; a foreground central computing unit and a foreground central storing unit of continuous multi-frame are used to obtain the central position information of the foreground region of the continuous multi-frame surveillance area image, then a foreground central motion range calculating unit is used to obtain the external rectangle of the foreground central position; then a foreground central motion range size calculating unit and a central motion characteristic judging unit are used to judge whether the central position has the centralmotion characteristic of smoke; and a noncentral motion characteristic detection unit and a noncentral motion characteristic condition judging unit are used to detect and judge the other characteristics of smoke, and a smoke judging unit is used to perform further judgment according to the obtained result and judge whether smoke exists in the surveillance area. The device and method of the invention are characterized by little computation workload, high accuracy rate, low false alarm rate and missing report rate and the like.
Description
technical field [0001] The invention relates to a video-based multi-feature fusion smoke detection device and method. Background technique [0002] In modern society, more and more electrical appliances are used in various occasions, which increases safety hazards. People's awareness of prevention has gradually increased, and they have begun to pay attention to various security products. At present, there are related monitoring and security products sold in the market, which can be basically divided into two categories in terms of monitoring means: sensor monitoring and video monitoring. Sensor monitoring is to use smoke sensor to detect whether there is smoke and give an alarm. This monitoring method is easily disturbed by external factors (such as: temperature, distance and other external factors), the false alarm rate is high, and the response of the smoke sensor system of the sensor is slow. , requires a certain concentration and temperature, and the loss has been cause...
